Enerpac (A Division of Actuant Corp) has developed a special range of protected hydraulic tools designed for use in extreme environments.

The performance, reliability and lifespan of precision hydraulic tools such as hand pumps, cylinders and valves used for lifting, pulling, pushing, pressing, bolting, forming and fabricating structures, are impacted when exposed to extremely aggressive environments 

Even proven rugged technologies such as high-pressure (700 bar) hydraulics can be affected by exposure to moisture, chemicals, grit and grime, welding and high temperature environments encountered on demanding oil and gas, mining and energy, construction and infrastructure and primary processing sites.

Enerpac’s new range of protected hydraulic tools comprises of the compact but powerful high-pressure (700 bar) hydraulic pumps, cylinders and valves including nickel-plated steel cylinders with Viton seals, nickel-plated relief and check valves and anodised hand pumps. All these tools are compatible with the broader Enerpac range of hydraulic technology, which includes 700 bar hydraulic cylinders in hundreds of models with capacities from 5 to 1000 tonnes. 

Enerpac’s high temperature- and corrosion-resistant products include RC-V single-acting cylinders, P-142 ALSS and P-392 ALSS two-speed hand pumps and V66NV manual check valves. 

RC-V single-acting cylinders 

Available in capacities of 5-25 tons, stroke range of 54-158mm and weights from 1.5-10kg, the nickel-plated steel cylinders feature Viton seals providing heat and chemical resistance, while their plunger wipers reduce contamination and extend cylinder life. Where higher capacity-to-weight ratios are required, corrosion-resistant RAC aluminium cylinders are available up to 150 tonnes capacity and feature composite bearings on all moving surfaces to guarantee no metal-to-metal contact to resist side loads. 

Two-speed hand pumps 

Featuring a rapidly extending first stage to speed positioning of cylinder plungers, followed by a more powerful second stage to perform work in rugged or remote environments, the P-142 ALSS and P-392 ALSS hand pumps feature Viton seals, anodised aluminium pump reservoirs, plastic encapsulated pump bodies and stainless steel pump pistons and inserts that will not corrode or rust. Weighing just 2.1kg and 4.1kg respectively, the pumps have internal pressure relief valves for overload protection and handle locks for easy carrying. The larger pump has a second handle for two-hand use. 

V66NV manual check valves 

The manual check valves are provided for additional safety in load holding with cylinders and V-152NV pressure relief valves to limit pressures within hydraulic cylinders over a pre-selected adjustment range of 55-700 bar.
