Pump Operation
1.14 The Whale Gulper pump uses a single
membrane to pump the water away. On the
suction stroke, water and debris are drawn in
through the inlet valve. With a chamber full of
water the pump discharges the water
through the two non-return valves on the
outlet. The two outlet valves protect the
pump against losing prime. The aggressive
flushing keeps the pump valves clear of
debris resulting in a pump which does not
require regular maintenance.
Unlike other pumps, the Whale Gulper has
the ability to run dry without causing damage
to the pump.
An additional advantage of the three
nonreturn valves in the pump head, is that no
smells can be passed back from the waste
stack into the shower area.
