Lesson 1/Learning Event 1
In this learning event, we will discuss the major components, special tools,
and the procedures required for performing new-equipment services.
Pump-unit Assembly
The pump-unit assembly is a skid-mounted unit consisting of a frame
assembly, cover panels, a gasoline engine, a fuel tank, prime-detergent tank
plumbing, pump housing, a generator, a battery, two discharge hoses on two
hose reels, a connector panel, a control panel, exhaust-pipe extensions, and
a cover. A toolbox, which is used to store on-equipment material (OEM), is
located between the two hose reels.
A suction-hose connector and two
discharge-hose connectors are on the connector panel at the back of the pump
unit.
A lifting eye with clevis is provided on top of each corner for
picking up the pump-unit assembly. The canvas cover is provided to cover
the pump-unit assembly when it is not in use.
The two exhaust-pipe
extensions are stowed on the tank-unit assembly.
The extensions are
attached to the exhausts of the engine when it is operating. The pump-unit
assembly is shown in figure 2.

The pump housing consists of a pump, a four-groove-driven pulley, a
connector for suction-vacuum gage tubing and discharge-pressure gage tubing,
a prime/eductor, piping, a discharge-pressure pipe, and a drain pipe.
