Let's address progressive cavity pumps (PC), which fit into the cheerful rotating displacement pump family. The PC pump is often maligned as the pump of last resort. However, the PC pump is an excellent choice as the fluid viscosity increases beyond the efficient range of centrifugal pumps.
It is also
beneficial in applications where the fluid is abrasive and/or shear sensitive.
In agricultural applications, the pump is used to move fruits or berries with
little to no harmful effects on the product.
What is a Progressive Cavity Pump?
A Progressive
Cavity Pump is a sort of positive displacement pump which comprises a rotor and
stator. The metal rotor drives the stator through the chain and starts to fill
the cavities with equivalent measures of liquid which then gets pushed through
the pump outlet. They are an exceptionally hearty siphoning framework that
guarantees maximum performance and dependability.
How Does a Progressive Cavity Pump Work?
The rotor inside the pump rotates inside the stator, as it turns, the cavities inside the stator are loaded up with the cycle media and are conveyed towards the pump outlet under tension. The pockets of liquid have a set volume that concludes the volumetric stream pace of the pump, this is directly relative to the rotational speed of the rotor and results in low degrees of shearing and next to zero heartbeats.
Progressive
Cavity Pump Advantages:
- Good for solids handling and can also handle air entrained, multiphase, and abrasive liquids
- Excellent choice for high viscosity applications
- Offer low net positive suction head required
- Excellent self-primer pump
- Do not vapor lock
- Offer high accuracy as a metering pump
- A given size/model of pump installation will handle a wide range of viscosities very well
- Reversible direction/ bi-directionally. The pump can be operated in either direction, and the suction becomes the discharge and vice versa
- Quiet operation
BEST APPLICATIONS
These pumps are
used in a great range of applications from wastewater treatment to oil, to food
and beverage. Here are only a couple of the applications where a progressive
cavity could be found:
- Slurry and sludge transfer
- Oils
- Beauty care products, creams, and lotions
- Paint, stain
- Adhesives
- Fruits and Vegetables
The progressive
cavity pump is ideal for many applications across a wide spectrum of
industries. Think it might be right for yours? Make sure you get the right pump
for the job by talking to an experienced Industrial pump manufacturer. If you need
help selecting the right pump for your application, ask Risansi about it! We
