INSTRUCTIONS for
CUT WATER PUMP
Part Numbers 36942 (Hi-Flow) and 33262 (1/2 GPM)
INTRODUCTION

August, 2004
The Cut Water Pump is intended to supply cut water
to the PT-15XL water injection torch. It may be used
in other applications where water requirements do
not exceed the pump capacity of 0.5 gpm @ 200
psig maximum delivery.
This manual also covers the Hi-Flow Pump
Assembly used on the 1000 AMP water injection
system.
DESCRIPTION
The pump assembly consists of a base plate on
which are mounted the motor and relay. The pump
is mounted to the motor with a carbonator clamp.
The relay Is prewired with a 25-ft. power cable with
a 115 VAC plug. A 25-ft. control cable and plug
assembly with an amphenol plug is provided for
connection to the Smart Flow 2.5 (and higher) Flow
Control. These pump assemblies are also used for
replacement and retro fitting to earlier version flow
controls such as the ESP Flow Control.
A positive displacement rotary vane pump is
mounted to the motor. The 1/2 Hp, 115/230
VAC, 50/60 Hz motor is drip-proof and thermally
protected. The motor is supplied wired for 115 VAC.

0.75 gpm @ 250 psi max. delivery pressure
Note: Water Injection systems that use this pump require a minimum of 0.50 gpm
at the flow control. 0.75 gpm at the pump provides a safety margin.
2.26 gpm @ 250 psi max. delivery pressure
Do NOT operate with delivery pressure set
to more than 220 psig. Do NOT operate for
more than 2 minutes with no flow (with
the pump dead-ended). Do NOT operate
for extended periods of time with less
then 0.2 gpm flow.
Adjusting Delivery Pressure
Pump Identification
Procedure
Remove acorn nut on pump.
1.
2.
Turn screw in to increase pressure.
3.
Turn screw out to reduce pressure.
Replace acorn nut.
4.
The pump type can be easily identified by the
physical size. Hi-flow pump is bigger than the
standard cut water pump. See dimensions at left.
