Brine, etc.
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
Dimensional Drawing). Before installing, turn the
pump shaft in the direction of the operating rotation.
2. DRIVE – Belt or Direct with flexible coupling. If pulley
or coupling is a press fit on shaft, remove end cover
and impeller and support shaft at impeller end while
pressing drive on shaft.
Belt Drive – Overtight belt load will reduce pump
bearing life.
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
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 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.
7. PRESSURES – Consult Head Capacity Table for
recommended maximum for continuous operation. If
pressures exceed those shown, consult the factory.
8. TEMPERATURES
• Neoprene: 45° to 180°F (7° to 82°C)
• Nitrile: 50° to 180°F (10° to 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 impeller:
Atlas “Perma-guard”, Du Pont “Zerex” and “Telar”,
Dow Chemical “Dow-guard” and Olin Mathison “Pyro
Permanent”.
NOTICE – To avoid pump damage, do not use
petroleum based anti-freeze compounds or rust
inhibitors.
10. SPARE PARTS – To avoid costly shutdowns, keep a
JABSCO Service Kit on hand.
Injury hazard. Exposed pulleys and belts can
cause injury. Install shield around pulleys and
belts. Stay clear while machinery is operating.
