UK-based hydraulic tools company Hi-Force this month launched a range of three-speed hydraulic torque wrench pumps to the global market.

The Hi-Force TPA-series and TPE-series range of air- and electric-driven pumps complement the company’s existing range of bolting products, which provide effective and safe bolting solutions to a variety of industries, including power generation, mining, shipbuilding, construction, oil and gas.

Hi-Force’s research, development and design team, based at its manufacturing facility in Daventry, UK, have created this range of pumps with speed, reliability and versatility in mind.

The pumps’ high-speed three-stage design provides a faster flow at midrange pressure, enabling projects with demanding time constraints to be completed as safely and efficiently as possible.

Further, the pumps multi-outlet four-way design allows for up to four hydraulic torque wrenches to be used simultaneously providing an even compression of the critical leak-sealing gasket on flange joint connections.

An automatically activated oil cooling heat exchanger, which is fitted on all electric models as standard, cools the pump and the hydraulic fluid, extending the service life of the pumps.

The TPA air-operated models incorporate an exhaust radiator located inside the oil reservoir, which also helps keep oil temperature under control during high-use operations.

The compact and rigid roll frame provides protection for the pump and provides a convenient method of manoeuvring the pump on site. The lightweight aluminium reservoir, with a maximum capacity of 7 ℓ, makes the TPA and TPE range one of the lightest hydraulic torque wrench pumps available on the market.

Safety and Ease of Use
Hi-Force considered ease of use and safety throughout the entire design and manufacturing process, incorporating features, such as a 5 m pendant cable, which allows the operator to work from a safe distance away from the pump and the bolting application. The single-button operation of the pendant, allied to an emergency stop button, provides enhanced safety for operators when immediate release of pressure to the torque wrench is essential.

An adjustable pressure relief valve with locking nut, for setting the maximum system pressure, acts as an additional safety feature of the pump.

Further, user-friendly features of the TPA and TPE range include a glycerine-filled gauge as standard, which is conveniently located for ease of viewing. A digital gauge is also available as an optional extra, providing torque readings in Nm and lb/ft, as well as bar and psi.

The TPE range of electric torque wrench pumps is available in a choice of 12 models, all with a maximum working pressure of 700 bar/10 000 psi. Power supply options of 50 Hz and 60 Hz are available for both the 110 V and 240 V models. The TPA air-driven version of the pump requires a 7 bar air supply and all models are available with either an analogue or digital pressure gauge.

Both the TPA and TPE range of hydraulic torque wrench pumps are compatible for use with both the TWS-N square drive and TWH-N low-profile female hexagon design Hi-Force hydraulic torque wrenches.
