BASIC EQUIPMENT

The basic design of this high pressure pump includes a complete hydraulic drive unit with oil/air cooler, high pressure intensifier, and bleed down valve. The operating pressure  is controlled by proportional valve and continuously adjustable between 20 and 400 MPa. All hydraulic and high pressure components are mounted on a base frame and covered by a sound insulated housing. The electric control is installed inside a switch box attached to the basic frame of the pump.

OPTIMIZED HYDRAULIC SYSTEM
The hydraulic unit is characterized by highly dynamic controls. Use of a soft-switching hydraulic valve with specially designed control geometry guarantees extremely short switch-over times. Oil filtering and cooling take place via the axial piston pump of the hydraulic drive. The excellent oil quality this achieves has a positive influence on operational safety and the life expectancy of the whole hydraulic system.

OIL COOLING
Oil/air as well as oil/water cooler are available as standard and installed on the base frame inside the pump housing. If the ambient temperature is lower than 35°C, an air cooler may be used. This eliminates the entire cooling water requirements. For higher temperatures the water cooler is available. Cooling water flow is controlled via thermostat.

THE PRESSURE INTENSIFIER
The high pressure components in the intensifier are characterized by a long life expectancy. Besides the special steels developed specifically for this application, Thanks to the special design, the intensifier is easy to maintain. Wearing parts like seals and check valves can be replaced quickly and easily.

PRESSURE ADJUSTMENT
Electronic pressure adjustment via relief valve is standard. proportional valve is optional too. So the working pressure is adjustable at the operating panel directly at the pump or via external analog signal from 4 to 20mA.

BLEEDING VALVE
This pressure release valve is installed within the high pressure line of the pump.

On request, any flow, any diameter and any control way are available for your inquiry.
