TwinForce™ Series Waterblast Unit

Hydro-Throttle Switch (Optional)

The hydro-throttle switch senses the pressure

within the pump and allows the engine to idle

when the operator is not blasting.
Refer to

“Using the Hydro-Throttle (Dump Sys

tem Only)” on page 31

Rupture Discs

Two rupture discs are used in the system. The

rupture discs provide protection from excess

pressure in the system. If system pressure

were to exceed the rated pressure of the discs,

the discs would burst. If a disc bursts, water

will flow through the ruptured disc to provide

relief for the system and protect components

from excess pressure. Check the discs before

operating the pump. Keep a supply of rupture

discs on hand for use. If a rupture disc should

burst, there is no way to build pressure until

the disc is replaced. Use only genuine Jet-

stream rupture discs properly rated for the

intended operating pressure.

Bypass Valve

The bypass valve controls the pump pressure

by bleeding off excess water and diffusing it to

low pressure. Turning the knob allows the op-

erator to adjust pressure during operation and

relieve pressure when not waterblasting.
The bypass valve controls pressure by allowing

water to bypass though the valve. A discharge

hose is attached to the bypass valve. The hose

extends to the other side of the unit where it is

attached to a drain elbow. Water that bypasses

the valve will drain from the bypass drain

throughout operation.
The proper use of the bypass valve is to install

the correct size nozzle in the system so that

the bypass valve can be closed during opera-

tion. A combination of plunger size, engine

rpm, and nozzle will allow the bypass valve to

close at almost all flow rates.

Note:

For units employing a shut in sys-

tem, a regulator valve is substi-

tuted for a bypass valve.

Regulator Valve (Not Shown)

For shut-in systems (where no low pressure

water dumps from the gun), the bypass valve

is replaced with a regulator valve. The regu-

lator maintains constant system pressure
