INTRODUCTION
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 maxi-
mum delivery.
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
and with a 25-ft. control cable and plug assembly with
an amphenol plug for connection to the ESP Plasma
System 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.

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: Remove acorn nut on
