Aussie Auto-Prime dry prime dewatering pumps

Australian Pump Industries has launched its latest range of dry prime dewatering pumps. The range includes a 3, 4 and 6″ dewatering pump and is said to simplify the complex design of other manufacturers, making maintenance easier.

The Aussie Auto-Prime range delivers high efficiencies and good solids handling capabilities. It offers the ability to automatically re-prime from a completely dry state and is engineered to meet the requirements of professional contractors, miners, local government and quarry operators.

The robust pumps all include 316 stainless steel impellers and volutes. The front cases are high-grade SG400/12 cast iron. The back plates are constructed from 431 grade stainless steel. The pumps are fitted with a rugged ‘ball type’ check valve, with a polyurethane seat and ball that’s easy to replace.

The 6″ pump, the AP150, boasts flows to 7200 L/min. The 4″ version achieves a maximum head of 40 m (vertical lift). All models feature good self-priming characteristics with the ability to lift water up to 8.5 m. The compressor prime design means the user can dry prime the pump without any manual filling of the suction line or the use of a priming tank.

The design utilises a jet of compressed air that passes through the Venturi-type nozzle to evacuate air from the pump casing and suction line. This makes for fast and continuous priming even when the pump is operating in snore mode. This means users can ‘set and forget’ the pump for site dewatering.

The pumps’ Perkins water-cooled diesel engines are fitted with an electric auto-start and come with shutdown protection. The units come with an integrated fuel tank and corner tie-downs. All welding jobs are completed to IAW AS 1554.1 and the chassis is pressure tested to IAW AS 1692.
