1. Isolate the pump from the electrical supply.
2. Close any shut-off valves in the suction and
discharge line to minimise product loss.
3. Place a tray (A) under the drain plug in the
bottom of the pumphead. The tray must be
large enough to contain the lubricant, possibly
contaminated with product fluid, from the
pumphead. Remove the drain plug (B). Catch
the lubricant from the pump housing in the tray.
Check that the breather mounted on the cover
is not obscured. Place back the drain plug and
tighten it.
4. Disconnect the suction and discharge lines.
5. Loosen the hose clamp (A) of the inlet and
outlet ports by loosening the bolt (B).
For the required quantity of lubricant, refer
to §
