INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
SUMMIT PUMP MODEL CCFM GENERAL PURPOSE 11
6.7 PIPING CONNECTION – SUCTION / DISCHARGE
Lock out driver power before beginning to
work on pump.
Connect piping in a manner that is as short and direct as possible. Independent pipe supports, and
anchors must be used in all installations. Never support piping using the pump. When threaded
connections are used, an extendable pipe or flexible connection are possible options.
CAUTION
Never use force to align piping to the pump
threaded connections.
6.7.1 Suction Piping
The piping used should be as short as possible from suction source. Piping line size should be the
same diameter as the suction nozzle. Although, this may not always be the case, as high
viscosity, fluid velocity or system constraints may cause a change in size. All elbows 90° or 45°
should be a long-sweep. Any piping that causes air to become trapped should be avoided.
6.7.2 Discharge Piping
Generally, the diameter of the discharge piping should be the same diameter as the discharge
nozzle. In certain circumstances, this will not be the case, as the fluid being pumped will cause
the use of a different pipe size. In these circumstances, the use of a reducer/expansion fitting is
needed.
It is recommended to install an isolation discharge and suction valve to isolate the pump from the
system when down for maintenance.
