Can I use a DualPak with a Variable Frequency Drive?
Yes you can! No PRV or check valve is required because the check valve in the DualArm pump is utilized. We must ensure we use suction and discharge spool pieces in order to mount gauges and sensors. To price, use the Econo dualPak pricing, reduce the price by the price of the Constant Speed control panel from the HydroPak pricing, and add the Variable Speed control panel price.
