Progressing cavity pumps (PCP) are often the choice when there is low suction pressure. It is mostly used when centrifugal pump fails to fill & pump. For a closer look at PCP, its features, design & benefits, visit http://www.liftingsolutionsinc.com/progressing-cavity-pumps-pcp

1. When to Use
a PC Pump

2. 'PC pump' is short for progressive cavity
pump, a pump that's used in many different
applications, often in industrial work
settings. One of the many benefits of using
these types of pumps over other positive
displacement pumps is that it's abrasion
resistant. Let's take a closer look at PC
pumps and their applications.

3. PC versus Centrifugal Pumps
Centrifugal pumps are a popular choice
because they're economical and will last when
used in applications where the fluid being
pumped is water-like, or has a low viscosity.
What's more is that centrifugal pumps are best
used when there's a fixed flow rate?

4. PC pumps, on the other hand, are great for
situations where the fluid being pumped has a
high viscosity. In fact, whereas a centrifugal
pump will work less efficiently, using more
energy, a PC pump works more efficiently and
uses less energy the more viscous the fluid.

5. Another benefit of the PC pump is that it
maintains its flow rate, even as the viscosity
increases, but it's also possible to vary the
flow, if desired. This means that PC pumps are
ideally suited for applications where the
viscosity of the fluid changes, but you need to
maintain the flow rate, and by the same token,
in environments where you need to adjust the
flow rate. You can vary the flow rate simply
by changing the speed of the pump.

6. PC pumps are also often the pump of choice
when there's low suction pressure, so when a
centrifugal pump fails to fill and pump, the PC
pump will succeed.

7. Applications with Abrasive Solids
Although PC pumps are well suited for use in
many different applications, perhaps its best
use is in applications where there are abrasive
solids. While most positive displacement
pumps can't pump solids for long because
their designs make them susceptible to wear, a
PC pump's rotor and stator design makes it
more resistant to abrasion.

8. What Sets this Pump Apart
What makes the PC pump better suited for
pumping abrasive materials is its design;
instead of sending the fluid around the outside
of a casing, it flows axially. What's more is
that the stator is rubber, meaning that solids
can move past the stator with abrading.
