Positive displacement pumps, cavity pumps, PC pumps, and PCP
pumps are other names for progressive cavity
pumps. Some individuals usually buy larger pumps to deal with unknown
variables, which ultimately leads to more expensive equipment,
components, servicing, and operating costs.
Selecting the best progressive cavity pump model is a
somewhat involved task. Customers may ask such questions a lot before deciding
which model is suitable for their pumping needs.
Certain materials and uses are well-suited for progressive
cavity pumps. As is typically the case with many various kinds of pumps, they
are not the best choice for every application. Selecting the appropriate pump
is always crucial. Locate, set up, and execute the fluid processing
application to get the best results.
Before you buy the PC pump, the following ten
things need to be prepared for your pump distributor or
manufacturer.
What kind of material has
to be pumped? type: viscosity or dry solids?
As viscosity increases, so do the maximum allowed speed, the
maximum pressure allowed per stator/rotor stage, and the pump slip.
Are there any solid
components? Which solid concentrations and particle sizes are the highest?
as the highest pump speeds that are allowed are
restricted by abrasive soft
solids. The largest hard particle in the substance must be
able to pass through the cavities of the pumps. It is better to know the
concentration of the solids than their particle size. The majority
of goods, like toothpaste and paper-coating mixtures, exhibit their
viscosity characteristics because of the high volumetric concentration of
finely divided components in suspension.
What is the substance's
maximum temperature?
Higher temperatures affect the use of elastomeric materials
for the pump stator. Moreover, at greater temperatures, smaller rotors are
required.
What is the pressure?
Greater pressures require additional stator/rotor
stages; pump slip increases as differential pressure
rises; greater pressures and slide accelerate the rate of
abrasive wear.
What is the pH value?
Neutral pH varies from 0 to 7, and alkaline pH extends from
7 to 14. You must consider the material's pH value and hydrogenation activity
when selecting construction materials for the pump.
In summary
The exact selection of a single progressive cavity pump
should be based on the principles of economy, logic, and
reliability. A poorly considered model selection will lead to problems
with maintenance, management, and future use. Therefore, selecting an
appropriate and reliable PC pump based on the actual production requirements
may help to ensure efficient production while also reducing
future administration and maintenance expenses. For example, it can reduce
the number and extent of general accessory replacements and repairs.
When in doubt, seek advice from the leading source and
manufacturer. The greatest provider of progressive cavity pumps is
Risansi Industries Ltd.; they will also help you make the finest decisions and
guarantee dependability and effectiveness.
Risansi also deals in other types of pumps like single screw
pumps, barrel pumps,
and more throughout India and across the globe.
