GENERAL INFORMATION
APPLICATION
The
QP4TE Trash Pump
is designed to be used for de-watering
applications. Both the suction and discharge ports on the QP4TE
pump use a 4-inch diameter opening, which allows the pump to
pump at a rate of approximately 528 gallons/minute (gpm) or
2,000 liters/minute (lpm).
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 "
without tools
" and easily
cleaned when clogged.
Power Plant
This trash pump is powered by a 9 horsepower, air-cooled,
4-stroke, single-cylinder,
ROBIN EX-270D50021
gasoline
engine that incorporates a low "
Oil Alert Feature
".
Oil Alert Feature
In the event of
low oil
or
no oil
, the engine has a built-in oil
alarm engine shut-down feature. In the event the oil level is low
the engine will automatically shut-down.
Suction Lift
This pump is intended to be used for dewatering applications
and is capable of suction lifts up to 25 feet at sea level. For
optimal suction lift performance keep the suction hose or line as
short as possible. In general always put the pump as close to the
water as possible.
Pump Support
The pump should always be placed on
solid stationary
ground
in a level position.
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.
NOTE
Please contact your nearest authorized MQ
dealer for any accessories that your pump
may require.
