I.O.M - 880RI SERIES
FLO FAB In Line pumps are designed to be mounted vertically in the pipe line with the motor
above the pump. Center line suction and discharge keep weight evenly balanced and directly
down upon the piping. No flexible connections to take up pipe misalignement are necessary
since pump is not permanently connected to anything but the piping and is free to move with
the expansion and contraction of the piping system. Support of the piping at the pump may be
made by two pipe hangers, floor saddles or floor flanges, placed on line close to the pump.
Selection of the actual type of support is determined after consideration of the structural cha -
racteristics at the location of the pump, size and weight of both the piping and the pump, ex -
pansion and contraction of the piping, etc. In other words, the same criteria and formula for
selecting piping supports are used with the additional consideration that the weight of the pump
is concentrated at one point in the piping. Otherwise, piping recommendations are the same as
for other types of pumps. For example, gate valves should be installed at both the pump suction
and discharge to permit servicing of the pump without draining the entire system. If vertical in-
line pumps are mounted in a straight horizontal run of piping, then the weight of the piping and
pump system is generally supported by pipe supports, or spring hangers, and experience has
shown that no addi tional pump support, vibration or noise isolation devices are required.
A. INSTALL VERTICAL IN INLINE PUMPS WITH MOTOR IN VERTICAL POSITION.
B. MAKE CERTAIN THE SPACE ABOVE THE PUMP IS SUFFICIENT TO GIVE CLEARANCE FOR
LIFTING THE PUMP ASSEMBIY FROM THE CASING. ALSO THE SPACE AROUND THE
PUMP SHOULD BE LARGE ENOUGH FOR GENERAL ACCESSIBILITY AND VENTILATION.
C. SUPPORT PUMP ONLY BY PIPING.
D. MANUALLY VENT ALL AIR FROM CASING.
E. MAKE SURE SUCTION VALVE IS WIDE OPEN BEFORE STARTING MOTOR
F. CHECK MOTOR ROTATION (CLOCKWISE LOOKING DOWN FROM TOP OF MOTOR).
