d. Electric-Motor Driven Pump. The electric motor driven pump (fig. 1-4.1) is a self-priming unit with the im-
peller mounted on the extended shaft of the electric motor. Both the pump and motor are mounted on a base plate
to facilitate removal and use in auxiliary pumping operations.
e. Engine. The engine (figs. 1-2 and 1-3) is a 1 -cylinder, 4-cycle, air cooled, hand cranked, Wisconsin gasoline
engine, Model MBKND. A radio shielded magneto supplies the ignition spark, and a governor controls the engine
speeds by varying throttle openings to suit pump loads. A gasoline tank of 1 gallon (3.875 liter) capacity is provided.
f. Electric Motor. The electric motor is explosion-proof. The motor operates on 28 volts dc (direct current) and
is rated at 1.5 hp (horsepower). The electric motor driven pump assembly requires two cables (Fig. 1-4.1).
NOTE
Electric Motor Driven Pump requires slave receptacle mounted
at right rear side of cab.
g. Filter/Separator. The filter/separator (figs. 1-2 and 1-3) is a vertical, 50 gpm unit designed for maximum
operating pressure of 75 psi (pounds per square inch) (5.2725 kg/sq cm). Both solids and water (free and entrained
water) are removed from the fuel through coalescing and filtering media of the elements inside the filter/separator,
The filter/separator has four canisters and filter elements, two pressure gages, sight glass, and two drains. Solid
contaminants are deposited in the elements. The emulsified or entrained water coalesces within the elements and
settles to the deck plate where it is removed, periodically, through the upper drain, as free water. Clean product builds
up in the shell, and is pumped to the hose reels. Refer to figure 1-5 for flow direction of the pumped product.
1-7. IDENTIFICATION AND TABULATED DATA.
a. Identification. The tank and pump unit pumping assembly has the following identification and instruction
plates.
(1) Tank and pump unit manufacturer’s plate. Located at the lower center of the front frame of the pumping
assembly. It specifies the nomenclature, manufacturer, model number, serial number, specification number, con-
tract number, date manufactured, weight empty, weight with 600 gallons (2271 liters) of gasoline, and weight with
1200 gallons (4542 liters) of gasoline.
(2) Pump manufacturer’s identification plate. Located at the left side of pump housing. It specifies make,
model, serial number, and National Stock Number of the pump and engine assembly.
(3) Electric motor pump assembly. Located on the pump end of the skid. It specifies the nomenclature,
manufacturer, model, serial number and rating (see figure 1-4.1).
