New hydraulic pumps deliver 700 bar pressure

“OUR new lightweight Enerpac pumps are able to provide power to various 700 bar hydraulic cylinders, nut cutters and torque wrenches quickly and efficiently. E-Pulse pumps are able to operate hydraulic tools as fast as pumps with motors larger than 0.75 kW. These pumps are currently the only hydraulic torque wrench pumps on the market with intelligent auto-cycle functionality and are the only pumps available that allow an operator to vary the speed between 25% and 100% of full speed,” so says Chantelle Janse van Rensburg, Enerpac Product Manager – BMG.

“E-Pulse hydraulic electric pumps have an adjustable speed-dial which allows the operator to adjust the speed to suit the specific task, ensuring precise control of large and small hydraulic cylinders and nut cutters, as well as quick and safe completion of work.

“For bolting applications, the operator can set the pressure and operate the torque wrench pump in either ‘manual’ or ‘auto-cycle’ mode. The intelligent auto-cycle function enables press-and-release actuation to the cycle wrench until final torque is achieved, significantly improving completion speed in every application.”

Th E-pulse range features a new interactive pendant that delivers visual and tactile feedback, as well as programming and diagnostic status to the operator. The IP 67-rated pendant, with protection against the ingress of dust and water, can be stored in the handle of the pump and is secured via a magnet. Operation, programming and diagnostics status are communicated to the operator through yellow, green, and red light emitting diodes (LED) as well as vibration pulses. Fault-codes indicate any issues related to voltage, temperature and button malfunction, or if professional service is required.

The new E series pump range is a high-performance pump, with an 63 kW direct-drive motor, has a six-piston block design that provides even-flow and smooth operation of connected tools. Various models are available from BMG, with a choice of five valves – 3/2 jog, 4/3 jog, 3/2 dump-and-hold, 3/2 dump and 4/2 torque wrench. Flow at rated pressure is 32 in 3/minute, with a maximum operating pressure of 700 bar.

Additional features include a 24 V DC power regulator, built-in thermal protection, a 6 m pendant cord on the torque wrench pump and a 3 m pendant cord on the other four pumps. All models in this range are fitted with a convenient cord management system.
