Revolutionary new diesel driven pump from Gorman-Rupp

A new diesel driven, “Prime Aire” trash pump from Gorman-Rupp is now available from Authorised Australian distributor – Hydro Innovations. The new pump has a revolutionary new [Patent Pending] impeller design, which is said to be able to handle large solids while maintaining efficiency.

The pump is a 75mm x 75mm centrifugal unit which can deliver flows from 3 litres per second (l/s) through to 28 l/s, with heads to 40m. The pumps have a patent pending “stagger-wing” vortex impeller, which is designed to enable the pump to handle a 76mm spherical solid along with stringy materials such as rags. The difference between this impeller and other vortex impellers is its vastly improved efficiency and head capabilities.

The pump’s priming capability comes from Gorman-Rupp’s unique priming system which includes a compressor and venturi device “pulling” a vacuum through Gorman-Rupp’s own air separation chamber. This, combined with an over-sized, oil lubricated mechanical seal, allows pumps to prime reliably and to run dry continuously without damage.

Hydro Innovations advise that the PAV3B60C-3TNV70 is powered by a Yanmar liquid cooled diesel engine that is USA EPA certified to meet interim Tier IV emission standards. Standard “auto-start” control panels include safety shut-down switches for high liquid temperature and low oil pressure. They also include tachometer, voltmeter, hour meter, coolant temperature gauge, oil pressure gauge, manual/stop/auto key switch, 10 AMP push-button circuit-breaker, start-up warning delay, muffler with weather cap, and throttle control.

This is just one pump in Gorman-Rupp’s line of PA (prime assisted) pumps, with capabilities to 800 litres per second, and heads to 180 metres with other models within the range.

The units are available as open skid mount units or with acoustically rated canopies and can also be fitted to road register-able trailers. More information on diesel driven pumps can be obtained from Hydro Innovations on 02 9647 2700 or email on [email protected]
