GENERAL INFORMATION

APPLICATION

The Multiquip QP2TH Trash Pump is designed to be used for dewatering applications. Both the suction and discharge ports on the QP2TH trash pump use a 2-inch diameter opening,which allows the pump to pump at a rate of approximately 211 gallons/minute (gpm) or 800 liters/ minute (lpm).

Trash 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.

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 "without tools" and easily cleaned when clogged.

POWER PLANT

This trash pump is powered by a 4.8 horsepower air cooled 4-stroke, single cylinder HONDA GX160 gasoline engine that incorporates a low “Oil Alert Feature.”

OIL ALERT FEATURE

In the event of low oil or no oil, the HONDA GX160 engine has a built-in oil alarm engine shut-down feature. In the event the oil level is low the engine will automatically shutdown.

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 place 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

Higher elevations 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. This is due to the “thinner air” or lack of oxygen at higher altitudes.

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. Table 3 shows suction lift at various elevations.
