Progressive cavity pumps also known as positive displacement pumps, cavity pumps, PC pumps, and PCP pumps. To deal with unknown variables, some people frequently purchase bigger pumps, which ultimately results in more expensive equipment, components, servicing, and operating costs.
The process of choosing the ideal progressive cavity pump
model is a little complicated. Similar queries may come up frequently among
consumers before they choose the best model for their pumping applications.
Progressive cavity pumps work well with some
materials and applications. They are not, however, the best option for every
application, which is generally true of many different types of pumps. Picking
the right pump is always important. To achieve the best results for your fluid
processing application, you must locate, configure, and run the proper pump
system.
The following ten items must be ready for your pump
manufacturer or distributor before you purchase the PC pump.
What type of
substance needs to be pumped? type: dry solids or viscosity?
The maximum speed permitted, the maximum pressure per
stator/rotor stage, and the pump slip all decrease with increasing viscosity.
Are there any
solid components present? What are the highest solid concentrations and
particle sizes?
Because abrasive soft solids limit the maximum permitted
pump speeds. Pumps need to have large enough cavities to pass the material's
largest hard particle. Knowing the solids' concentration is preferable to
knowing their particle size. Most products demonstrate their viscosity
characteristics due to the high volumetric content of finely divided materials
in suspension, such as toothpaste, paper-coating mixes, etc. Combined liquids
and microscopic solids typically generate a non-Neutonian liquid. The maximum
permitted speed and pressure per stage are reduced as the number of solids in
suspension increases.
What is the
maximum temperature of the substance?
The selection of elastomeric materials for the pump stator
is impacted by higher temperatures. Moreover, using smaller rotors is necessary
at higher temperatures.
The pressure is
what?
Pump slip increases as differential pressure rises; higher
pressures call for more stator/rotor stages; The rate of abrasive wear is
accelerated by higher pressures and slide.
What is the pH
level?
An alkaline pH ranges from 7 to 14, while neutral pH ranges from 0 to 7. To choose appropriate building materials for the pump, you should be aware of the pH value (hydrogenation activity) of the material.
Conclusion
Following the principles of economy, logic, and
dependability should guide the precise selection of a single progressive cavity
pump. If the model choice is poorly thought out, it will cause issues with
management, upkeep, and future use. So, choosing a reasonable and trustworthy
PC pump to the actual requirements for production may not only assure smooth
production but also lower the costs of management and maintenance in the
future. For instance, it can lower the frequency and scope of your general
accessory repairs and replacements.
If in doubt, consult with the top manufacturer and supplier. Risansi Industries Ltd. is the best company that offers progressive cavity pumps, and will also guide you with the best selection, thus ensuring efficiency and reliability.
