The QP60TD trash pump is a self-priming trash pump
powered by a 25 horsepower air-cooled, 3-cylinder, four
cycle KUBOTA diesel engine. Both the intake (suction)
and Discharge ports on the pump incorporate a 6-inch
diameter opening, which allows the pump to discharge at
a rate of approximately 1,109 gpm or 4,200 lpm.
This is a self-priming pump design, the pump casing must
Be filled with water before the pump can be used. The
engine drives a rotating disc with two ( or more vanes)
called an impeller that creates an area of low pressure
inside the pump. Priming is accomplished when all air is
purged from the pump and suction line allowing water to
flow continuously into the pump.
TRASH PUMP
Trash pumps derive their name from their ability to handle
a greater amount of debris and solids than standard
centrifugal pumps. This pump can handle solids up to 1.6
inches(40mm). Also trash pumps are capable of handling
water with 10% solids by weight.
The advantage of using a trash pump is that it can be
quickly and easily disassembled in the field to remove
debris in the event the pump becomes clogged.
SUCTION LIFT
This pump has a maximum suction lifts up to 25 feet (7.6
meters) at sea level. At elevations above sea level
suction lift decreases at a rate of 1 foot of suction lift per
1,000 feet of elevation. Therefore, when this pump is
being used at an elevation of 5,000 feet the maximum
suction lift is reduced to 20 feet. It is recommended that
the pump be located as close to the source as possible
to minimize suction lift.
PUMP SUPPORT
NEVER place the pump on soft soil. The pump should
always be placed on solid stationary ground in a level
position. To prevent the trailer from tipping, place blocks
under the trailer's bumper. ln addition, place chock
blocks behind each wheel to prevent the trailer from
rolling.
ELEVATION
Elevations over 3,000 feet will effect 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.
QP60TDK SERIES TRASH PUMP• OPERATION AND PARTS MANUAL — REV. #0
A general rule of thumb is that for every 1,000 feet of
elevation above sea level a pump will lose one foot of
priming ability.
For example, in Flagstaff, Arizona where the elevation is
approximately 7,000 feet, the pump would have a suction
lift of only 18 feet rather than the 25 feet at sea level.
PUMP CLEAN-OUT
The clean-out cover on the pump has been design for
easy removal that allows for easy access to the wear
plate and impeller for cleaning and servicing.
HOSES
Suction and discharges hoses or pipe connection should
always be checked for tightness and leaks. A small
suction leak in the hose or fittings could prevent the pump
from priming.
MECHANICAL SEAL LUBRICATION
The pump uses a oil lubricated mechanical seal to
prevent water from seeping into the engine. The oil in the
seal chamber lubricates the seal and prevents it
from over heating. Never operate the pump without water
in the casing as this may cause the seal to fail. (See
section on seal maintenance).
ENGINE SAFETY
Internal combustion engines present special hazards
during Operation and fuelling! Failure to follow the safety
guidelines described in the Rules for Safe Operation
section of this manual and the KUBOTA Engine
Operator's Manual could result in severe injury or death.
ACCESSORIES
QP-Pump offers a complete line of fittings, hoses, and
clamps to properly connect the pump to match various
job conditions. Refer to the part list in section 2 of this
manual for a complete list of accessories
