WT5C SERIES WATER TRAILER • OPERATION MANUAL — REV. #6 (05/28/21) — PAGE 13
GENERAL INFORMATION
APPLICATION
Typical applications for Multiquip’s Water Trailers include:
dust control, emergency fire fighting response, construction,
agricultural support and equipment wash down.
The WT5C Series are industrial 525-gallon Water Trailers.
Each water trailer comes with a centrifugal pump, flexible
suction/discharge manifold system with simple valve
controls, and a rugged polypropylene water tank.
Manifold System
1.5" CAM and groove QD
2.0" CAM and groove QD left and right sides (discharge)
2.0" CAM and groove QD water tank fill (suction)
3-position manifold control lever Off-Suction-Discharge
2-position spray bar control lever On-Off
Three 3/4" garden hose bibs
Water Tank
Water tank capacity is 525 gallons (1,987 liters). Tank is
made of durable 3/16" wall polypropylene with integrated
baffles to reduce water movement during transportation.
Water tank can be quickly filled via 2" diameter steel
pipe with 2" QD coupler or vented 12" diameter port. In
addition, water tank has a rear spray bar that operates
under pressurized or gravity feed settings.
Additional features also include two standard garden hose
valves (fill/discharge and tank drain).
Trailer and Frame
The trailer is a DOT-approved, double-axle trailer. Trailers
can be ordered with either a standard hydraulic surge brake
system or electric brake system. Trailers can be configured
with various hitch options.
For convenience, a formed steel hose bin has been
provided for the storage of hoses and accessories during
transport.
Pump
The Multiquip QP2HLF Centrifugal Pump, which is used
in conjunction with the water trailer, has the capability to
pump at a rate of approximately 158 gallons/minute (gpm)
or 600 liters/minute (lpm).
Centrifugal or self priming pumps are designed to purge
air from the suction line and create a partial vacuum in the
pump body.
The reduced atmospheric pressure inside the pump allows
water to flow through the suction line and into the pump
body. The centrifugal force created by the rotating impeller
pressurizes the water and expels it from the pump.
This centrifugal pump should only be used in clear water
applications (agricultural, industrial, residential) as it only
has a limited solid handling capability of only 10% by
volume.
Elevation
Higher elevations will effect the performance of the pump.
Due to less atmospheric pressure at higher altitudes,
pumps
DO NOT
have the priming ability that they have at
sea level. This is due to the “thinner air” or lack of oxygen
at higher altitudes.
Power Plant
The centrifugal pump, used by the water trailer, is powered
by a 3.5 horsepower, air- cooled, 4-stroke, single-cylinder,
HONDA GX120 gasoline engine that incorporates a low
“Oil Alert Feature.”
Oil Alert Feature
In the event of low oil or no oil, the HONDA GX120 engine
has a built-in oil shut-down feature. In the event the oil
level is low the engine will automatically shut down and
cannot be restarted until the oil level is brought up to a
safe operating level.
