Premium piston pump
A new Premium series of high pressure triplex pumps has been released by Australian Pump Industries. The heavy duty product incorporates a number of new features, many of them unique. The range varies from 250 bar ( 3,625 psi) to 500 bar ( 7,300 psi).
The manufacturer, Bertolini Pumps f rom Northern I taly, developed the product for severe service applications i n pressure cleaning, drain cleaning, dust suppression and i ndustrial processing.
“Bertolini’s continuous programme of functional i nnovation adds longevity, reliability and ease of service with a number of new features,” said Aussie Pump’s Operations Manager, Hamish Lorenz.
Called the ‘ R’ Premium series, the pumps feature forged brass heads and oversized forged steel crankshafts. The heads provide l ong, vir tually unlimited, operating l i fe. The steel crankshafts reduce f ric tion of the rods on the shaft and enhance the internal component cooling. Plunger rods are i n stainless steel Tennifer treated, offering superior surface strength, i ncreased resistance and reduced wear.
Bertolini has even redesigned the valve cap to prevent
loosening. They did this by incorporating a bottom sealing O- ring to prevent extrusion under pressure. This unique feature totally prevents water l eaks and extends l i fe.
White ceramic plungers of 99.5 percent aluminium ceramic are standard. Ceramic wears even better than tungsten i n this application. Other pump manufacturers use ceramiccoated pistons as a cost reduction, something Bertolini won’t do!
I n an original design move, the company engineers decided to incorporate the suction manifold inlet in the diecast aluminium crankcase. That entry of cool, low pressure water through the pump body increases the cooling effect on all the components within the pump. It provides longer life and quieter operation of backflow pressure seals since they always stay “wetted”. The three ceramic pistons used to displace high pressure water are bolted and prevents loosening.
Bertolini uses bronze con- rods in matched two piece pairs that are designed to distribute heavier loads with minimum fatigue and wear. Double V packings that are self-lubricating with a liquid recycling area to ensure seals stay wet in any condition, extending life and preventing overheating.
“Since we introduced Bertolini to the Australian market some 20 years ago we’ve seen the company’s technology ramp up dramatically,” said Lorenz. “They insist on European or American components and have not been tempted to go to Asia to reduce costs. They won’t compromise on quality but keep increasing their volume as the market recognises the value of the brand,” he said.
Australian Pump, Australia’s leading manufacturer of high pressure water blasters, hydro testers and drain cleaners has moved into the Premium range to ensure Australian consumers get access to the world’s best products.
“In Australia users call them ‘ Big Bertys’ because they tend to be bigger, weigh more and simply have more material in them than competitor brands. Bigger crankcases supplied mean more oil capacity and that equals cooler running,” said Lorenz.
Prices are highly competitive. Aussie Pumps have introduced a service exchange programme to change out other brands that have suffered premature failures. www.demm.co.nz/reader- enquiry #170223
