General Safety Information
The Wesco Stainless Steel Rotary Pumps are designed for specific functions. To insure proper use, the following instructions
must be adhered to:
(1) Always carefully read, thoroughly understand and follow the pump operating instructions. Use this pump correctly and
with care for the purpose for which it is intended. Failure to do so may cause damage or personal injury and will invalidate
the warranty. Retain instructions for future reference.
(2) Contact your chemical or fluid supplier to check for compatibility with pump prior to installation and operation.
(3) Prior to use, always carefully and thoroughly read and understand the OSHA information contained in the Safety Data
Sheet supplied for the chemical which is to be pumped.
(4) Wear protective clothing (goggles, face masks, long sleeves, long pants, gloves, aprons, etc.) as set forth in the OSHA
Safety Data Sheet when pumping hazardous chemicals.
(5) When using flammable liquids, pump containers should be grounded to avoid static electricity.
(6) Any pump used for transferring flammable liquids must be stored in a ventilated area after use.
(7) Pump should be washed out before it is used since processing lubricants may contaminate the fluids.
(8) Prior to use, inspect your pump thoroughly verifying its proper assembly.
(9) If pump is removed from drum, it should be thoroughly rinsed in a liquid that is compatible with both the pump and fluid.

Assembly and Installation
(1) Check to see if all parts are included.
(2) Screw and discharge spout (Item 20) into pump body (Item 1) outlet using PTFE sealant tape provided. Do not use pipe
sealant.
(3) Screw handle assemble to crank arm (Item 12) using hex nut (Item 15) supplied. Keep handle shaft from turning. Tighten
hex nut against crank arm. Then insert crank arm assembly onto pump shaft, taking care to align set screw (Item 16) to
indent in rotor (Item 2).
(4) In order to avoid leakage, please use PTFE tape provided to seal three suction tubes (Item 19). Insert bung adapter
(Items 17) into section tube (Item 19) and thread suction tube into pump inlet.
(5) Insert pump and suction tube assembled with bung adapter into the drum, and then tighten bung adapter thumb screw
(Item 18) by hand. Be sure to set pump and suction tube assembly so that suction tube is at the desired depth in the
drum and is not blocked.
Operation
(1) To begin pumping fluid, rotate handle clockwise several times making complete revolutions until fluid begins to flow.
Several revolutions will be made with no fluid dispensed as pump needs to prime, once primed, fluid flow begins as
handle is rotated.
(2) For siphoning or draining fluid back into drum, place handle in the straight down position.
(3) To stop siphoning and maintain suction or prime, leave handle in horizontal position.
(4) If corrosion builds up in pump due to lack of use or fluid being pumped, adding penetrating oil into the pump inlet may
help free pump. Remove pump from application, add penetrating oil, let soak, and then crank several times.
(5) Regularly check pump and suction tubes for leaks. Leaks in the suction line or in pump housing will cause inefficient
pumping and loss of prime.
