READ ME FIRST - IMPORTANT INFORMATION

CHEMICAL REACTION DISCLAIMER

The user must exercise primary responsibility in selecting the product’s materials of 

construction, which are compatible with the fluid(s) that come(s) in contact with the product.   

The user may consult manufacturer and a manufacturer’s representative/distributor agent to  

seek a recommendation of the product’s material of construction that offers the optimum available 

chemical compatibility.
However neither manufacturer nor a gent shall be liable for product damage or failure, injuries, 

or any other damage or loss arising out of a reac-tion, interaction or any chemical effect that 

occurs between the materials of the product’s construction and fluids that come into contact 

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 flammable or combustible 

materials (consult factory).

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 

event of a diaphragm rupture material can be forced out of the air exhaust muffler. If product is 

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. 

If pump is used with materials that tend to solidify or settle pump should be flushed after 

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 

fasteners to loosen. Re-torque all fasteners to insure against fluid or air leakage. 

6.  Unpack the pump and examine for any signs of shipping damage.   If damage is detected, 

save the packaging and notify the carrier immediately.
