GENERAL INFORMATION

The MQ62TDD trash pump is a self-priming trash pump powered by a 29 horsepower air-cooled, 2-cylinder, four stroke Deutz diesel engine. Both the intake (suction) and discharge ports on the pump incorporate a 6-inch diameter opening, which allows the pump to discharge at a rate of approximately 1,083 gpm or 4,100 lpm.

This is a self-priming pump design, the pump casing must be filled with water before the pump can be used.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. This pump can handle solids up to 2- inches (51 mm). 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 (7.6 meters) 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

NEVER place the pump on soft soil. 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.

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 pump has been design for easy removal that allows for easy access to the wear plate and impeller for cleaning and servicing.

HOSES

Suction and discharges hoses 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.

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 to the part list in section 2 of this manual for a complete list of accessories
