Types of Chemical Pumps

Centrifugal Pumps
Centrifugal pumps are the most common type of chemical pumps used in various industries. They work by converting rotational energy from an impeller into kinetic energy, which in turn transfers fluid to the discharge outlet. Centrifugal pumps are reliable, efficient, and cost-effective, making them suitable for low-to-medium viscosity fluids with low solid content.

Diaphragm Pumps
Diaphragm pumps are positive displacement pumps that use a flexible diaphragm to transfer fluids. They work by moving the diaphragm back and forth, creating a vacuum that draws fluid into the pump chamber and then pushes it out. Diaphragm pumps are ideal for transferring fluids with high solids content or for applications that require gentle pumping action.

Peristaltic Pumps
Peristaltic pumps are positive displacement pumps that use a flexible tube and rollers to transfer fluids. They work by squeezing the tube, which creates a vacuum that draws fluid into the pump and then pushes it out. Peristaltic pumps are suitable for transferring viscous and abrasive fluids or for applications that require accurate dosing.

Piston Pumps
Piston pumps are positive displacement pumps that use a reciprocating piston to transfer fluids. They work by pulling fluid into the pump chamber and then pushing it out through a discharge valve. Piston pumps are suitable for high-pressure applications or for transferring fluids with high viscosity and solids content.

Magnetic Drive Pumps
Magnetic drive pumps, also known as mag-drive pumps, use a magnetic coupling to transfer fluids without any physical contact between the motor and the pump. They work by creating a magnetic field that drives the impeller, which in turn transfers fluid. Magnetic drive pumps are ideal for transferring hazardous and corrosive fluids or for applications that require zero leakage.

Gear Pumps
Gear pumps are positive displacement pumps that use two meshed gears to transfer fluids. They work by trapping fluid between the gear teeth and the pump casing, which then transfers it to the discharge outlet. Gear pumps are ideal for transferring low-to-medium viscosity fluids and for applications that require high flow rates.

Progressive Cavity Pumps
Progressive cavity pumps, also known as helical rotor pumps or eccentric screw pumps, use a helical rotor and a stator to transfer fluids. They work by trapping fluid between the rotor and the stator, which then transfers it to the discharge outlet. Progressive cavity pumps are ideal for transferring highly viscous and abrasive fluids or for applications that require gentle pumping action.

Air-Operated Double Diaphragm Pumps
Air-operated double diaphragm pumps, also known as AODD pumps, use compressed air to transfer fluids. They work by using two diaphragms to pump fluid in and out of the pump chamber. AODD pumps are ideal for transferring fluids with high solids content or for applications that require portable pumping solutions.

Rotary Lobe Pumps
Rotary lobe pumps use two rotating lobes to transfer fluids. They work by trapping fluid between the lobes and the pump casing, which then transfers it to the discharge outlet. Rotary lobe pumps are ideal for transferring low-to-high viscosity fluids and for applications that require low shear pumping action.

Vane Pumps
Vane pumps are positive displacement pumps that use vanes to transfer fluids. They work by trapping fluid between the vanes and the pump casing, which then transfers it to the discharge outlet. Vane pumps are ideal for transferring low-to-medium viscosity fluids and for applications that require high flow rates.

Chemicals Pump Benefits

Corrosion resistance
First, the pumps allow manufacturers and processors to transfer a wide variety of fluids, even those that would quickly cause corrosion in other pumps.
Second, the pumps offer long service life. Even when used for extremely
Corrosive chemicals, the pumps are able to withstand these conditions and deliver enhanced return on investment.

Energy efficiency
Chemicals pumps rank high in energy efficiency compared to other pumping technologies. Their efficiency reduces costs both in the short term and over the life span of each unit.

Smooth flow
Some pumps produce pulsing flow. Chemicals pumps avoid pulsing.

Proven reliability
Chemicals pumps are a solid choice when reliability is critical. Evaluate design and construction features to ensure the specified pump will be durable enough to operate under the most extreme conditions in the planned application.

