SAFETY
The pump is intended for non-corrosive and
•
petroleum based liquids. 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.
DIMENSIONS
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 fluid outlet. The fluid 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 fluid 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 that
1.
filter regulator to be installed prior to the air
inlet of the pump.
Remove the protective packaging from the
2.
pump and also the protective plugs.
Fit the 2” pump adaptor firmly on to the
3.
barrel.
Mount the pump into the pump adaptor and
4.
lock into position.
Fit and secure the outlet hose.
5.
Fit and secure the air inlet hose, slowly
6.
increase the air pressure letting the pump
slowly build up fluid pressure.
Ensure there are no leaks either on the air
7.
inlet or at the fluid outlet. To obtain maximum
vacuum all connections should be sealed and
tight.
Slowly increase the air pressure to optimum
8.
working pressure.
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 fluid outlet
must be depressurized completely. Follow pressure
relief procedure.
