Aussie’s new diesel pump delivers high pressure and flow

Australian Pump Industries has introduced a new diesel powered 4-inch
pump designed to deliver both high pressure and high flow. The new Aussie QPT405SLTD
pump uses twin impeller technology to deliver pressures in excess of 125 psi
and flows of up to 46,200 litres per hour.

The new Aussie diesel pumps combine this excellent performance with
user-friendly features such as the ability to self-prime from depths of 7
metres, eliminating the need for the operator to prime the entire suction line
in order to get liquid into the pump. Aussie’s ‘Quick Prime’ design enables the
pump to prime itself once the pump body is filled with water.

Key features of the new Aussie pump include a compact design; 3-way outlet
offering the operator a choice of using either one 4″ delivery line, or two 3″
lines; pump body manufactured from non-corrosive high-grade aluminium; twin
impellers made from heavy duty alloy castings operating within heavy duty
volute casings; twin silicon carbide mechanical seals faced for hard wear, even
in abrasive liquid applications; pump shaft made from high grade S45C steel
designed for long life, and all O’rings from NBR (Nitrile Buna Rubber); and a
Kohler air cooled diesel engine developing 12kW power at 3600 rpm.

Aussie Pumps Chief Engineer, John Hales says the new pump has been designed
like a tank. The Aussie Pump team worked with the Kohler team to apply their
425-2 engine and backed it up with a big 60L fuel tank mounted in the
heavy-duty steel base.

Featuring a ‘sled’ design, the skid mount is fitted as standard with an
integrated lifting bar that enables it to be easily moved around the farm or
site. The pump weighs in at only 245kg, or 325kg when fully packed for

The Aussie 4″ pump will prime in 20 seconds from low suction heads and
takes up to 2 minutes to prime from 5 or 6 metres. Performance highlights
include the ability to shift flows of up to 450 lpm at a 50m head, or around
300 lpm at 60m head.

Hales expects to see a lot of interest in this pump from firefighting
authorities as well.
