Precision-engineered 4-inch bronze pump motor designed for light commercial and residential water duties. The compact 0.37 kW (approx. 0.5 HP) motor is optimized for 400–415 V three-phase supplies, delivering reliable continuous operation for pressure boosting, circulation, bore/well pumping and transfer tasks. This bronze construction provides enhanced corrosion resistance for freshwater and mildly aggressive environments while the close-coupled design keeps service simple and quick.

• Power: 0.37 kW (≈0.5 HP)
• Voltage: 400–415 V, three-phase (50 Hz typical)
• Size: 4" motor/pump diameter — ideal for narrow wells and compact installations
• Materials: bronze casing/impeller with stainless-steel shaft for strength and anti-corrosion performance
• Design benefits: compact footprint, low vibration, easy maintenance and long service life

Applications include domestic well supply, irrigation, small-scale agricultural transfer, HVAC circulation and light industrial water handling. The motor’s bronze wet-end and quality sealing options make it suitable where saline or slightly abrasive water may be encountered. Installation flexibility and interchangeable sizing make this unit a solid replacement option for many standard 4" pump systems.

Recommended accessories and options: motor protection (thermal/overload), vibration mounts, threaded/universal unions for quick service, and an appropriate starter or control box for safe three-phase operation. For compatibility with other 4" motor-pump assemblies, check flange/shaft dimensions and mechanical seal specifications before installation.
