JOCKEY
PUMP
NPR280
System Static Pressure Supply Device For Foam Systems
Compatible With Foam Concentrates
Compact Design
2 GPM @ 200 PSI
Positive Displacement
Description
The Foam Concentrate Jockey pump
is used in In-Line Balanced Pressure
(ILBP) Proportioning Systems to maintain pressure on the foam concentrate
discharge line that supply remotely
mounted ILBP modules. The pump
is designed to maintain the foam
concentrate pressure within preset
limits and at the same time maintain
foam concentrate volume in the supply
piping. The jockey pump provides
compliance with NFPA to insure the
integrity of the foam concentrate
piping with regard to piping installed
underground or piping above ground
exceeding 50 feet.
Features
• Compact design provides a small
foot print
Applications
• In-Line Balanced Pressure (ILBP)
Proportioning Systems
• Any application requiring long foam
concentrate lines between the main
foam concentrate pump and the
proportioning device
Specifications
Jockey pump shall be a positive
displacement, spur gear type, foam
concentrate pump with capacity for
2 GPM (foam concentrate) @ 200 PSI.
Head, casing & separation plates shall
be fabricated from cast iron or equal
with precision ground heat treated spur
gears and case hardened steel shafts
with Viton lip seals. Viton O-rings shall
be provided between all pump sections
to insure positive sealing. The suction
and return connections shall be ½”
FNPT. Pump shall be supplied complete
with either a ODP or TEFC motor, direct
coupled with a “C” flange bracket
and flexible coupling. Motor shall be
1 HP, 3/60/208-230-460V, 1725 RPM,
143TC frame, rated at 40° C. ambient
with a 1.15 service factor. A separate,
½" X ¾" cast bronze relief valve shall
be supplied with pump. It shall have
lapped seats for optimum performance,
and ball bearing pivot between disc &
spring to correct for misalignment and
compensate for spring side thrust.
Valve shall be specifically designed for
use in liquid service and shall be set
to relieve at 225 PSI. Pump motor shall
be sized with sufficient horsepower to
allow operation with relief valve full
open without overloading the motor.
