Goulds PumpSmart® PS75

Goulds PS75 VFD

Low Voltage Variable Frequency Drive

Designed as a technologically advanced system that provides integral soft-starting, protection against pump failure due to process upsets, and the ability to Right-Size your pump in one easy to use package. Process Control features include:

  • • Single Pump
  • • Multipump Constant Slave
  • • Secondary Protection
  • • PID Sleep Function



  • Since your pump is constantly reacting to process changes, using the PumpSmart PS75 in process control mode maximizes your energy savings and pumping effectiveness by regulating pump speed to meet current demand

  • Sensorless Vector motor control enables the PumpSmart PS75 to start your pump in a controlled fashion
    Limits current in-rush, helping to improve your utility metrics, and it also reduces the stress on your pump and pumping system by building pressure and flow smoothly
    Eliminates over pressure and water-hammer effects that are normally associated with across-the-line starting
    When stopping, the PumpSmart PS75 similarly prevents water-hammer caused by check-valves slamming shut

  • Power consumption is a significant portion of your plants operating cost, and oversized pumps and control valves are a major factor in this
    Right-Sizing allows you to electronically trim the performance of your pump, without sacrificing its ability to meet future demands
    Note: A 20% reduction in speed can result in a 50% reduction in power consumption

  • With the most advanced pump protection logic in the industry, the PumpSmart PS75 is continuously on guard against process upsets that can lead to premature pump failure
    The patent pending PumpSmart Torque-Based Pump Protection (TPP) can protect against dry-running, operation below minimum flow and run-out conditions without the need for external sensors

  • The PumpSmart PS75 qualifies for the PumpSmart 3-Year Reliability Challenge
