Heavy-duty high pressure cleaners go hydraulic

Drill operators have asked for a portable pressure cleaner that is safer and can handle the most strenuous mobile plant cleaning applications.

“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,” Australian Pump Industries’ product manager Hamish Lorenz said. “Recently we have focused on the drilling industry, realising that hydraulics are intrinsically safer than electric and definitely more convenient than engine drive.”

The range, in Aussie Pumps’ new Blaster Blitz catalogue, includes machines from 3000 psi to 7300 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 boast advantages over petrol or diesel drive machines.

“For a start they are quiet, don’t blow fumes or exhaust and are inherently safe. Depending on the parent power supply, they have almost unlimited grunt compared to conventional engine drive systems,” Lorenz said.

System designers like the hydraulic idea because the product can be located in a key position without drive shafts, gearboxes, pulleys and belts used in conventional applications.

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,” Lorenz said. “Conveyor belts, dust suppression systems and hydro-demolition are natural applications for hydraulic drive high pressure systems. The operator can work remotely from the machine and that’s a huge advantage. It’s safer and can isolate the work station,” he said.

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

The company chose the Bertolini pumps for this application because the machines are designed for heavy-duty industrial applications. The ‘Big Berty’ range features slow speed 1450 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 while 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, drilling rigs and all types of earthmoving and mining equipment.

High pressure hose reels, rated up to 500 bar, are also available for the easy storage of long length hoses for in-field cleaning applications.

“We are working with big fleet plant owners on developing machines that are more user-friendly, safer and more efficient than conventional cleaning equipment by using the power of hydraulics,” said Lorenz.

Further information on the full range of hydraulic drives, including simple application and installation details, is available from Australian Pump Industries.
