DESCRIPTION & SPECIFICATIONS:
The Series NPO embraces a line of 1", 1¼" and 1½" NPT
discharge, general liquid transfer and booster pump ap-
plication end suction centrifugal pumps. The liquid end
construction is of AISI 316 stainless steel, stamped and
welded. Open vane impellers are ideal for liquids with
suspended solids to ⁄ " diameter.

PIPING – GENERAL
Piping should be no smaller than the pump connection
size and kept as short as possible, avoiding unnecessary
fittings to minimize friction losses.
All piping MUST be independently supported and
MUST NOT place any piping loads on the pump.
NOTICE: DO NOT FORCE PIPING INTO PLACE
AT PUMP SUCTION AND DISCHARGE
CONNECTIONS.
All pipe joints MUST be airtight.
PiPinG – SUCTion
Short and direct suction piping is recommended. For
suction lifts over 10' (3 m) and liquid temperatures over
10º F (49º C), consult pump performance curve for net
positive suction head required (NPSH
If a pipe size larger than pump suction is required, an ec-
centric pipe reducer, with the straight side up, MUST be
installed at the pump suction.
If pump is installed below the liquid source, install a full
flow isolation valve in the suction for pump inspection
and maintenance.
NOTICE: DO NOT USE THE ISOLATION VALVE TO
THROTTLE PUMP . THIS MAY CAUSE LOSS
OF PRIME, EXCESSIVE TEMPERATURES
AND DAMAGE TO PUMP , VOIDING
WARRANTY.
If the pump is installed above the liquid source, the fol-
lowing MUST be provided:
To avoid air pockets, no part of the piping should be
above the pump suction connection.
Slope piping upward from liquid source.
Use a foot valve or check valve ONLY if necessary for
priming or to hold prime during intermittent duty.
The suction strainer or suction bell MUST be at least
3 times the suction pipe diameter area.
Insure that the size and minimum submergence over
suction inlet is sufficient to prevent air from entering
through a suction vortex.
PiPinG – DiSChArGE
Install a check valve suitable to handle the flow, liquids
and to prevent backflow. After the check valve, install an
appropriately sized gate valve to be used to regulate the
pump capacity, pump inspection and for maintenance.
When required, the pipe increaser should be installed
between the check valve and the pump discharge.
