What is Green Manufacturing?

Green manufacturing refers to the responsible production of goods through processes designed to minimize a manufacturer’s environmental impact. Key focuses of green manufacturing include:

●      Conserving natural resources. Processes powered by fossil or nuclear fuels deplete the supply of non-renewable resources while releasing greenhouse gases and other pollutants into the air. Replacing these energy sources with renewable alternatives like solar, wind, or hydropower reduces the strain on the environment.

●      Improving energy efficiency. Energy efficiency can be improved in several ways, such as installing CFL or LED lights, utilizing fans or natural airflow to supplement HVAC operations, turning off machinery when not in use, etc. Regardless of the approach, improved energy efficiency decreases the demands that businesses place on the environment.

●      Reducing pollution and waste. Transitioning to renewable resources for energy-heavy processes significantly reduces the volume of pollutants generated by businesses. Reusing, selling, recycling, or composting excess raw materials minimizes waste production and output.

Businesses interested in adopting green manufacturing practices should assess their current environmental impact to gauge options and next steps.

Benefits of Green Manufacturing

While the environment stands to gain a great deal from companies converting to green manufacturing, the businesses on the frontline benefit as well through things like:

  • Improved bottom line from decreased material costs, overhead expenses, and downtime
  • Increased employee morale and motivation related to higher earning potential from a more specialized skills base
  • Enhanced public relations due to additional job creation and a demonstrated community focus

What Is a Centrifugal Pump?

A centrifugal pump is a machine that uses rotation to impart velocity to a liquid, resulting in fluid flow, by converting rotational kinetic energy into hydrodynamic flow energy. It is the most common type of pump used in industrial processes and household purposes. Centrifugal pumps are made up of multiple components that work together, creating a device that is used in a variety of applications.

What Components Make Up a Centrifugal Pump?

There are several components that make up a centrifugal pump, including:

  • Impeller. The impeller rotates at high speeds to impart velocity to a liquid.
  • Casing. The casing serves as a pressure containment vessel and directs the flow of liquid in and out of the centrifugal pump.
  • Pump Shaft and Shaft Sleeves. The impeller is mounted on a pump shaft, usually made of steel or stainless steel, which transmits torque from the motor to the impeller. A protective metal shaft sleeve is threaded or slid onto the portion of the shaft inside the sealing arrangement to hold the impeller in place.
  • Bearing. Bearings are designed to constrain motion and reduce friction between the shaft and the stator.
  • Rotational Mechanics (Pumping Unit). The pumping unit is crucial to the functionality of a centrifugal pump and typically contains two parts: a pump and a driver. The driver, which is usually an electric motor, imparts rotational power to the pump.

Common Applications of Centrifugal Pumps

Centrifugal pumps are used in a variety of industries, including agriculture, dairy, food-processing, mining, chemical plants, pharmaceutical, municipal water plants, oil refineries, and more.

These industries use centrifugal pumps for the following applications:

  • To supply water for daily use

Everything You Need to Know About Positive Displacement Pumps

Positive displacement pumps play a critical role in fluid handling and processing applications across a wide range of industries. While centrifugal pumps have replaced them as the standard for low-pressure, high-volume pumping operations, they remain necessary for highly specialized pumping applications. The following article provides an overview of positive displacement pumps, outlining what they are, how they work, and the types available in the market.

What Is a Positive Displacement Pump?

Positive displacement pumps rely on a variety of rotating or reciprocating components—e.g., diaphragms, gears, pistons, rollers, or screws—to draw in fluid into the pump chamber on the suction side and push fluid out of the pump chamber on the discharge side. The suction side has an expanding cavity while the discharge side has a decreasing cavity. This design allows the pump to generate the high pressures needed to move materials with high-viscosities and/or in precise volumes.

How Does a Positive Displacement Pump Work?

