Australian Pump Industries introduces Bertolini’s new CAX Series heavy
duty triplex pumps offering pressures up to 750 bar.
The new CAX Series from Bertolini combines a design breakthrough with value
for money performance. Key features of the 750-bar pump include flows up to 25
litres a minute at 1000 rpm; 316 stainless steel pump head providing great
strength to maximise chemical resistance in any high-pressure application; solid
pistons with tungsten carbide coating designed to reduce wear and prolong both
high and low pressure seal life; and high pressure seals made of PTFE and
energised component reducing friction to the minimum, thus ensuring perfect
hold in any condition for a longer period of time while providing chemical/ solvent
resistance and superior performance.
Large diameter stainless steel plunger rods are designed to avoid contact
with the oil seal, thereby reducing wear and ensuring sufficient lubrication of
the pistons. Premium bearings are designed to endure heavier loads and extend
“This is a breakthrough pump in terms of design and value for money,”
said Aussie Pumps chief engineer John Hales.
“They even have patented du-dry plunger rod bushings, PTFE coated, to
greatly reduce friction to provide smooth operation.”
The pumps also offer check valves made of a thicker stainless steel
material to withstand high pressure operations. They are fitted with an
aspheric sealing system to enhance the high fluid dynamic efficiency and maximise
“We see these as being a major breakthrough for Australian Pump as we
start using these pumps not only to replace far more expensive equivalents but
also to start building bigger machines in both diesel and electric
configurations,” said Hales.
Aussie Pumps is already receiving excellent leads from offshore
operations and dry docks right through the South Pacific.
