Learning About Non-Metallic Pumps

The term “non-metallic pump” refers to a particular kind of pump made of materials other than metal, such as plastic or fibreglass. These pumps are made to handle fluids that can corrode or harm metal pumps, such as those that are extremely reactive. A non-metallic pump manufacturer is crucial to offering dependable and affordable pumping solutions for a variety of sectors.

Pumps Made Using Non-Metallic Materials

Non-metallic pumps come in a variety of varieties with different uses on the market. A few popular non-metallic pump types are listed below:

Centreless Pumps Made Of Plastic

Materials like PVC, CPVC, and polypropylene, which are thermoplastics, are used to make these pumps. Acids, alkalis, and chemicals are frequently moved around with them.

Magnet-Driven Pumps

For these pumps, a mechanical seal is not necessary because a magnetic coupling is used to transfer power from the motor to the impeller. For moving potentially dangerous or corrosive fluids, they are perfect.

Pumps With Two Diaphragms

In order to provide suction and discharge, these pumps oscillate a diaphragm using compressed air. They are frequently employed for pumping and transporting abrasive, viscous, or shear-sensitive fluids.

Pumps with Peristalsis

Flexible tubes and rollers are used in these pumps to provide a squeezing action that propels the fluid through the tube. They are perfect for measuring exact volumes of fluid and handling shear-sensitive fluids.

Adaptive Cavity Pumps

To transfer fluid through the pump, these pumps include a revolving stator that resembles a screw. Sludge, slurries, and viscous fluids are commonly handled by them.

Pumps Made Of Fiber-reinforced Plastic (FRP)

These pumps are constructed of fiberglass and resin, making them corrosion-resistant and perfect for handling corrosive fluids. They are frequently employed in the petrochemical, chemical, and wastewater treatment sectors.

Procedure for Non-Metallic Pumps

Different techniques are used by non-metallic pumps to transfer fluids from one location to another. Depending on the kind of pump being used, a non-metallic pump will operate in a particular way. Non-metallic pumps operate according to the following broad principles:

Good Displacement

A fixed amount of fluid is moved with each cycle by positive displacement pumps using a mechanical process. Diaphragm pumps, rotary pumps, and piston pumps are a few types of positive displacement pumps.

Centrifugal Force

The fluid is pushed out of centrifugal pumps by a centrifugal force produced by a revolving impeller. The liquid enters the pump at the center and is driven out to the pump’s edge by the impeller’s vanes.

A diaphragm is moved back and forth by compressed air in air-operated diaphragm pumps to produce suction and discharge. The fluid is forced through the pump as a result of the diaphragm’s back-and-forth motion.

Action of Squeezing

Flexible tubes and rollers are used in piston pumps to provide a squeezing motion that propels the fluid through the tube. The rollers compress the tube, creating a vacuum that pulls fluid into the tube. Then let the vacuum out, pushing the fluid through the tube.

Coupling with Magnets

Mechanical seals are not required in magnetic drive pumps since the power is transferred from the motor to the impeller via a magnetic connection. The fluid is rotated by the impeller’s magnetic field. It is driven by the magnetic field of the motor.

Conclusion

Chemical processing, medicines, food and beverage manufacturing and semiconductor manufacturing are just a few industries that frequently use non-metallic pumps. They are renowned for their low maintenance needs, durability, and corrosion resistance.