Positive displacement pumps rely on the principle of fluid displacement to move fluid from the inlet to the outlet. During each cycle of operation, the rotating or reciprocating component forces a fixed amount of fluid into the expanding cavity and out of the decreasing cavity. The amount of fluid displaced depends on the displacement mechanism employed. The rate of flow will remain constant, regardless of the discharge pressure.

Unlike centrifugal pumps, positive displacement pumps do not have shut-off heads. As a result, they cannot be operated against closed valves on the discharge side. Otherwise, the pump will continue to discharge fluid until the pressure in the discharge line is sufficient enough to damage the line and/or the pump. For this reason, industry professionals often add an internal or external safety or relief valve to the discharge side of positive displacement pumps as a preventative measure.

Types of Positive Displacement Pumps

There are two main classifications of positive displacement pumps: reciprocating pumps and rotary pumps.

Reciprocating Positive Displacement Pumps

Reciprocating pumps rely on components that perform a repetitive linear motion—i.e., up-and-down or back-and-forth—to create the pressure that draws fluid into and pushes fluid out of the pump chamber. Examples of reciprocating pump components include plungers, pistons, and diaphragms. For pumps with pistons or plungers, the suction stroke of the component opens the inlet valve and closes the outlet valve, allowing fluid to enter the pump chamber. The forward stroke of the component closes the inlet valve and opens the outlet valve, allowing fluid to exit the pump chamber. For pumps with diaphragms, the flexible membrane expands and compresses to draw the liquid in and discharge it.

Rotary Positive Displacement Pumps

Rotary pumps utilize components that perform a rotating motion to draw in and push out fluid. Examples of rotary components include gear and screws. The element develops a liquid seal with the pump casing. As a result, it creates suction as it rotates, which pulls fluid into the pump chamber at the suction point and pushes fluid out of the pump chamber at the discharge point.

Four Types of Positive Displacement Pumps

There are numerous types of positive displacement pumps and understanding how they work is crucial to success. Below, Glauber Equipment provides information on common types of pumps to help readers understand the differences and choose the best type for their intended application.

Diaphragm Pumps

Diaphragm pumps, also known as membrane or air operated diaphragm pumps, are positive displacement pumps that use the combination of a thermoplastic, rubber, or PTFE diaphragm and suitable valves to pump a fluid. When operated at a given speed, their rate of flow does not vary significantly with discharge or pressure.

Diaphragm pumps can transfer a wide variety of liquids, including chemicals, with various viscosities and high solid contents. Their design allows them to be constructed with numerous body materials and diaphragms, enabling them to handle aggressive chemicals such as acids. Diaphragm pumps are used primarily in continuous applications such as general plants, industrial, and mining applications.

Gear Pumps

Gear pumps are a type of positive displacement pump that uses two or more gears to create a vacuum that drives the liquid through the pump, forcing a constant amount of fluid with each revolution. Gear pumps don’t contain any valves and are capable of operating under high forces, making them most suitable for efficiently pumping thick liquids such as oils, paints, and solvents.

Lobe Pumps

Similar to gear pumps, lobe pumps operate with the counter-rotation of two lobes moving fluid through the interior of a chamber. The shaft-mounted lobes are turned with an external gearbox used to transfer energy.

The gearbox has timing gears which enable synchronized rotation to keep the lobes from contacting and create the pressure change required to induce fluid movement. As the energy from the drive shaft is transferred to the lobes, the pressure inside the chamber decreases, causing the fluid to flow.

Lobe pumps are highly efficient, reliable, rust-resistant, and hygienic, making them suitable for various applications, including chemical, pulp and paper, food, beverage, biotechnology, and pharmaceutical.

Piston Pumps

Piston pumps are positive displacement pumps that use a piston, diaphragm, or plunger to move fluids by creating a high force seal. The piston is typically attached to a shaft that is connected to a rotary component. As the rotary component turns, it transfers energy to the shaft, which operates the piston and displaces the fluid.

