HLP Pumps Installation Tips

Initial Installation

be aware that the pumps are supplied filled with fresh water to ensure that the hydrostatic bearings are kept full of water. This should be thrown away at time of installation.

You have been warned and do not blame us when you take off the cap whilst sitting on your sofa at home and get a wet lap - it happens.

Isolation

All models of HLP should be installed with a shut off valve either side of the pump to allow bleeding of the pump and to allow isolation for removal and cleaning.

Shut off valves should be sized so that the bore of the valve is the same as the outlet/inlet of the pump which generally means one size bigger.
