Abstract
The submersible water pump comprises a pump body (1) having a water inlet (23), water outlet and a water passage (11, 12, 13) between the inlet and outley. Water from the inlet is pumped through the passage to the outlet. The pump comprises a visual indicator (18) on the pump body for indicating the water flow rate through the pump. The visual indicator comprises a member (18) which is linearly movable in response to changes in the water flow rate through the pump to provide an indication of such water flow rate. The linearly movable member (18) is contained in a portion (11) of the passage which is made of a clear material visible from the exterior of the pump.
