Wmp; Wmph - Maritime G6100 Operation Manual

Water Monitoring System

8.1.3 WMP

When inspecting the impeller pump, please note that wear and tear inside the pump is
normal due to the pump principle. The function of the pump will be OK until the wear and
tear inside the pump will result in the pump pressure and/or flow being too low to trigger
the flow sensor.
When this happens, the pump impeller and end cover will need to be replaced. Therefore,
it is recommended to always have an impeller, end cover, wear plates and shaft seal in
stock as spare parts.

8.1.4 WMPH

Check that the pump pressure is not unnecessarily high. High pressures will result in
reduced lifetime of the pump hose. Pressure recommendation: 0.8...2.0 bar. Pressure and
flow can be adjusted by means of the safety valve/pressure regulating valve in the WMPH
cabinet.
Check that the rollers and the hose are sufficiently lubricated. If the rollers and hose are
not sufficiently lubricated the lifetime of the pump hose will be reduced due to increased
friction heat.
Service of the gear is not necessary.
For hose replacement, refer to maintenance instruction MI6100-014.
It is recommended to always have spare parts in stock.
