WT5HP/WTE5HP/WT5HPSG WATER TRAILERS • OPERATION MANUAL — REV. #1 (03/14/17) — PAGE 13
GENERAL INFORMATION
APPLICATION
Typical applications for the Multiquip's High Pressure
Water Trailers include: dust control, emergency fire fighting
response, construction, agricultural-irrigation support, and
high jetting equipment wash down.
The WT5HP/WTE5HP are industrial 525-gallon Water
Trailers. Each water trailer comes with a high pressure
centrifugal pump, flexible suction/discharge manifold
system, industrial hose reel assembly with simple valve
controls, and a rugged polypropylene water tank
Manifold Delivery 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)
1” x 50’ Hose on mounted Hose Reel
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 1/4" wall polyethylene 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 three standard garden hose
valves (fill/discharge and tank drain).
Hose Reel Assembly
The Water Trailer comes standard with the MQ WT5HR
industrial Hose Reel Assembly installed. The reel holds
the 1” x 50’ construction grade reinforced hose and fire
fog-nozzle that is rated at 200 psi. Anytime the Water Trailer
Main Manifold in is the discharge position, the Hose Reel
will be active.
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 QP205SHLF Centrifugal Pump, which is used
in conjunction with the water trailer, is a
wet priming
pump
and has the capability to pump at a rate of approximately
106 gallons/minute (gpm) or 400 liters/minute (lpm) at a
maximum pressure of 100 psi (690 kPa).
Centrifugal wet priming (self priming pumps) are designed
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 affect 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 GX160 gasoline engine that incorporates a low
“Oil Alert Feature.”
Oil Alert Feature
In the event of low oil or no oil, the HONDA GX160 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.
