FEATURES

  • The pump is driven through an Interpump Group RS500 reduction gearbox operating at approximately 1450 RPM. Lower pump operating speed reduces mechanical load, heat generation, and operating stress during prolonged cleaning work. This configuration is specified for professional applications involving sustained operating periods and extended duty cycles.
  • Powered by a commercial-grade Yanmar L70V air-cooled direct injection diesel engine specified for professional equipment applications. The L70V platform is widely used across industrial and agricultural machinery where fuel efficiency, long operating life, and diesel-powered operation are required.
  • Fitted with an Interpump Group 59 Series triplex plunger pump configured for professional pressure cleaning applications. The triplex pump design uses serviceable internal components and separate ceramic plungers to support consistent pressure delivery and long-term maintenanceability.
  • Return-to-tank bypass configuration helps reduce heat build-up during trigger-off operation by recirculating bypass water back to the supply tank rather than through the pump manifold.
  • Low-pressure downstream chemical injector enabling detergent application through the outlet circuit. The injector operates on the low-pressure side of the pump system, reducing chemical exposure within the high-pressure pump manifold.
  • Integrated priming valve fitted to the pump manifold assisting pump priming when operating from suction-fed water supplies. The system supports improved water supply stabilisation during initial startup and reduces priming difficulty when drawing from static water sources such as tanks or bowsers.
  • Heavy-duty powder-coated trolley chassis fitted with 13-inch transport wheels for movement across uneven professional working environments. The larger wheel configuration improves manoeuvrability during transport across rough ground, agricultural yards, and commercial site conditions.
  • Each machine is assembled, calibrated, and pressure-tested in the United Kingdom prior to dispatch. Final inspection includes operating verification, pressure confirmation, and general assembly checks before shipment.

PRODUCT OVERVIEW

The GTD-150HD is a gearbox-driven diesel pressure washer specified for professional cleaning applications requiring prolonged operating periods, thermal stability, and reduced pump operating speeds compared to direct-drive systems.
Powered by a Yanmar L70V direct injection diesel engine and Interpump triplex pump system, the GTD-150HD is configured for agricultural, commercial, and industrial cleaning environments where durability, serviceability, and continuous-duty performance are prioritised.
The reduction gearbox system operates the pump at approximately 1450 RPM, reducing heat generation and mechanical stress during extended operation. Combined with the return-to-tank bypass configuration, this supports improved thermal control during trigger-off operation and prolonged cleaning periods.
An integrated easy-prime valve assists priming from suction-fed water supplies including tanks and IBC systems, making the machine suitable for mobile and remote cleaning applications where mains-fed water supplies may not be available.
Mounted on a heavy-duty powder-coated trolley chassis with 13" wheels, each GTD-150HD is assembled, calibrated, and pressure-tested in the United Kingdom prior to dispatch.
