Hopkins EPU56 Electric Hydraulic Power Pack

Ordering Code: EPU56

The EPU56 3PH electrical powered hydraulic power pack has a variable flow of 0-56lpm. Primarily designed for the offshore industry, but in reality, many of these units have been sold into a wide range of applications other than just offshore. The unit was originally designed to run our complete range of Stanley, Spitznas and Hopkins underwater hydraulic tools but its deployment has not been limited to these tools only. As would be expected of a pack designed for offshore work it is built to last in the harshest of environments and meets all current regulations.

Electric Hydraulic Power Pack Information

This unit is powered by a very efficient 18.5Kw 3-phase, 4-pole electric motor running at 1470rpm/50Hz. The electric motor can be run from a 50 or 60Hz 3- phase supply with hydraulic pump size being altered (matched) to ensure correct flow is delivered. Start-up is controlled by a StarDelta starter unit which is fitted with a 5-pin 63A plug for easy connection to an extension lead (a mating socket half is supplied to assist with electrical connection). The starter unit includes a phase inverter sensor relay feature which prevents the motor from starting up in the wrong rotation. The electric motor and controls are IP66 rated

Facility is also provided for manoeuvring the unit with a fork lift truck via two fork channels at the base of the chassis plus there are fitting eye on the top of the frame.
