SAFETY
The pump is intended for use with anti-freeze•
and anti-freeze/water solution. It may NOT
be used for other purposes or for pumping
gasoline, or other explosive liquids.
Check that all components used are suitable•
for the operating pressure of the system.
Do not use higher pressure than required for•
the satisfactory functioning of the system.
Before work is undertaken on the pump the•
compressed air should be disconnected from
the pump and the whole system should then
be depressurized.
Check all components thoroughly for damage•
and leakage.
Ensure that the compressed air is disconnected•
from the pump and the system is depressurized
when system is not in use (i.e. overnight or
during longer shut down periods) as there is
always a risk of hoses bursting or pipework
leaking etc.
GENERAL
The pump is made up of two main parts: A
compressed air operated two way piston air motor
and a double acting liquid pump. The liquid is
sucked into the pump tube via the bottom valve.
When the piston moves upwards liquid is forced
out of the uid outlet. The uid is forced out of the
pump when the piston is moving in both directions.
The relationship between the air piston and the
pump piston determines the ratio of the pump. If
the pump ratio is 3:1 the theoretical uid pressure
will be 3 times to the air pressure, when the pump
stalls out. The air is exhausted from the pump via
a sound attenuator.
INSTALLATION / OPERATION
To achieve long pump life we recommend that1.
lter regulator to be installed prior to the air
inlet of the pump.
Remove the protective packaging from the2.
pump and also the protective plugs.
Fit the 2” pump adaptor rmly on to the 3.
barrel.
Mount the pump into the pump adaptor and4.
lock into position.
Fit and secure the outlet hose.5.
Fit and secure the air inlet hose, slowly6.
increase the air pressure letting the pump
slowly build up uid pressure.
Ensure there are no leaks either on the air7.
inlet or at the uid outlet. To obtain maximum
vacuum all connections should be sealed and
tight.
Slowly increase the air pressure to optimum8.
working pressure.
MAINTENANCE
Before any service work is carried out the1.
compressed air must be turned off to the pump
or the air coupling disconnected. The uid
outlet must be depressurized completely.
Clean the air lter, remove all pollutants 2.
including condensed water.
Check system for any air or uid leaks.3.
Always keep the equipment clean and remove4.
foreign objects, ensure no pollutants enter
the barrel as these will be pumped into the
system.
When changing the barrel make sure the pump5.
remains clean (Do not put on to oor otherwise
the oil will become polluted).
When depressurizing the system or removing6.
the outlet hose from the pump ensure there
is a container available to drain the excess
uid into.
The maximum permitted air pressure is 150 psi, do not
exceed this limit. Service: Before any servicework is
carried out the compressed air must be turned off to the
pump or the air coupling disconnected. The uid outlet
must be depressurized completely. Follow pressure
relief procedure.
