Aquavar™ SPD Variable Speed Surface Pump Controller

Do you want to Simplify your Commercial Pumping System? Goulds Pumps “SPD” variable speed, constant pressure pump controller is designed for the professional pump installer. With application specific features and Goulds Pumps designed software, the SPD was developed specifically for commercial water boster systems. This variable speed controller goes beyond a “standard” drive, giving the pump professional a rugged design that is built for demanding conditions.

Typical Applications

• Irrigation → Irrigation applications use both submersible and surface pumps about equally. The Aquavar SPD can control surface centrifugal pumps up to 30 HP.

• Rural Water → Rural water districts often pump ground water from community wells with single pumps of less than 50 HP. Many have a single water tower, which limits system pressure during peak periods or at remote ends of the distribution system. The Aquavar SPD can automatically compensate for demand variations with surface boosters.

• Building Booster → Commercial buildings of less than ten stories may require supplemental pressure to offset what is provided by the municipal system either on a permanent basis, or during periods of peak demand.

• Municipal WTP → Water treatment plants use booster pumps for tank storage boosting, or chemical injection applications. The “SPD” provides a 4-20mA current signal based on speed control 0 – 60 Hz of the main booster.
