READ ME FIRST - IMPORTANT INFORMATION
CHEMICAL REACTION DISCLAIMER
The user must exercise primary responsibility in selecting the product’s materials of
The user may consult manufacturer and a manufacturer’s representative/distributor agent to
chemical compatibility.
However neither manufacturer nor a gent shall be liable for product damage or failure, injuries,
with the product’s components.
SAFETY PRECAUTIONS
READ THIS MANUAL COMPLETELY BEFORE INSTALLING AND OPERATING THIS PUMP.
FAILURE TO FOLLOW THESE PRE-CAUTIONS CAN RESULT IN SERIOUS INJURY OR
DEATH.
WARNING:
WARNING: Do not exceed maximum pressure stated on the pump serial number sticker. Pump
exhaust may be loud and contain particles. Wear appropriate ear and eye protection. In the
hazardous or toxic pipe exhaust to appropriate safe area.
WARNING: Chemical Hazard. This pump is used for transferring many types of potentially
dangerous chemicals. Always wear protective clothing, eye protection and follow standard safety
procedures when handling corrosive or personally harmful materials. Proper procedures should
be followed for draining and decontaminating the pump before disassembly and inspection of
the pump. There may be small quantities of chemicals present during inspection.
WARNING: Before maintenance or repair, close the compressed air supply valve, bleed the
pressure and disconnect air line from the pump. Discharge line may be pressurized. Any
pressure must be relieved before service.
CAUTION
1. To help avoid unnecessary damage to the pump, do not allow pump to run dry for long
periods of time.
2. Use only genuine Pump-Fit replacement parts to assure compatible pressure rating and
longest service life.
3.
each use to prevent damage.
4. nstall the pump in a vertical position or the pump may not prime properly.
5. Re-torque all fasteners before operation. Creep of housing and gasket materials may cause
6. Unpack the pump and examine for any signs of shipping damage. If damage is detected,
save the packaging and notify the carrier immediately.

MATERIAL PROFILE
Diaphragm Material
CAUTION: Operating temperature limitations are as follows:
Operating Temperature
Max. Min.
Viton:
177°C -40°C
PTFE (Teon):
176°C 4°C
Santoprene: Good abrasion resistance, chemical resistance and heat resistance, suitable for
general acid and alkali, not suitable solvent. Can replace the EPDM/EPR material. 104°C -29°C
Hytrel:
materials. 104°C -29°C
EPDM: Abrasion resistance, aging resistance, ozone resistance , suitable for general acid and
alkali. 122°C -40°C
Buna-N: Widely used in gasoline and other oil products. Suitable for use at room temperature. 100°C -40°C
GE: Better abrasion resistance than Hytrel, the same chemical resistance as Buna-N. 104°C -29°C
Note: The maximum and minimum temperature is the limited operating temperature of these materials. Temperature and
pressure will aect the diaphragm life. Operating within suggested maximum and minimum temperature will maximise
the lifespan of the pump.
Pump Body Material
CAUTION: Operating temperature limitations are as follows:
Operating Temperature
Max. Min.
PP: Medium abrasion resistance, good chemical resistance, good versatility, especially for
common acid-base. 80°C -4°C
POM: Good solvent resistance, abrasion resistance. Low friction, low moisture absorption. 176°C 4°C

pressure does not exceed recommended limits.
AIR VALVE LUBRICATION:The air distribution system is designed to operate WITHOUTlubrication.
This is the standard mode of operation. If lubrication is desired, install an air line lubricator set to
consumes. Consult the Performance Curve to determine air consumption.
AIR LINE MOISTURE:Water in the compressed air supply may cause icing or freezing of the
exhaust air, causing the pump to cycle erratically or stop operating. Water in the air supply can be
reduced by using a point-of-use air dryer.
