Bertolini RA series 500 bar triplex piston pumps

A range of cast 316 stainless steel high-pressure piston pumps, designed for both cleaning and industrial applications, has been manufactured by Idromeccanica Bertolini and released by Australian Pump Industries.

The pump range is suitable for general engineering, the mining industry and applications involving salt water. The pumps are widely used in high-pressure water blasters, drain cleaning equipment and for mine industrial processing applications.

The RAM series triplex pumps offer a wide range of flow pressure options. Maximum pressures of up to 500 bar (7300 psi) are available with maximum flows of up to 31 L/min. The pumps are all equipped with Bertolini’s ‘smart case’, a design that uses a rib system to release heat away from the pump, eliminating high pump temperatures. This makes them more energy efficient.

The pump heads are manufactured from 316 grade stainless steel with back sections proportionate to the flow required for that particular series. Piston bolts are also 316 stainless steel, with precision-machined ceramic pistons that provide efficiency and minimum friction.

The seals are designed for high temperatures, with stainless steel 316 intermediate rings, stainless steel 316 retainers and PTFE anti-extrusion rings.

The stainless steel 316 valve caps offer a design that prevents cap failure due to over-pressurisation. It does this by isolating the valve cap threads with a bottle seal O-ring.
