Goulds Constant Pressure Systems

The Balanced Flow is a variable speed, constant pressure controller designed exclusively for submersible well pumps.  It provides smooth control for residential submersible water systems which typically uses a larger tank and switch.  The controller monitors the pressure in the system and adjusts the pump speed to maintain a constant pressure.  The Balanced Flow also monitors the motor current draw, voltage, temperature, and loss of pressure.  It's design is simple and rugged.

The Gould ProPak has several advantages over a traditional submersible pump system:

  • City-like water pressure at every faucet no matter the demand
  • Lower electricity usage by 50% due to the controller converting single phase input to 3 phase
  • 0-100 PSI Pressure Setting with finger controlled adjustments
  • Only a small inline pressure tank is needed, no large bulky floor stand models are required
  • Wall mounted controller saves space and is Nema 3 rated and can be mounted outside
  • Designed for continuous operation:  Ideal for larger homes, irrigation systems, tight installation clearance issues, and geothermal applications.
  • High quality Goulds GS stainless steel pump with sand and abrasion resistant design
  • Self Diagnostic Controls check for Dry Well Ground Fault, Short Circuit Disconnected Lead, High Pressure Sensor, Temperature Fault
  • Smaller gauge wire is required

Goulds ProPak Kit include:

  • CentriPro Three Phase Motor 1.5 – 5 HP, 230 V
  • CentriPro Aquavar SOLO™ Controller with Transducer
  • Goulds Pumps GS Water End (pump)
