DRG Pump Motors

DRG pump motors are designed for water supply, pressurisation, fire safety and industrial processes, built to low vibration, minimum noise and high energy efficiency criteria for uninterrupted, reliable operation. They cover 0.25 – 355 kW in IE3 / IE4 classes, suit horizontal and vertical pump applications, and ship from stock.

Low Vibration – Pump and System Protection

In pump applications, vibration from mechanical oscillation, coupling misalignment and hydraulic imbalance can cause serious failures. DRG pump motors minimise these risks:

  • Low vibration levels per ISO 10816 / ISO 20816
  • Precise dynamic rotor balance (G2.5 / G6.3)
  • CNC-machined shaft and bearing seats for high alignment accuracy
  • Rigid cast body for resonance and vibration damping
  • Low axial and radial deviation

This extends bearing life, reduces maintenance and protects pump equipment.

Minimum Noise – Acoustic Stability

At pump stations, noise is critical for operator comfort and the environment. DRG motors minimise noise:

  • Stator design optimised to reduce magnetic noise
  • Harmonic-reducing slot / pole geometry
  • High-quality bearings reducing mechanical noise
  • Acoustic stability from low vibration

High Efficiency – Energy Savings

Pump systems often run 24 hours a day, so energy consumption is critical.

  • IE3 and IE4 high-efficiency class
  • 100% copper winding technology
  • Optimised magnetic circuit
  • Low losses and low temperature rise → lower operating cost

Heavy-Duty Design

  • IP55 protection class (dust and water resistant)
  • Class F insulation (optional Class H)
  • S1 continuous duty
  • Suitable for humid and demanding environments

Wide Range and Compatibility

  • 0.25 kW – 355 kW power range
  • 2 / 4 / 6 pole options
  • B3, B5, B14 mounting types
  • Suitable for horizontal and vertical pump applications
  • Fast delivery from stock

Applications

  • Water pumps
  • Fire pumps
  • Booster systems
  • Wastewater and drainage pumps
