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: The pumps from this model are not intended to pump fammable or combustible
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
Materials
CAUTION: Operating temperature limitations are as follows:
Operating Temperature
Max. Min.
Conductive Acetal: Tough, impact resistant, ductile. Good abrasion resistance and low friction
surface. Generally inert, with good chemical resistance except for strong acids and oxidizing
agents.
88°C -29°C
EPDM: Shows very good water and chemical resistance. Has poor resistance to oils and
solvents, but is fair in ketones and alcohols. 138°C -40°C
FKM:
aliphatic, aromatic and halogenated hydrocarbons, acids, animal and vegetable oils. Hot water
177°C -40°C
Hytrel: Good on acids, bases, amines and glycols at room temperatures only. 104°C -29°C
Neoprene:
chemicals, fats, greases and many oils and solvents. Generally attacked by strong oxidizing
acids, ketones, esters and nitro hydrocarbons and chlorinated aromatic hydrocarbons.
93°C -23°C
Nitrile:
resistance. Should not be used with highly polar solvents like acetone and MEK, ozone,
chlorinated hydrocarbons and nitro hydrocarbons.
88°C -23°C
Nylon: 6/6 High strength and toughness over a wide temperature range. Moderate to good
resistance to fuels, oils and chemicals. 82°C 0°C
Polypropylene:
acids and alkali. Attacked by chlorine, fuming nitric acid and other strong oxidizing agents. 82°C 0°C
PVDF:
Excellent for UV applications. High tensile strength and impact resistance. 121°C -18°C
Santoprene:
life. Excellent abrasion resistance. 135°C -40°C
UHMW PE: A thermoplastic that is highly resistant to a broad range of chemicals. Exhibits
outstanding abrasion and impact resistance, along with environmental stress-cracking
resistance.
82°C -37°C
Urethane: Shows good resistance to abrasives. Has poor resistance to most solvents and oils. 66°C 0°C
Virgin PTFE:
104°C -37°C
Maximum and Minimum Temperatures are the limits for which these materials can be operated. Temperatures coupled
with pressure aect the longevity of diaphragm pump components. Maximum life should not be expected at the extreme
limits of the temperature ranges.
Alloy C:
Stainless Steel:
nickel and nickel based alloy castings for general applications. Commonly referred to as 316 Stainless Steel in the pump industry.
Ambient temperature range: -20°C to +40°C
Process temperature range: -20°C to +80°C for models rated as category 1 equipment
-20°C to +100°C for models rated as category 2 equipment
In addition, the ambient temperature range and the process temperature range do not exceed the operating temperature range of
the applied non-metallic parts as listed in the manuals of the pumps.

AIR SUPPLY:
achieve desired performance. A pressure regulating valve should be installed to insure air supply
pressure does not exceed recommended limits.
AIR VALVE LUBRICATION:The air distribution system is designed to operate WITHOUT lubrication.
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.
