System Description

WATER CIRCULATION SYSTEM
A system that consists of a hydraulic butterfly valve
assembly and a perforated 4” pipe located inside the
water tank. The system diverts the flow of water from
the spray system to the perforated pipe, circulating
the water in the tank. The circulation valve must be
closed to operate the spray system, and water
cannon.
SUCTION LOADING (IF EQUIPPED)
A second water pump mounted typically to the water
pump sump at the rear of the MTT. The suction
loading station is equipped with a manual diversion
valve that will switch the hydraulic oil flow from the
main discharge pump drive motor to the suction
loading pump drive motor. When oil is diverted to
the suction loading drive motor it can pull water from
a holding pond and fill the MTT. The suction loading
option includes lengths of 4” suction hose equipped
with quick couplers and a check valve inlet foot with
a debris screen. The suction hoses are typically stored
in tubes either built into the MTT or a hanging tube
arrangement.
