PRODUCT INFORMATION
RUGGED, ECONOMICAL TWIN STAGE SELF PRIMING PUMP
APPLICATION: Ideal for firefighting, tanker-to-tanker water transfer, high-head general water transfer, sheep jetting, irrigation and boom spraying.
FEATURES & BENEFITS
- Driven by either a Honda GX160 or a Honda GX200 engine which is specially designed for domestic or infrequent use. The GX200 engine is also available in electric start.
- Patented clamped impeller design to enable longer impeller life, improved performance and easier disassembly in the case of blockage.
- Twin impeller design provides extra strong pressure for longer and higher pumping applications.
- Thrust balanced impeller design to extend engine life
- Pump casing, diffusers and impellers manufactured from quality corrosion resistant marine grade aluminium for long life.
- Polyester coated pump casing, exterior and interior, for added corrosion resistance.
- Patented floating impeller neckrings front and back. The front neckring helps improve pumping efficiency, the back neckring helps extend seal life and dramatically reduce engine wear
- Self priming from 6m for more versatile installation options.
- Large priming and drain port with bayonet fit plugs. Plugs have safety retention system, plus are available with 1/4" tapping to accept pressure gauges or drain cocks.
- Low-oil protection on all models - engines won’t start or run if oil level is inadequate, thus protecting your engine.
- Electric start models have electric starter (battery and leads required) and recoil starter fitted , ensures a choice of starting methods, even if the battery is flat or removed.
- “HV” models come with Viton® seal, orings, gaskets, caps etc. fitted for improved chemical resistance. (Please seek specialist advice from chemical supplier if pumping chemicals. Use of aggressive chemicals may void warranty.)
- All engines conform to the tough environmental requirements of the USA EPA, CARB and the proposed Australian Emissions Standards, to help look after the environment.
*Only 5255H & 5265H are fitted with roll frames
