APPLICATIONS
MARINE: Pumping bilges, washdowns, circulating water
in bait tanks, utility dockside pump, engine cooling.
INDUSTRIAL: Circulating and transferring, velocity-mix-
ing, pumping machine tool coolants, return spill, sump
drainage, chemicals, pharmaceuticals, soap, liquors,
ink, dyes, alcohol, various acids, tanning liquors, glycer-
ine, brine, etc.
FARMING: Pumping water for stock, pumping water
from shallow wells and cisterns, pumping liquid ballast
into tractor tires.
PLUMBING & HOME EMERGENCY USE: Pumping out
flooded basements, cesspools, sumps, water heaters
and water closets, drains and sinks, draining fishponds
and pools.
OPERATING INSTRUCTIONS
1. INSTALLATION – Pump may be mounted in any
position. Intake and discharge ports are determined
by the direction of shaft rotation (refer to Dimen-
sional Drawing). Before installing, turn the pump
shaft in the direction of the operating rotation.
2. DRIVE – Belt or Direct with flexible coupling.
Belt Drive: Overtight belt load will reduce pump
bearing life. Direct Drive is recommended for oper-
ating speeds above 1750 RPM.
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.
NOTICE: If the drive pulley or coupling must be pressed
on the shaft, remove the end cover and impeller and
support the shaft from the impeller end during the press
operation. Do not hammer a pulley or coupling on the
shaft. Failure to follow the above instructions can dam-
age the pump.
3. SPEEDS – 100 RPM to the maximum shown in the
performance 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 dry suction lift of 10 feet, a minimum of 800
RPM is required. Pump will produce suction lift up to
22 feet when wetted. BE SURE SUCTION LINES
AREAIRTIGHT OR PUMP WILL NOT SELF-PRIME.
Other JABSCO models are also available in bronze,
plastic and stainless steel. JABSCO Pureflo®pumps
are also available for sanitary applications.

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 – If pumping light fraction petroleum deriv-
atives, solvents, thinners, highly concentrated or
organic acids, consult Jabsco Chemical Resistance
Table (which is available upon request from ITT
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.
7. PRESSURES – Consult Head Capacity Table for
recommended maximum for continuous operation. If
pressures exceed those shown, consult the factory.
8. TEMPERATURE – Neoprene 45°–180°F (7°–82°C)
Nitrile 50°–180°F (10°–82°C).
9. FREEZING WEATHER – Drain unit by loosening
end cover. The following anti-freeze compounds can
be used without any adverse effects to the neoprene
impeller: Atlas “Permaguard”, DuPont “Zerex” and
“Telar”, Dow Chemical “Dowguard” and Olin
Mathison “Pyro Permanent”. Most Methyl alcohol
(methanol) based antifreeze can be used.
DO NOT USE PETROLEUM BASEDANTI-FREEZE
COMPOUNDS OR RUST INHIBITORS.
10. GASKET – Use a standard pump part. A thicker
gasket will reduce priming ability. A thinner gasket
will cause the impeller to bind. Std. gasket 0.010"
thick.
11. GREASE CUPS – Fill grease cups with water pump
grease. Grease cup cap should be firmly tightened
about every 50 hours of pump service while pump is
operating. Leakage may occur through grease cups
at pressures above 20 p.s.i. If this occurs, replace
grease cups with ball check grease cups.
12. SPARE PARTS – To avoid costly shut downs, keep
a Jabsco Service Kit on hand.
SERVICE INSTRUCTIONS
DISASSEMBLY
1. Remove end cover screws, end cover and gasket.
2. Remove drive coupling or pulley and loosen packing
nut.
3. Remove shaft and impeller assembly from body.
4. Slide impeller off shaft towards pump drive end.
5. Remove cam screw and cam, clean off Permatex.
6. Remove packing nut and gland.
7. Remove packing with pick or screwdriver.
8. Remove grease cup caps and clean grease cups.
Use a small wire to ensure grease passage is open
to shaft bore.
9. Inspect all parts for wear or damage and replace if
necessary.
ASSEMBLY
1. Dip new packing in SAE 10 or 20 weight oil and
install packing, packing gland and packing nut.
2. Apply sealant to cam screw threads and top and
back end of cam and install in body with cam screw.
3. Install impeller key in shaft (dress if necessary) and
slide the impeller on the shaft from the pump drive
end.
Impeller can be installed in only one direction;
pinned end of keyway toward drive end of pump.
4. Install shaft and impeller assembly in body. (Dip
shaft in SAE 10 or 20 weight oil and lube impeller
bore with water pump grease prior to assembly.)
5. Install gasket and end cover with end cover screws.
6. Fill grease cups full and grease cup caps 3/4 full with
water pump grease. Install grease cup caps and
tighten firmly.
7. Hand tighten packing nut. During operation, tighten
packing nut until pump stops dripping; set locking
nut. NOTE: Packing and shaft life will be improved if
pump is allowed to drip about 3 drops per minute.
After a few minutes of operation, re-tighten grease
cup caps.
