INSTALLATION, OPERATION,
LUBRICATION, MAINTENANCE AND
STORAGE INSTRUCTIONS
SAFETY
Electrical power or engine must be shut off completely
before attempting service on the pump or its drive. Air
surrounding the unit to be free of toxic, flammable, or
explosive gases.
Tools needed should be planned for in advance (see
valve seat pulling instructions), and should be clean
and of adequate size. A torque-wrench will be required
to tighten connecting rod cap screws.
A properly sized and set relief valve installed in the
pump discharge system (ahead of any block valves) is
necessary to protect personnel and to avoid dangerous
overpressure. The relief valve set pressure should
be not more than 25% above the design operating
pressure and should discharge to tank or to the
atmosphere (toward the ground), and must not be
directed back to the pump suction system.
WARNING: Improper use of this equipment could result
in loss of life.
CALIFORNIA PROPOSITION 65 WARNING:
WARNING: This product and related accessories
contain chemicals known to the State of California to
cause cancer, birth defects or other reproductive harm.
STORAGE
Pumps are shipped dry from the factory. If a pump has
been in storage in a humid environment for more than
6 months the crankcase cover should be removed and
carefully examined for rust or water collected in the
power end. Flush out any evidence of rust or damage
that exists, using a light clean oil.
Pumps to be placed in extended storage should be
cleaned, repaired as needed, and completely filled to
the top with clean oil to prevent rusting. Rotate pump
monthly 4-1/2 revolutions. Plug all openings to prevent
air entry and oil leakage.
Fluid ends must be completely drained of water and
suction and discharge ports blanked off. Store pump in
a clean, dry location.
PUMP LOCATION AND PIPING DESIGN
Locate pump and driver in a clean, well drained,
ventilated, and brightly illuminated area, with adequate
working spaces around the pump to provide ample
access to fluid end, power end, and associated drive
elements. Do not expect good maintenance to result if
the pump is positioned on muddy terrain, or in a dirty,
cramped, dimly lighted area!
The supply tank(s) should be large to allow dissolved
air and other gases to escape from the liquid and allow
suspended solids to settle out before entering pump.
A system employing dams and settling chambers
is desirable.
CAUTION: All pumps should be installed level. For
mobile applications the maximum angle of intermittent
operation pumps (SC pumps) should be no more than
5 degrees in any one direction.
Pumps are not designed to withstand piping weight,
vibration, and the effects of thermal piping expansion/
contraction. Piping loads may be considerable and the
weight of all valving, dampeners, filters, and associated
forces, moments, and couples must be completely
isolated. Use flexible hoses and rigid piping supports to
isolate the pump and its driver from these effects.
SUCTION PIPING
No part of the piping system deserves more careful
planning than the suction piping system. Suction
piping must be SHORT, DIRECT, and OVERSIZE. Use
one pipe size larger than the pump suction connection.
The shorter it is, the better! 1 to 3 feet per second
suction velocity is acceptable.
Reference the following table to size a direct suction
line from a tank to a pump.

3" – 4"
MA-60H
MA-60M
SC-95
RO-86
Use no elbows, tees, or restricted port valves in
this line. Do not install orifice plates or positive
displacement type fluid meters in the suction line
which act as flow restrictors. Avoid the use of suction
filters, if possible. Consider filtering the liquid as
it enters the supply tank rather than as it leaves
it. The use of an eccentric reducer with the flat
side up located at the pump suction connection is
recommended. The suction line should slightly rise
from tank to pump, and loops in which air may collect
must be avoided.
The absolute pressure in a suction line may be less
than atmospheric pressure and air may be "sucked"
into the line unless all flanges and connections are
airtight and watertight. If you can see water leaking out
of a suction line when the pump is still, that may mean
air is being sucked in when the pump is running.
