MQ600TD80 — GENERAL INFORMATION
The MQ600TD80 Trash Pump is a self-priming centrifugal trash
pump powered by a 80 horsepower air-cooled four stroke Deutz
diesel engine. Both the intake (suction) and discharge ports on
the MQ600TD80 incorporate a 6-inch diameter opening, which
allows the pump to charge as needed at a rate of approximately
1,600 gpm or 6,055 lpm.
This is a self-priming pump design and the pump casing must
be filled with water before starting operation. 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. These pumps generally handle solids up to 1/2 the size
of the discharge opening making them less likely to clog. Also
trash pumps are capable of handling water with 25% 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 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
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. In addition, place chock blocks behind
each wheel to prevent the trailer from rolling.
NEVER place the pump on soft soil . The suction hose 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.
.
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.
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 MQ600TD80 has been design for
easy removal that allows for easy access to the wear plate and
impeller for cleaning and servicing.
In order to comply with local laws regarding spark arresters,
consult the engine distributor or the
local Health and Safety
Administrator.
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 overheating. 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 fueling! Failure to follow the safety guidelines
described in the Rules for Safe Operation section of this manual
and the Deutz Engine Operator's Manual could result in severe
injury or death.
Accessories
Multiquip offers a complete line of fittings, hoses, and clamps to
properly connect the pump to match various job conditions. Refer
