QP- 40TE — GENERAL INFORMATION
APPLICATION
The
QP-40TE Trash Pump
is designed to be used for de-
watering applications. Both the suction and discharge ports on
the QP-40TE pump use a 4-inch diameter opening, which allows
the pump to pump at a rate of approximately 425 gallons/minute
(gpm) or 1,600 liters/minute (lpm).
Self priming pumps are designed to purge air from the suction
line and create a partial vacuum in the pump body. The reduced
atmospheric pressure inside the pump allows water to flow
through the suction line and into the pump body. The centrifugal
force created by the rotating impeller pressurizes the water and
expels it from the pump.
Power Plant
This trash pump is powered by an 11 horsepower air cooled 4-
stroke, single cylinder
ROBIN EX- 2
70D gasoline engine that
incorporates a low "
Oil Alert Feature
"
Oil Alert Feature
In the event of
low oil
or
no oil
, the ROBIN EX- 270D 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.
Trash Pump
Trash pump derive their name from their ability to handle a greater
amount of debris and solids than standard centrifugal pump.
These types of 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.
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, pump
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.
