Typical applications
Viking Power 32/Vacuum is the ideal dia-
phragm pump for toilet drain, wastewater
and bilge pumping. Its compact design
gives a very adaptable mounting and instal-
lation in the boat. Viking Power Vacuum
has a large self-priming capability and is
very suitable for installation in a vacuum
system.

Working principle
Single-chamber, self-priming diaphragm
pump. To obtain good self-priming ability
and a filter-less solution, the pump is
designed with a large single diaphragm
and a long stroke. This way a lot of water
is pushed through the pump house in each
stroke and any debris is flushed through
(compare rubber sink cleaner)

Installation and maintenance
Installation
• Mount the pump in a dry location.
• If the pump is mounted vertically, the
motor must be above the pump house.
• Mark screw positions and drill pilot
holes.
• Mount the pump using stainless steel
screws and the enclosed washers. Make
sure that the plastic spacers are in their
correct position. NOTE: Take care not
to fasten the vibration-damping rubber
feet too much.
• Mount the outlet anti-drainback valves
and screw the connections - Viking
Power Vacuum.
NOTE: The anti-drainback valves are
mounted with the pointed end towards
the flow direction. See the drawing.
• Reinforced flexible tubing is recom-
mended.
• Use stainless steel hose clamps to secure
tubing to connections and other hose
barbs in the system.
Electrical installation
The pump must be installed according to
ISO 10133 (Small craft – Electrical system
– Extra low voltage DC installation).
NOTE: The fuse must be ignition protec-
ted.
The motor is equipped with built-in
thermal protection to prevent overheating.
The protection is automatically restored
when the motor is cooled. See the wiring
diagram for correct installation. Negative
wire must be black.
Choose wire size in accordance with total
wire length (see table). The wire connec-
tions must be sealed with a marine sealant.
NOTE: Before installation with electrical
control systems, check that equipment to
be used is of sufficient rated capacity to ac-
cept amperage draw of motor. Low voltage
can cause the motor to overheat.
Maintenance
The pump valves inside the pump house
should be regularly cleared from debris to
prevent reduced performance and poor
self priming capability. This is done by
unscrewing the house clamp and opening
the house. The outlet
anti-drainback valves are located above
the connections. (Viking Power Vacuum.)
NOTE: Make sure the pump is disconnec-
ted from the power supply.
Wiring diagram
Other electrical devices such as circuit brea-
ker and relays must be installed between the
pulp and the positive (+) lead on the battery
(on the red wire).

Self-priming
The pump is self-priming up to 2,5 and 5 m
respectively (Viking Power Vacuum)
Dry running
The pump can be run dry without any
harm. It will however unnecessary reduce
your battery power.
Hand cranked power
The pump can in case of emer-
gency such as power failure be
run with the enclosed hand-
cranked power source.
NOTE: Make sure that the
pump is disconnected from the
power supply while the motor is working
as a power generator.
NOTE: Do not run the pump with power
supply and the crank mounted at the same
time.
Winterizing
Drain the pump from water by pumping
it until it primes air and there is no fluid
coming from the outlet.

and check for damage.
There is a risk of damage
if a frozen pump/motor
is started.
2. The pump does not prime. 2.1 The water tank is empty. 2.1.1 Fill up the tank.
2.2 Debris under/in the valves. 2.2.1 Open the pump by body
by unscrewing the two
screws and clean the
valves. Clean the outlet
valves. (Viking Power
Vacuum.)
2.3 Perforated diaphragm. 2.3.1 Replace the diaphragm.
2.4 Leak on inlet side of pump. 2.4.1 Check tightness of hose
connections.
2.5 Inlet or outlet plumbing 2.5.1 Check the plumbing and
restricted. the valves.
3. Low flow/pressure. 3.1 Lean on outlet side of 3.1.1 Check the tightness of
pump. the connections. Check
the hose for possible
damage.
3.2 Perforated diaphragm. 3.2.1 Replace the diaphragm.
3.3 Motor malfunctioning. 3.3.1 Replace the pump.
3.4 Debris under/in the valves. 3.4.1 Open the pump body by
unscrewing the two screws
and clean the valves. Clean
the outlet valves. (Viking
