2.2Pressure Accumulator

The purpose of the pressure accumulator, if installed, is to damp pulsation from the high-pressure pump and thus avoid vibrations in the discharge line. Gas in the pressure accumulator should be pretensioned to 50-60% of the maximum operating pressure. The correctly pretensioned gas must be checked regularly (approx. every 2 months – see separate operating instructions for pressure accumulator if necessary.)

3.Operation

Operation and Maintenance

·Check pump oil level and if necessary fill up (refer to specification information on page 8).

First oil change to be made after 50 hours of operation; thereafter oil must be changed every 500 operating hours – or at least every 6 months, whichever comes first.

Caution when operating in damp places or with high temperature fluctuations. Oil must be changed immediately, should condensate ( frothy oil) occur in the gear end.

·Before the high pressure pump is started, the centrifugal pump must produce the min. intake pressure of 36.0 PSI (2.5 Bar.)

·Open discharge line (e.g. spray gun) to enable booster pump to vent the system.

·Open all regulator valves and other shut-off agents.

·Activate bypass system or switch pressure regulating valve to bypass to enable pressure-free start.

·Start motor briefly to check the direction of rotation. Pay careful attention to the direction of rotation that is specified for the pump (arrows indicated on crankcase.) To serve this purpose, the pump must only be dry run for a short period (approx. 30 sec.).

·Start the pump and let it run in pressure-free bypass operation for approx. 2 minutes to enable the automatic functioning seal cooling system to vent itself.

Important! A small portion of water from the suction chamber which runs through the seal sleeves and steel elbow pipes is led off to pass behind the high-pressure seals to cool these.

As a result of heat dissipation, the elbow pipes are approx. 41-50° F (5-10°C) warmer than the water temperature on the suction side.

Important! Check regularly to ensure elbow pipes do not overheat.

If pipes become very hot (indication of seal wear,) stop pump immediately and examine seals and plungers (see maintenance section.)

·Listen carefully for an even running sound. If the pump begins to run irregularly or pulsate strongly, it can be that one of the three plungers is not vented. In this case, the pump should be started and stopped at quick intervals to ease venting. Venting is also made easier if the vent tap in the discharge line is opened.
