MULTIQUIP QP3TH Operation And Parts Manual page 15

Figure 3 shows key components of the QPT3H.
1. Pump — The model QP3TH is a 3-inch trash pump
used in general dewatering applications. Typical
dewatering applications consist of: manholes, septic
tanks, ponds, ditch water, silt water, muddy water, and
water with debris.
2. Fill Cap — Prior to operation, the pump casing MUST
BE filled with water. Remove this cap to add water to
the pump. After the initial prime, a sufficient amount of
water will be retained in the casing so that the operator
will not need to re-prime later.
3. Discharge Ports — The pump is equipped with left
and right side discharge ports. These ports are 3" male
NPT thread and can accommodate discharge hose or
pipe. Quick disconnect (Cam & Groove lock) hoses
can be fitted onto the discharge ports with an optional
coupler (A300A).
4. Discharge Hose — This pump is fitted with 3" male
NPT thread discharge ports and can accommodate
either threaded discharge hose or pipe. Quick
disconnect (Cam & Groove lock) hoses can be fitted
onto the discharge ports with an optional coupler
(A300A). Make sure hoses lays flat and are not kinked.
Contact MQ Sales Department for ordering information.
5. Suction Port — This pump is fitted with a 3" male
NPT thread suction port and can accommodate either
a threaded or quick disconnect (Cam & Groove lock)
hose. For quick disconnect connections, an optional
coupler (A300A) is necessary. Contact MQ Parts
Department for ordering assistance.

6. Suction Hose — Use only recommended suction
hoses. This pump is fitted with a 3" male NPT thread
suction port and can accommodate threaded or quick
disconnect (Cam & Groove lock) suction hose. Cam
& Groove lock hose can be fitted onto the suction
port with an optional coupler (A300A). Make sure
the suction hose is not kinked. Contact MQ Sales
Department for ordering information.
7. Clean-out Cover — TWhen the pump is subjected to
applications where large quantity of debris is present,
it may be necessary to clean out the casing cavity of
large rocks and such that have not passed through
the pump. To open and gain access to the pump's
clean-out cavity, loosen the four Locking Knobs (item
9). Grip the cover handles and twist counterclockwise.
Once the cover is clear of the four knob fasteners, pull
the cover out towards you.
8. Drain Plug — After usage, and for storage, remove
this plug and drain all water from the pump casing.
9. Locking Knobs — Turn both knobs counterclockwise
to release cover. Turn clockwise to secure clean-out
cover.
10. Strainer — Always attach a strainer to bottom side of
the suction hose to prevent large objects and debris
from entering the pump. Strainer should be positioned
so that it will remain completely under water. Running
the pump with the strainer above water for long periods
can damage pump.
