Gulper Toilet Pump
Ensure all relevant personnel read the points listed
below and that a copy is passed on to the end user.
Read the points listed below before installation and
use of equipment.
The Whale Gulper Toilet pump is designed to pump
macerated and non-macerated toilet waste without
blocking. It offers a reliable means of emptying
waste holding tanks overboard and may be used in
vacuum toilet systems.
Ensure pump inlet and outlet valves are assembled
in correct orientation (Fig.1). Check that valves are
properly seated and inner and outer valve housings
are tightened fully.
1. Mount the pump above the level of the holding
tank. If this is not possible, fit a service valve on the
holding tank side of the pump. This prevents waste
draining into the pump during maintenance.
2. Mount the pump horizontally.
3. Direction of flow can easily be altered by loosen-
ing the screws which hold the clamping rings.
Rotate the pump head to the required angle, check
direction of flow and re-tighten (Fig.2).
Note:
a) The pump is designed to work at a maximum
lift/head combination of 3m (10ft). This includes
height of pump above holding tank outlet and
distances from pump to the highest point in the
discharge line and distance of seacock discharge
below waterline.
b) As the holding tanks on most boats are installed
below the waterline it is essential that proper siphon
breaks (vented loops) are installed to prevent siphon-
ing water into the toilet by leakage past the suction
or discharge valves of the pump.
4. A typical installation is shown in (Fig.3).
5. Position the pump in a dry, ventilated area that
allows maintenance access. Fix the pump in
position by attaching the screws and washers provid-
ed through the rubber feet.
1. It is recommended to use 38mm

)
smooth
bore thick walled non-collapsing hose which is
designed to minimise the permeation of waste
system odours.
2. To reduce the likelihood of permeation of odours,
keep the hose runs as short and as straight as
possible. Avoid dips in the hose which will remain
“wet”. Sweep connections instead of elbows should
be used whenever possible.
3. Connect the inlet and outlet hose to the pump
ensuring the flow direction is correct (Fig.1). Two
stainless steel hose clamps should be used at each
connection.
4. Where appropriate the Whale Diverter Valve
(DV5606), which has been specifically designed to
handle toilet waste should be used.
5. Install seacocks, deck fittings, etc. as per
manufacturers recommendations.
6. Do not connect pump directly in line with a deck
pumpout fitting.
Note:
An in-line fuse assembly is already fitted. This is
to prevent serious damage in the event of system
blockages. Ensure valves, seacocks etc. are
fully open before operating the pump
.
1. Use recommended replacement fuse and correct
wire size (see specifications).
2. Connections for a typical holding tank pump out
system are shown inn Fig.4.
3. Connect the power cable to the spade terminals
on the pump using crimped on connectors. Note: the
pump is polarity sensitive and will not operate if
connected wrongly. Protect the cable where it runs
through holes or over sharp edges.
4. Wiring must comply with applicable electrical
standards.
1. The pump is rated for up to 40 minutes continuous
running.
Warning:- Pump motor casing can become hot. Avoid
prolonged contact.
2. Always fit correct fuse.
3. Unnecessary running will reduce the life of the
valves and diaphragm. Turn off the pump when
leaving the boat. If some power has to be
maintained install a dedicated pump switch (Fig.5).
4. Ensure valves are seacocks are open before
operating pump.
5. Do not flush paper towels or feminine hygiene
