How Variable Speed Makes Hydraulics Better

Fixed-speed motors spin at constant RPM regardless of demand, consuming excess energy during idle and partial load, producing unnecessary noise and heat. GHP’s variable-speed approach solves this by continuously matching motor speed—and therefore pump flow and torque—to real-time system needs.

The Hidden Cost of Fixed-Speed HPUs

  • Constant RPM means constant energy draw—even when flow demand is low

  • Excess energy turns into heat, raising fluid temperature and stressing components

  • High idle noise impacts operator comfort and safety

THE GHP APPROACH

The drive listens.

The motor responds.

The pump delivers only what the system needs.

  • Variable Frequency Drive:

    Adjusts motor RPM in real time based on demand

  • Smart Sensors:

    Pressure, temperature, and flow inputs feed control logic

  • Control Algorithms:

    Optimize speed/torque for stability and responsiveness

  • Hydraulic Integration:

    Delivers exact flow and pressure, reducing overconsumption and heat

    Energy:

    Demand-matched kWh and fewer peak demand charges

  • Green neon ear with sound waves emanating outward on a black background.

    Noise:

    Lower RPM at idle/partial load significantly reduces dB
