Variable Frequency Controller
Canned Sealless pumps are available with a variable frequency drive and pressure transducer in a completely assembled and tested unit. This arrangement allows the system to maintain a constant preset discharge pressure via closed loop control over pump motor speed and also eliminates costly and often troublesome pressure relief valves and their associated plumbing problems.

This package is particularly helpful to OEM manufacturers whose equipment is exported to countries utilizing 50 Hertz electrical supply systems. Variable frequency controllers are also available for customer applications where flow, temperature, or other variables need to be maintained.
