The customer requested the ability to have variable flow rates to various circuits as needed. The end use did not require any type of proportional control and the more costly components it would possibly require on top of their lack of comfortability with proportional control.
The answer was a electric motor/pump combination driven by a variable frequency drive (VFD) allowing the customer general flow adjustment without excess flow and the heat generated going back to the reservoir thru a relief valve. High pressure filtration was included to protect and clean the fluid as the skid would be used for several systems. The cart was placed on casters with a drip pan to allow for ease of movement throughout their plant as needed.
Another happy PSI of Florida customer!!!
