Enerpac  have introduced the new generation air-over-hydraulic foot pump, which enables finer and safer control of tasks while completing jobs quickly. The 700 bar Enerpac XVARI XA hydraulic pump features high oil flow, with its rotating air motor and rotating two-stage pump element giving hydraulic delivery up to 50% higher than conventional pumps with linear motor and single piston.

This technology offers variable oil flow and fine metering for precise control. 700 bar Enerpac XVARI XA hydraulic pumps are coupled with ergonomic two-pedal control of advance and retract functions for time-efficient and safer hands-free operation with less operator fatigue and increased stability.

The XVARI technology allows users to control the amount of hydraulic oil flow in the pump’s advance and retract mode, giving fine control of the speed of operation of the single-acting hydraulic cylinder or tool that the pump is powering. This process control is especially valuable for jobs that require accurate load positioning, aligning and controlled descent.

According to Tony Cooper, the better control improves productivity, enhances process quality and makes the workplace safer. Enerpac also surpass tradition by applying a two pedal design: one for tool advance (introducing pressure) and one for tool retract (releasing pressure).

The pedals are depressed with the ball of the foot so the heel stays on the ground, with bodyweight resting on both legs during operation. This causes less fatigue and provides increased stability and better control over the degree of pressure and thus control on the pump. The pump can be optionally equipped with an integrated pressure gauge. The 8kg pump’s broad base area enhances its stability.

Enerpac market research showed many users wanted higher hydraulic delivery. The 700 bar Enerpac XVARI XA technology have applied for a patent. The 700 bar Enerpac XVARI XA hydraulic pump’s higher piston speeds result in a smooth oil flow compared with the pulsating oil flow of conventional technology. A closed oil reservoir prevents leakage and eliminates internal contamination from airborne particles.

The 700 bar XVARI XA hydraulic pump’s higher oil flow reduces the time required to extend the cylinder or tool and build up maximum pressure. (Outflow flow rates are 0.25 l/min at rated pressure, 2.0 l/min with no load, with a usable oil capacity of 1 litre and dynamic air pressure range of 2.1 to 8.6 bar).

Enerpac also developed a hydraulic release valve for the700 bar Enerpac XVARI XA hydraulic pump’s retracting function. This is accurately controlled by the released pedal. The further the pedal is pressed, the faster the hydraulic pressure reduces and the faster the cylinder or tool retracts. This feature results in much better control over retract functions (for example, when a load must be lowered slowly and in a controlled manner).

Following are the features of the 700 bar Enerpac XVARI XA hydraulic pumps:

  • Pedal lock function for its retract position
  • Ground screw for improved ATEX explosion safety
  • External adjustable pressure setting valve

Following are the accessories of the 700 bar Enerpac XVARI XA hydraulic pumps:

  • High quality hydraulic hoses
  • Pressure gauges
  • Pedal safety guard
  • Joy stick lever kit for manual operation
  • Hydraulic swivel connector
