OPERATION
THE REVERSIBLE VANE PUMP IS DESIGNED FOR INTERMITTENT
DUTY. DO NOT OPERATE PUMP FOR MORE THAN 30 MINUTES
CONTINUOUSLY.
Rotary Vane pumps must NOT be run dry, as the pumped liquid is
the lubricant for the rotor and vanes. Observe the outlet and shut
off pump as soon as liquid stops flowing. The pump cannot run
against a closed outlet.
Pressure for normal operation should not exceed 20 feet of head
(8.7 psi).
Excessive pressures will cause fuse to blow. Temperature of
pumped liquid may be in the range of 45°-165°F (10°-78°C).

MAINTENANCE
Check wires and connections to be sure corrosion is not adding
additional resistance to the motor circuit and causing a low
voltage condition at the motor. Low voltage can inhibit motor from
starting and cause fuse to blow.
Full voltage should be available to prevent motor damage. If
pump is to be used for water in freezing temperatures, drain by
loosening end cover screws.
DISASSEMBLY
1. Remove end cover screws, end cover and O-ring.
2. Withdraw rotor and vanes.
3. Loosen and remove the two slotted hex screws, which attach
body to motor.
4. Tap body lightly between ports and remove body from motor.
5. With a 1⁄ 2 " (12.7mm) diameter dowel, push against the shaft
seal from back (motor) side of the body to dislodge seal from
the seal bore.
NOTE: Do not tamper with or disassemble motor.
6. Remove slinger.

7. Replace slinger.
8. Lubricate seal with oil and position it in seal bore with lip, or
hollowed out side of seal, pointing towards the rotor/vane
bore.
With a 1⁄ 2 " (12.7mm) diameter dowel, push against the shaft
seal into its bore until it contacts the bottom.
9. Lubricate motor shaft and install body on motor.
10. Aligning flat in rotor with flat on motor shaft, install rotor.
Install vanes in vane slots of rotor.
11. Install O-ring and end cover. Tighten end cover screws.
EXPLOSION HAZARD: If pump is operated
in an area containing flammable vapors, wire leads
must be joined by insulated mechanical locking
connectors. Loose or inadequate wire connections
can spark resulting in an explosion. Property
damage, injury or death can occur.
