PAGE 18 — AP6/AP8 SERIES TRASH PUMPS • OPERATION AND PARTS MANUAL — REV. #0 (06/11/14)
GENERAL INFORMATION
The Multiquip AP6/AP8 series pumps are automatic primeassist pumps that can handle dewatering, sewer bypass,
and wellpoint applications.
The AP6/AP8 series pumps use a vacuum pump to remove
the air. This becomes important in certain applications such
as long suction hose runs or multiple suction points (such
as wellpoints). In these cases, high volumes of air enters
into the pump.
The AP6/AP8 series pumps use direct-drive vacuum pump
to efficiently remove very large volumes of air quickly to
obtain the priming necessary for these special applications.
The AP6/AP8 series pumps are very useful when you have
to move a lot of water fast.
IMPELLER
The impeller used on the AP6/AP8 series pumps has a
patented design to eliminate cavitation. It is a closed 2-blade
spiral, smooth flow, open, non-clog impeller, designed to
handle up to 3 or 4 inch solids depending on pump model.
The impeller pulls water directly into the pump from the
priming tank, reducing friction losses, and then pushes
it out the volute discharge. This design does not cause
turbulence normally found in centrifugal pumps.
WEAR PLATE
In conjunction with the impeller, the wear plate gives a
perfect match for great pump performance and durability.
The wear plate can be fully adjusted up to .6 inch (15 mm)
for wear.
PRIMING SYSTEM
The vacuum system is innovative, simple, yet rugged and
dependable. It uses direct drive which means no belt failure
and with only one moving part, means no maintenance.
It uses liquid-ring design with a closed water system.
Separate oil bath lubrication, for the seal and bearings with
oil reservoir, can run dry without damage. It operates quietly
with no pollution or unwanted discharge noise.
FLOAT AND BACKFLUSH (PRIMING TANK)
The priming tank float is a one-piece welded construction,
rubber valve seat, self-aligning rubber hinge. This design
increases reliability. The backflush valve allows for cleaning
of the suction strainer or wellpoint heads while the engine
is running.
FUEL SYSTEM
The AP6 and AP8 series pumps have fuel tanks integrated
into the trailer. These fuel tanks provide each pump with the
capability for continuous running for long-term jobs. There
are two corner fuel drains to check the condition of the fuel.
AP6 Series Fuel Tank
Fuel tank capacity for the AP6 series pumps is 50 gallons
(189 liters) with a run time of 28 hours @1800 rpm or 39
hours @1600 rpm.
AP8 Series Fuel Tank
Fuel tank capacity for the AP8 series pumps is 55 gallons
(208 liters) with a run time of 28 hours @2000 rpm.
FRAME AND TRACKBAR SYSTEM
The TrackBar system allows for the easy addition of jack
stands, fenders, axle, lifting bail, and other options.
This allows for fast and easy positioning of the jack stands
on the job site to fit the application, or to add subtract jack
stands as required. The removable, retractable towing
tongue minimizes storage requirements.
VOLUTE
The pump volute has an external inspection/clean-out cover
to inspect or clear the impeller. The pump shaft bearings
and mechanical seal are run in independent oil baths for
low maintenance.
LOFA ENGINE CONTROL PANEL
This control panel provides five engine status gauges (oil
pressure, tachometer, high coolant temperature, hour meter
and volt meter) along with engine shutdown capability in
the event of low oil pressure, high coolant temperature, and
alternator belt breakage.
An optional auto-start module is also available with float
switch capability which is designed for the automatic startstop of the pump. Additionally, audible and visual alerts
signal engine restarting through a control panel alarm and
beacon attachment.

FLOAT SWITCHES (AUTO MODE)
CONTACTS
Mechanical Float Switch
For unattended operation of the pump two mechanically
activated float switches will be required. These float
switches can be connected directly to EP250 control box
via a 4-pin connector located at the rear of the control box.
When the pump is placed in AUTO mode, the float switches
will allow the pump to start and stop depending on the
length of the tether.
How It Works
The mechanical float switch control will turn ON (closes)
when the float tips 45° above horizontal, indicating a high
level. It turns OFF (opens) when the float switch drops
45° below horizontal. Reference Figure 12 and Figure 13.
Maximum pumping range is 120 degrees. See Figure 11
below.
Pumping Range
The pumping range of the pump is determined by the float
switch tether cord. Use Table 7 as guide line to determine
your required pumping range. Pumping ranges are based
on non-turbulent conditions. Range may vary due to water
temperature and cord shape. Please note as the tether
length increases, so does the variance of the pumping
range.
Design Features
Float switch housings are constructed of high-impact,
corrosion resistant polypropylene with mechanically
activated, snap action contacts.
Suitable for most liquid environments.

DANGER - Fire/Explosion
NEVER fill the fuel tank while the engine
is running or in the dark. Fuel spillage on
a hot engine can cause a fire or explosion.
If fuel spillage occurs, wipe up the spilled
fuel completely to prevent fire hazards.
1. The fuel tank used with this pump has a built in fuel
gauge (Figure 19) within the tank. Read the fuel gauge
to determine if the fuel level is low.

2. Handle fuel in a safety container. If the container does
not have a spout use a funnel.
F
BATTERY CABLE CONNECTION
ALWAYS make sure the battery cables are properly
connected to the battery terminals. The RED cable is
connected to the positive terminal of the battery, and the
BLACK cable is connected to the negative terminal.
PUMP PLACEMENT
1. Read safety instructions at the beginning of manual.
2. Place pump on secure level ground as near to the
water as possible.
3. Deploy all four trailer jack stands to level the pump. If
possible place chock blocks underneath each wheel
to prevent the pump from rolling.
SUCTION/DISCHARGE HOSES CONNECTIONS
DANGER -High Pressure
PVC discharge hoses and thin-walled
rubber hoses can easily fail at the end
of the hose fittings. Leaks from the
hoses can cause high-pressure liquid
to be discharged, causing dangerous
conditions. Make sure pressure rating of hoses exceeds
the pump maximum pressure to prevent hose failure.
3. If the fuel level is low, fill (Figure 20) with recommended
type diesel fuel as referenced in Table 3. DO NOT fill
fuel tank beyond capacity.
FUEL FILLER
PORT
DIESEL FUEL
Figure 20. Refueling
4. Pay attention to the fuel tank capacity when replenishing
fuel. Refer to the fuel tank capacity listed in Table 4,
Trailer Specifications.
5. Tighten fuel tank cap securely after filling.
1. Check that the suction and discharge hoses (Figure 21)
are securely attached to the pump via Bauer™couplers
and are not restricted.
2. Place each hose so that it lays as straight as it is
possible on the ground. Remove any twists or sharp
bends from hose which may block the flow of water.
3. If using a light weight discharge hose, it should be
anchored to avoid movement with high flow or high
pressure water. Always use a suction hose or pipe that
matches the size of the pump inlet to insure optimum
performance and reduce the risk of damage to the
pump.
NOTICE
If.t is recommended that the discharge hose or pipe
match the size of the pump outlet to reduce friction as
much as possible. Using a discharge line that is larger
than the pump outlet will reduce friction and improve
