Installation & Maintenance Instructions
Installation
1. Remove the drum pump and motor from its packaging and inspect for shipping damage.
2. Turn the pump coupling to verify there is no binding.
3. Adjust the coupling so that the empty slots in the insert are at 3 and 9 o’clock with the pump discharge at 12
o’clock.
4. Install the motor according to instructions in the appropriate motor manual.
5. Attach discharge hose and install pump into the container. Torque Finish Thompson hose clamps to 25 in-lbs
(2.8 N·m).
Note:
Pumps with the standard 1” barb spout ship with a variable orifice fitting, which limits the flow of the
pump to 10 gpm. As it is cut away, flow will increase minimum up to maximum flow (to increase flow, simply
trim back orifice) See Fig. 1.
Operation
1. Make sure the motor (electric or air) is properly installed on the pump tube and is in the off position. See
motor instruction manual for installation instructions.
2. Insert the pump tube into the fluid to be dispensed and the hose into the container to be filled prior to
starting the pump. Bung adapters are available to provide a tighter fit between the pump tube and bung
opening of a standard drum. Check drum pump accessories at www.finishthompson.com or contact your
local Finish Thompson distributor for bung adapter info.
3. Make sure the pump’s discharge hose is properly secured before operating the motor.
4. Begin pumping by turning the motor on and verifying that there are no leaks. If leaks are noticed immedi-
ately turn the motor off and check all discharge hose connections.
NEVER
allow the pump to run dry.
Maintenance
Disassembly
1. Carefully place the pump head (item 5) in a vice (do not crush), and unthread the intake tube (item 6) by
turning it clockwise (left hand thread). Pull the intake tube (item 6) carefully off the bottom of the pump
shaft.
