SAFETY
The pump should be operated in con-
junction with the requirements of the
Health and Safety at Work Act, 1974.
Your Warren Rupp Pump E02/X02
Model is a high performance unit
capable of achieving high outputs at high
efficiencies. However, as is common
with pneumatic equipment, the pump
efficiencies is reliant upon the air being
clean, dry and filtered. Failure to comply
with these requirements may lead to
loss of performance and reduced
component life and in extreme cases,
permanent damage to the pump.
To avoid leaks, ensure that all fluid con-
nections are tight. The use of PTFE
thread tape correctly applied should
ensure 100% leakproof connections.
Failure to ensure 100% sealability
of the suction connection could ad-
versely affect suction performance.
If you are pumping hazardous fluids,
or operating the pump in an enclosed
area, it is essential that the exhaust
from the pump is piped away to a safe
location. When pumping hazardous
fluids the above instructions must be
adhered to in order to ensure safe
operating procedures. (Under certain
operating conditions the failure of
internal components can lead to the
pumped fluid being exhausted via the
pump exhaust outlet). See Fig. 2.
WARNING
NEVER place your hands over or near the pump suction port.
Powerful suction could cause serious bodily injury.

FLUSH THE PUMP
This pump was tested with water con-
taining an oil-based rust inhibitor. If
this solution could contaminate or
react with the fluid you are pumping,
flush the pump thoroughly with a
solvent/detergent to clean internal
components. The solvent/detergent
must be compatible with the pump
materials of construction. Care should
be taken to flush the pump each time
it is disassembled for maintenance or
repair.
CAUTION
Ensure that only the recommended grade
of lubricating oil is used. Warren Rupp
E02/X02 Model Pumps require a SAE 10
lubricating oil. Other grades of oil may
cause the Air Logic System to operate
intermittently, thereby causing a loss
of output and failure to operate.
If the pump accelerates or is running
too fast due to a lack of fluid, then
stop it immediately by shutting off the
air supply. A dry pump will accelerate
to a high speed causing wear to
elastomers.
If the fluid you are pumping tends to dry
up or set when it is not moving, then
flush the pump as often as necessary to
prevent the fluid from drying in the pump.
Drain the pump thoroughly before storing.
If feasible, invert pump to allow any fluid
to drain from the non-return valves.
