Direct Drive – Clearance should be left between drive shaft
and pump shaft when installing coupling. Always mount and
align pump and drive shaft before tightening the coupling
set screw.
3. SPEEDS – 100 RPM to the maximum shown in the perfor-
mance table. Consult the factory for operation at speeds
above those shown. For longer pump life, operate at
lowest possible speeds.
4. SELF-PRIMING – Primes at low or high speeds. For
vertical lift of 10 feet (3.0mm), a minimum of 800 RPM
is required. Pump will produce suction lift of up to 22 feet
(6.7m) when wetted. BE SURE SUCTION LINES ARE
AIRTIGHT OR PUMP WILL NOT SELF-PRIME.
5. RUNNING DRY – Unit depends on liquid pumped for
lubrication. DO NOT RUN DRY for more than 30 seconds.
Lack of liquid will damage the impeller.
6. NOTICE – Do not pump light fraction petroleum derivatives,
solvents, thinners, highly concentrated or organic acids.
Damage to pump may result. Consult Jabsco Chemical
Resistance Table, available upon request from Jabsco,
for proper body materials and impeller compounds. If
corrosive fluids are handled, pump life will be prolonged if
pump is flushed with water after each use or after each
work day.

tractor tires.
PLUMBING AND HOME EMERGENCY USE: Pumping out
flooded basements, Cesspools, Sumps, Water heaters and
water closets, Drains and sinks, Draining fishponds and
pools.
1. INSTALLATION – Pump may be mounted in any
position. Intake and discharge ports are determined by
the direction of shaft rotation (refer to Dimensional
Drawing). Before installing, turn the pump shaft in the
direction of the operating rotation.
2. DRIVE – Belt or Direct with flexible coupling.
NOTICE: Do not press pulley or coupling on the
shaft without supporting the shaft at the opposite
end to prevent its movement into the impeller bore.
Belt Drive – Overtight belt load will reduce pump
bearing life.
