Multiquip QP4TE manual General Information, Application

APPLICATION

The QP4TETrash 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-270D50021gasoline 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.

GENERAL INFORMATION

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.
