?We?ve experienced huge sales growth of hydraulic drive pressure cleaners since the introduction of the product range with demand largely coming from the drilling and construction markets,? said Hamish Lorenz, Aussie Pumps? Product Manager. ?Recently we have focused on the drilling industry, realising that hydraulics are intrinsically safer than electric and definitely more convenient than engine drive,? he said.

The range, in Aussie Pump?s new Blaster Blitz catalogue, includes machines from 3,000 psi all the way through to 7,300 psi. With flows of up to 120 litres per minute, hydraulic drive blasters have all the features and benefits of a conventional pressure cleaner but come with a series of significant advantages over petrol or diesel drive machines.

Australian Pump has matched up ?Big Berty?Bertolini heavy duty triplex pumps from both the TTL and RA series with top quality Cassapa hydraulic motors. The combination provides a close coupled, compact high pressure water blaster kit that can be either mounted in a cabinet, or even installed in a trolley depending on the application.

?Hydraulic drive really lends itself to material processing applications where loads of power is available and the pump can be mounted remote from the control station,? said Lorenz.

All machines come with the Aussie ASP (Safety Protection) kit that includes an unloader, thermal dump and safety valve. The safety valve protects the operator and machine against excessive pressure spikes whilst the thermal dump protects against failure from excessive bypass running.

The company chose to go with big Bertolini pumps for this application because the machines are designed for heavy-duty industrial applications. The ?Big Berty?Bertolini range are slow speed 1,450 rpm pumps designed for long life and trouble- free operation.

All units feature an exclusive reinforced Teflon sealing system for long operational life and wear resistance. Highly polished solid ceramic plungers provide extended life in extreme duty applications. Oversized roller bearings are standard in all models. Stainless steel valves, designed specifically for each series, offer superior performance characteristics to conventional pumps. Pumps up to 350 bar feature forged brass pump heads whilst 500 bar pumps all come with 316 stainless steel pump heads as standard equipment.

Hydraulic drives specifically suit mobile applications, particularly hydro demolition, drain cleaning and trenchless excavation. When vehicle or machine mounted, they can run off a hydraulic system of the parent equipment. That makes them ideal for dust suppression pumps on tankers, for drilling rigs, and all types of earthmoving and mining equipment.
