Goulds Variable Speed Constant Pressure Booster Pump, 1HP, 230V

Model # 1AB2LB1035
The Aquavar ABII pump controller and complete booster package kits provide an economical answer for municipal and private water systems with low water pressure. Both domestic and light commercial above ground boosters can benefit. As water use increases, the controller changes pump speed to maintain pressure. Large supply tanks are eliminated and up to 50% of the energy required by a full speed pump is saved.
Pre-packaged system that includes:
  • pump/motor
  • pressure tank - Goulds V6P (2 gallons)
  • pressure transducer
  • manufactured tee (copper/brass)
  • pressure gauge
  • wiring with flexible conduit

Booster Pumps

When do I need a pressure reducing valve for my booster pump?

We recommend using a pressure reducing valve in most booster pump applications with incoming pressure to avoid over-pressurization of pipes and fixtures.  Most home plumbing fixtures are rated for no more 85 PSI, and increasing the water pressure above this greatly increases the possibility of damage and leaks.

By using a pressure reducing valve, we regulate the amount of pressure going in to the pump so the pressure won't become too high in the event your public water pressure spikes upward.
