Introduction
The VETUS electric diaphragm pump has been designed for
use as a pump for contaminated fluids (with large particles)
such as waste, shower and bilge water.
The pump is self-priming. Therefore it is possible to install the
pump at a higher position than the holding tank or above the
bilge water level.
Running dry of the pump is allowed. However, unnecessary
running dry will shorten the service life of both the motor and
the diaphragm.
Always shut off all seacocks when leaving the ship.
WARNING
Obstructions in pressure and/or suction hose may be
harmfull to pump and/or electric motor.
By using a fuse with the recommended amperage (6 A
for 12 Volt and 4 A for 24 Volt) in the plus cable, the fuse
will blow if there are any blockages or when the outboard
shut-off valve is closed.
This will prevent damage to the pump or electric motor.
Flow direction
The desired flow direction rela-
tive to the foot determines how
the hose connections should be
made.
Be careful with the following
points:
- the direction in which the valves
are fitted.
- the 2 different screw-in cou-
plings, one with a large hole (at
A) and one with a small hole (at
B)
- the 2 different hose sockets,
one short (at A) and one long (at
B)
First fit the coupling in the hous-
ing.
Then fit the valve, the hose socket
and the coupling nut.
This method always makes sure
that the valve is fitted correctly.

Installation
Setting up
The space where the pump is installed must be dry and well
ventilated.
When selecting a place for the installation enough room for car-
rying out maintenance work must be kept in mind.
The pump can be mounted in all positions without impairing the
correct operation.
The pump is self-priming; the maximum suction height is
3-meter (10 ft). It is recommended to install the pump below
the minimum fluid level in the holding tank. Possible contami-
nants, remaining inside the pump during stand-still, will then be
flushed out easily during the next operation of the pump.
When increasing suction height and/or head the capacity of the
pump will decrease.
Keep the length of the tubes as short as possible; a Iarger
lenght of the tubing will diminish the capacity of the pump.
Every bend, valve and connection in the system will also dimin-
ish the capacity of the pump.
The maximum head is 5 meter (16 ft).