There are many types of piston pumps, all featuring at least one piston or plunger used to displace fluid. Piston pumps are used as hydraulic pumps for powering heavy equipment and are also used in many smaller machines, such as paint sprayers. They are capable of operating under a wide range of pressures and are good with thick liquids, slurries, and abrasives, making them suitable for various industrial applications such as water irrigation, housing, commercial buildings, fire pumps, sprinkler systems, and more.

Differences Between Centrifugal and Positive Displacement Pumps

Pumps are mechanical devices vital to facilitating the movement of fluid. Variances in performance, ability to manage fluid viscosity, efficiency, and more mean there is no one-size-fits-all pump for every application. There are two main classes of pumps—centrifugal and positive displacement—and having a clear understanding of the differences between them is crucial when selecting the appropriate pump for the job at hand.

What Is a Centrifugal Pump?

centrifugal pump is a mechanical device responsible for moving fluid by the use of centrifugal force. They contain three primary components:

  • Impeller:Hydraulic rotor containing a series of curved vanes whose motion accelerates fluid.
  • Casing:Mechanical component surrounding the impeller that collects fluid and controls discharge pressure.
  • Rotational mechanics:Elements (like the shaft and motor) that rotate the impeller in its casing.

Centrifugal pumps work as mechanical energy applied to the impeller imparts a centrifugal force on the surrounding water, pushing it outward radially. These high-velocity particles are captured in the casing and converted into a controlled and stable flow before being directed toward the discharge point. As the velocity of the liquid decreases inside the casing, kinetic energy is converted into pressure, helping to overcome the resistance of the pumping system.

What Is a Positive Displacement Pump?

Positive displacement pumps move fluid by trapping fixed volumes and displacing them mechanically. There are two main categories of positive displacement pumps:

  • Reciprocating:Repetitive strokes of pistons, plungers, or diaphragms create discharge pulses in measured amounts.
  • Rotary:Rotating cogs or gears create a seal that allows liquid to be carried from inlet to discharge.

Both types work using variable-volume cavities to apply suction and compression to control fluid pressure as it moves through the system.

Difference Between Centrifugal Pumps and Positive Displacement Pumps

Both styles of pumps move fluid, yet they operate in distinct ways.  Below are some key differences between these pumps.

Performance (Flow)

The flow rate of a fluid is its volume passing through a given area in a unit of time. Both pumps can regulate flow by changing the speed of moving water, though they do so utilizing different mechanisms. The flow rate in a centrifugal pump is highly susceptible to the impacts of pressure. One of the main benefits of using a positive displacement pump is its ability to produce a consistent flow rate due to its fixed volume displacement.


Viscosity refers to the friction between the molecules in a fluid and is responsible for determining the energy that will be required to make the fluid flow. Centrifugal pumps transfer fluids with relatively low viscosity, like water or thin oils. Because these pumps have variable flow rates, increased viscosity of the fluid will cause a radical decrease in the efficiency of the pump. Although flow rates remain more consistent in positive displacement pumps, viscous fluids fill chambers more quickly to improve volumetric efficiency.


Centrifugal pumps are most effective within 80-110% of their best efficiency point (BEP) or the flow at which the pump performs most optimally based on its intended application. In contrast, the efficiency of positive displacement pumps improves as pressure increases.

Common Applications

Centrifugal pumps can handle large volumes of fluid, produce higher flow rates, and throttle those rates over a broader range. These characteristics position them as the ideal option for applications including:

  • Agriculture
  • Industrial production
  • Municipal power generation
  • Petroleum

Positive displacement pumps excel in applications dealing with high pressure and high viscosity and requiring consistent performance. They are often used for:

  • Chemical injection
  • Oil production
  • Paint spraying
  • High force washing

Power-Saving Solutions for Low Gas Flow Situations

In landfills, biodegradable waste generates variable levels of landfill gas throughout its decomposition process. The usable landfill gas—i.e., the one suitable for powering combustion operations—generally ranges around 50% methane by volume. As such, landfills that produce low calorific volume (low-CV) gas—i.e., gas with less than 50% (typically 30% or lower) methane by volume—are less likely to run effectively and efficiently. Two of the factors that affect whether a landfill produces low-CV gas are the quality (i.e., the methane content) and the quantity (the flow/volume collected) of the extracted gas. 

