POWER-MASTER III DRUM PUMPS
Ball Type Foot Valve
Form 403663
ATTACHING AIRMOTOR TO
PUMPTUBE
1. Tightly attach tie rods to the airmotor
(use short threaded end of the tie rods).
2. Mount airmotor on top of the pump tube
outlet and tightly connect Coupling Nut
(Item 2) to airmotor piston rod.
3. Hand tighten tie rods to the pumptube
with four nuts supplied with airmotor.
4. Slowly cycle the pump several times,
using just enough air pressure to operate
the pump without stalling.
5. Stop the pump on an “up” stroke and
tighten the four nuts to securely fasten
the airmotor to the pumptube.
OPERATING PRECAUTIONS
Use Lincoln replacement parts to assure•
compatible pressure rating
HEED ALL WARNINGS•
Be sure material hoses and other•
components are able to withstand uid
pressures developed by this pump
Do not operate pump continuously at•
speeds in excess of 75 cycles per
minute.
Disconnect air line from pump air motor•
when system sits idle for long periods of
time.
SERVICING Before servicing or •
cleaning pump, or removing uid hose or
gun from a unit that has been used, be
sure to disconnect air lines and carefully
bleed pressure off of the system.
PREVENT STATIC SPARKING. If static
sparking occurs, re or explosion could
result. Pump, dispensing valve, and con-
tainers must be grounded when handling
ammable uids such as petroleum prod-
ucts, paints, lacquers, etc. and wherever
discharge of static electricity is hazard.
Check continuity (a good static wire•
connection) with an ohmmeter Place
one probe on one hose tting and the
other probe on other hose tting, conti-
nuity or proper grounding through hose
is good when a reading is obtained on
the ohmmeter
PREVENT FIRES. When pumping, •
ushing or recirculating volatile sol-
vents, the area must be adequately
ventilated.
Keep solvents away from heat, sparks •
and open ames. Keep containers
closed when not in use.
DO NOT allow pump to operate when
out of material.
PUMP PRIMING
To begin operation, the pump has to
be primed with the pumped material.
The Power-Master III pump is a double
acting (pumps material on ‘up’& “down”
stroke.) positive displacement recipro-
cating pump and as such intakes mate-
rial only on the “up” stroke.
To prime pump, open output line (material
valve) and slowly open air supply valve
until pump starts. Allow pump to cycle
very slowly until all air is pushed out of
lines and material lls up pump and lines.
Close output line (material shut-off valve)
- pump should stall against pressure
Note: Pumps are factory tested with light
oil and some of it is left in to protect pump
parts during storage and transportation.
To prevent contamination of material to be
pumped, ush pump before using.
