4. Application
The Gulper® Grouper diaphragm pump has been designed to pump water and small solids from a sh box overboard
or to a holding tank. If it is intended for use for any other purpose or with any other liquid, it is the user’s responsibility
to ensure that the pump is suitable for the intended use and, in particular, that the materials are fully compatible with
the liquids to be used.
5. Warnings
1. This pump must not be mounted below the water line when connected to an intake or outlet
unless the system has a vented loop.
2. Not suitable for pumping ammable liquids, diesel, chemicals etc.
3. With all applications, it is important that a system of safe working practice is applied to
installation, use and maintenance. Electric supply must be turned off and waste water system
is drained prior to installation.
4. In order to securely fasten the unit, ensure that the mounting surface is a minimum thickness of 19mm (3/4”)
(when tted with the screws supplied).

5. NOTE Do not screw directly to the hull - the pump must be mounted on a bulkhead or on an additional board.
6. NOTE Do not unscrew the rear section, as interference with the internal electrics will render the pump unt
for use and invalidate the warranty. This is a non-serviceable part of the pump.
7. WARNING: Fire hazard. Wiring must comply with applicable electrical standards and include a properly rated
fuse or circuit breaker (see section 7) Improper wiring can cause a re resulting in injury or death. Switch off
the power while making connections.
Suggested wiring information is given as a guide only. For full information, refer to the USCG, ABYC and ISO
regulations for marine applications and wiring gauges, connectors and fuse protection.

6. Installation
Note: Incorrect installation will invalidate warranty.
Preparation - Always disconnect power sources before installing.
6.i Location
• Choose a position to mount the pump that is dry and away from standing water.
• The pump may be mounted on a horizontal or vertical surface.
• When mounted vertically ensure that the pump head is lower than the pump body (see Fig 1).
Figure 1 - Pump Orientation Figure 2 - Typical Installation
6.ii Mounting Instructions
• The Whale® Gulper® Grouper pump must be installed at or below the level of the sh box drain (Fig 2). The
opening for the shbox drain must include a grid. with openings no greater than 19mm x 19mm.
• The pump must not be mounted below the water line when connected to an intake or outlet unless the
system has a vented loop (Fig 2).
• When mounting, position the pump on the intended surface. Then mark the 4 hole positions using the pump
feet.
NOTE: The pump head may be rotated to suit the hose connections. This is achieved
by loosening the screw which holds the clamping ring and rotating the pump
head. (Fig 4)
• Once the position for the four mounting feet is marked, drill four pilot holes of
3.2mm(1/8”). Use four No.8 self-tappers and washers to secure the pump.
NOTE: Do not screw directly into the hull, mount the pump on a bulkhead or
additional board.
6.iii Inlet and Outlet Valves
• Inspect and ensure that the tricuspid valves are seated in both inlet and outlet
ports.
NOTE: The inlet valve must point with the triangular part pointed into the pump and
the outlet valve with the triangular part pointing towards the hose. (Fig 3)
• Install ports on the pump head.
• The retail Gulper Grouper (BP4772 / BP4774) contains, 2 x 25mm (1”) ports
and 2 x 38mm (1 ½”) ports are supplied to suit your installation. For optimum
performance, Whale recommend using a 38mm (1 ½”) port on the inlet and
25mm (1”) port on the outlet connected with reinforced hose.

8. Maintenance
NOTE If you are not familiar with applicable electrical standards, ensure that the unit is installed by a qualied
electrician / technician.
WARNING: Fire hazard. Wiring must comply with applicable electrical standards and include a properly rated fuse or
circuit breaker. Improper wiring can cause a re resulting in injury or death.
NOTE Switch off the power prior to making connections. Suggested wiring information is given as a guide only. For full
information, refer to the USCG, ABYC and ISO regulations for marine applications and wiring gauges, connectors and
fuse protection.
• The polarity is indicated by coloured cable
(Positive: red, Negative: black).
• The pump is protected against reverse polarity
connection when the fuse is correctly rated
• Minimum wire size is to be 1.5mm² or 16 AWG.
NOTE Undersized wire reduces voltage under load at the
pump, thus giving poor performance and potential motor
failure.
• To control the pump, an in-line switch should
be tted between the positive live terminal on
the battery and the positive lead on the pump.
If using an automatic switch (such as a oat
switch) an isolator switch must also be tted.
Circuit Breaker / In-Line Fuse Assembly:
The purpose of this fuse is to protect the pump from serious damage in the event of system blockages, therefore
please ensure all valves are fully open before operating the pump.
1. If the circuit breaker trips, or the fuse blows, check:
a) All system valves / stop cocks are open (if installed).
b) The inlet and outlet ports are not blocked.
c) The remainder of the system is not blocked in anyway.
2. For 12 V d.c. models, use a 10 Amp automotive fuse. For 24 V d.c. models, use a 5 Amp automotive fuse.
This Whale® Gulper® Grouper Mk 3 is designed to only require minimal maintenance.
WARNING: Before servicing pump, turn off pump and drain water from system. Ensure that the pump is disconnected
from electrics and plumbing during maintenance.
Optimal Performance
• Ensure this product is clear of debris and ush with clean water after each use.
• Check / tighten hose clamps on elbow connections once per season.
Annual checks
• Whale advise that the boat’s plumbing system is checked annually for leaks and obstructions. An annual
pump electrics check is also recommended and must be conducted by a qualied electrician.
To inspect or replace the diaphragm, the user must rstly remove the pump head clamping ring. This is done by
unscrewing the clamping screw (Fig 4). This will release the pump head, and allow easy access to the diaphragm.
• If diaphragm shows signs of wear, damage or cracks it should be replaced (using Service Kit AK1557). If the
diaphragm needs replaced, undo the nut in the centre of the diaphragm and remove the diaphragm plate and
diaphragm (Fig 5).
NOTE The centre pin may be in one of several positions; (this will not affect replacement of the diaphragm).
• When replacing, the diaphragm can be tted either cup up or down.

• Ret the clamping plate making sure the rounded outside edge faces the diaphragm, also ensure that the
outer sealing edge of the diaphragm is located securely in the grooves between the body and gear housing
(failure to do this will cause the pump NOT to prime).
• Ret clamping rings and tighten screws.
To inspect or replace the tricuspid valve(s), unscrew either or both housings to expose the valve(s). If a valve shows
signs of wear or damage, replace and re-assemble housings ensuring that the valves and diaphragm remain correctly
seated.
