A NEW series of heavy duty industrial ‘Big Berty’ Bertolini pumps designed for industrial and pressure blasting applications has been released by Australian Pump Industries .
Called the KTV series, the new range includes a series of engineering upgrades that add value to the product in terms of consumer benefits.
The pump is available in a series of configurations to 21L/min flow and 4350psi maximum pressure rating.
It features new technology in the form of a new ‘deep sealing'" valve system that provides a number of benefits.
The valves are matched to the pump providing it with increased stroke of 2.5mm and a heavy duty stainless steel 2mm thick poppet valve that enables the unit to operate at up to 4350psi.
Other benefits include an upgraded pump head with inlet connector changed to 1" to provide increased flow to the pump (and improved suction) as well as housing the new style deep sealing valve caps.
One of the major benefits of the new valve caps is they can be tightened with only 50 per cent of the torque previously applied and do not require Locktite. This makes servicing substantially easier.
The plunger rods are now fitted with female threaded M8 x 1.25 calibrated holes to provide improved screw engagement and improved rod security.
A new piston locking bolt, with 10mm length engagement of the screw thread on the plunger rod provide 15Nm of screwing/unscrewing friction.
The new pumps are designed to provide professional users in mining, contracting or heavy industry with improved performance and substantially longer operating life.