The following article addresses the latter point—i.e., landfills with low flow/volume landfill gas collection rates. While this condition significantly reduces the energy efficiency of the landfill, the proper landfill gas management plan can minimize the severity of the effect.

The Importance of Conserving Power When Gas Flow Is Low

As indicated above, low gas flow significantly affects a landfill’s overall efficiency and effectiveness. As such, handling the issue properly if and when it occurs is critical. In addition to identifying and resolving the cause of low flow (e.g., inadequate levels of overall waste or biodegradable compounds), it is important to conserve power until an appropriate solution is implemented. 

One potential solution for conserving power in low gas flow situations is integrating variable frequency drives (VFDs) in the landfill’s motorized systems. These devices allow the systems to change speeds to accommodate more efficient and effective power consumption requirements. However, they are expensive, especially when used in medium-voltage and high-horsepower systems. 

Power-Saving Solutions for Low Gas Flow Situations at GEC

At Glauber Equipment Corporation (GEC), we specialize in fluid and air flow equipment and systems. For the biogas and landfill markets, we provide gas separation and compression solutions, including blowers, compressors, and dehydration units, all of which serve a critical role in the waste decomposition and gas production processes. 

The compression stages of the processes rely on compressors. For these operations, we supply between two to four units, all of which are engineered to shut off in low flow conditions to conserve energy. For example, if the flow drops to 75% the normal operating conditions, one of four compressors may shut off to balance flow output with power input. Another advantage of this design is that repair and maintenance can be performed without halting production completely.

How to Choose Pumps for Your Food & Beverage Processing

During food and beverage processing operations, maintaining hygienic processing conditions and preventing contamination of the products are top priorities. To accomplish these goals, facilities employ equipment, such as pumps, to achieve and maintain hygienic conditions during food and beverage processing operations.

Selecting the Proper Pump

The food and beverage processing industry employs a variety of pump types for various processing applications. Some of the pump types most often used in the industry include:

  • Air-operated double diaphragm
  • Centrifugal
  • Peristaltic hose
  • Progressing cavity
  • Reciprocating positive displacement
  • Rotary lobe
  • Rotary piston


glauber-pump-food-beverageIn light of the wide selection of pumps available, choosing the right one for a food and beverage processing application is critical and requires careful consideration of the different pump types and their properties. Among these considerations are the specific processing challenges related to the handling of each food or beverage type.

Pumps used in the food and beverage industry must provide solutions to the two main processing challenges: i) separating mechanical elements driving pump compression from the processed product and ii) maintaining the integrity of the processed product. Each pump type accommodates these challenges in different ways, leading to individual sectors preferring a specific type and design depending on the requirements of their processing operations. For example:

  • Lobular pumps produce a lower flow rate and tend to require a larger initial investment.
  • Progressing cavity pumps apply lower levels of shearing to the production medium, making it the better option for processing fragile or viscous fluids.
  • Double diaphragm pumps also provide lower levels of fluid shearing but with greater clearance allowances.
  • Centrifugal Pumps are suitable for most beverage, oil, and batter processing operations.
  • Positive Displacement Pumps are the most versatile. They find application in a wide range of processing operations, including wine production and the processing of thicker products and slurries, such as pie fillings, baby food, cheese, cream, icing, dressings, meat emulsions, mayonnaise, tomato sauces and pastes, and similar substance types.

In addition to maintaining the integrity of the food product throughout processing, pumps must also comply with strict regulatory standards, including:

  • FDA CFR 21.177 (safe elastomeric material use in pump construction)
  • 3A (material use combined with smart design with CIP and COP, minimizing contamination)
  • EHEDG (adds additional performance standards and CIP testing to 3A)

These standards are in place to help eliminate contamination throughout food and beverage processing, and compliance with them is an essential element in the design of the pumps used by the industry.
