Useful information on centrifugal pumps

With high viscosity feeds, centrifugal pumps become increasingly inefficient: there is greater resistance and a higher pressure is needed to maintain a specific flow rate. In general, centrifugal pumps are therefore suited to low pressure, high capacity, pumping appli ions of liquids with viscosities between 0.1 and 200 cP.

Centrifugal pump system tips, do& 39;s and dont& 39;s

In residential systems, the pressure switch shuts the pump down when the pressure is high which means there is low or no flow. 3. Use pressure gauges. Make sure your pump has a pressure gauge on the discharge side close to the outlet of the pump this will help you diagnose pump system problems.

Closed Loop Systems - FluidFlow FluidFlow

Closed Loop Systems February 13, 2018 James McLoone. In general, there are two main types of systems in which pumps can be installed, open-loop and closed loop systems. Open-loop systems are circuits in which the pumped fluid is exposed to the local atmosphere at some point in the circuit.
