Installation, Maintenance and

Operating Instructions

for hp- internal gear pumps

Series UHE-AX

Please adhere to the following points during installation and prior to initial start-up:

1. The pump will not start up when dry. First fill it with oil.

2. Assure that all pipelines are free of dirt and soil. Suction lines must be bled via the
manometer connection on the delivery side - particularly when long suction lines are being used.

3. Make sure that the pump rotates in the direction designated by the arrow.

4. Shut the solenoid valves before setting or resetting the pump pressure.

5. When installing the pump, make sure that you align the pump shaft and the primary shaft
precisely and that the shafts are not exposed to any radial pressure. Also be sure to use a
clutch that corresponds in terms of size and weight to the pump shaft and that does not convey
any balance error to the pump. To avoid any damage to the clutch, be sure not to hit or bump
the pump shaft, either directly or indirectly, during clutch assembly.

6. There must be 1 to 1.5 mm of clearance space between the two halves of the clutch. Make
sure that the rotating clutch parts do not touch or rub against any of the stationary pump or
motor parts (axially)!

7. Check that all pipe connections and lines have been connected tension-free and are properly sealed
and absolutely tight. We recommend the use of seals made of either copper, aluminium or
synthetics. Under no circumstances may you use hemp, hemp-like materials or any material
similar thereto!