Low maintenance
Despite long life spans, some pumps may require frequent routine maintenance that can make them costly to operate. Fortunately, chemicals pumps have low routine maintenance requirements.

Size versatility
Chemicals pumps are available in a wide range of sizes. The various models can accommodate flow rates ranging from less than 1 gallon per minute (gpm) (1 liter per minute [lpm]) to greater than 1,400 gpm (318 cubic meters per hour [m3/hr]).

Application versatility
The same pump configuration is not suitable for every application. With chemicals pumps, various configurations are available to provide solutions for multiple applications. These versatile pumps are available in three configurations:
● Flooded suction: These can be used when the liquid supply level is above the pump's centerline or impeller eye.
● Self-priming: These can be used when the liquid supply level is below the pump's centerline or impeller eye.
● Vertical: These pumps are typically submerged in the fluid, making them suitable for applications where space is limited.
The option of mechanical seal or magnetic drive sealless designs adds to the versatility of these pumps.

How Chemical Pumps Work

A chemical pump is a specialized device used primarily in industries where the handling of corrosive, abrasive, or hazardous fluids is necessary. These pumps are designed with materials and construction that ensure compatibility with the types of chemicals being transferred.

Materials such as stainless steel, alloys, and fluoropolymers are commonly used due to their resistance to chemical corrosion and reactive properties. This ensures that the pump components remain intact and reliable over time, even when exposed to aggressive substances.

The working principles of chemical pumps revolve around maintaining the integrity of the fluids being transferred while ensuring operational safety. One crucial aspect is the sealing mechanism employed in these pumps. Given the potential hazards associated with chemical leaks, chemical pumps are equipped with advanced sealing technologies.

These may include mechanical seals that prevent fluid leakage by creating a barrier between moving parts, or magnetic couplings that use magnets to transmit torque through a hermetically sealed barrier, eliminating the need for conventional seals altogether.

Chemical pumps operate using various types of pump mechanisms depending on the specific requirements of the application.

How to Choose the Right Chemical Pump

Choosing the right chemical pump is necessary to operate your industrial workflows efficiently. There are several key factors you can consider while choosing a chemical pump.
Here's a guide to choosing chemical pumps for your industry:

Chemical compatibility

This is perhaps the most critical factor. Different pumps are designed to handle different types of chemicals, so it's essential to check the pump's compatibility with the specific chemicals you will be handling. Ensure the pump materials (such as casing, seals, and impeller) are resistant to corrosion and can withstand the chemical properties (e.G., acidity, alkalinity, viscosity) of the fluid.

Pump construction materials

Depending on the chemicals being pumped, materials such as stainless steel, plastic (e.G., polypropylene, pvdf), or alloys may be used. Select materials that offer the required chemical resistance and durability.

Flow rate and pressure requirements

Determine the flow rate and pressure required for your application. This will help narrow down the appropriate pump size and type (e.G., centrifugal pump, diaphragm pump) that can deliver the necessary performance.

Viscosity of the fluid

Dchemicals may have high viscosity, which can affect pump performance. Certain pump types, like gear pumps or peristaltic pumps, are better suited for handling viscous fluids compared to centrifugal pumps.

Temperature range

Consider the temperature range of the chemicals and the environment where the pump will operate. Ensure the pump can handle the maximum and minimum temperatures without compromising performance or safety.

Operational conditions

Assess factors such as suction lift (vertical distance between pump and fluid source), discharge head (pressure needed to move fluid to desired location), and any special installation requirements (e.G., submerged installation, explosion-proof environments).

Maintenance and serviceability

Evaluate ease of maintenance, availability of spare parts, and access to service support. Pumps that are easy to maintain can reduce downtime and operating costs.

Safety considerations

Ensure the pump design meets safety standards and regulations for handling chemicals. This includes features like leak detection, grounding capabilities (for handling flammable liquids), and safety certifications.
