What Is a Trash Pump?
A trash pump is a centrifugal pump designed to move dirty water containing debris and suspended solids that could clog a conventional clear-water pump. Larger internal passages and durable wear components allow the QP4TH to operate effectively in demanding construction, drainage, and dewatering environments.
The QP4TH is designed for agricultural applications, construction sites, dirty water, emergency response, excavations, farms, floods, irrigation, jobsite drainage, mining, municipalities, standing water, quarries, water departments, and water supply from lakes and rivers.
Understanding Pump Flow Rate and Head
Trash pumps are commonly selected using flow rate (GPM) and total head. Flow rate represents how much water the pump can move per minute, while total head represents the elevation and system resistance the pump can overcome.
The QP4TH delivers up to 555 GPM with a maximum head of 92 feet and maximum pressure of 40 PSI. Actual pumping performance will vary depending on suction lift, discharge elevation, hose diameter, hose length, fittings, bends, and water conditions.
Dual 4-Inch Discharge Connections
The QP4TH features a 4-inch NPT male suction connection and dual 4-inch NPT male discharge ports. The replaceable dual-discharge design provides additional flexibility when positioning discharge hoses and configuring the pump for different dewatering applications.
Honda Gasoline Engine
The QP4TH is powered by a Honda GX340 337cc gasoline engine rated at 10.7 HP. The air-cooled, 4-stroke, single-cylinder OHV engine operates at 3,600 RPM, uses recoil starting, and includes low-oil shutdown protection to help protect the engine if the oil level becomes too low.
Heavy-Duty Trash Handling
The QP4TH can handle spherical solids up to 2 inches in diameter. Its semi-open ductile iron impeller, cast iron volute, sand-cast aluminum casing, silicon-carbide mechanical seal, and large cleanout cover are designed for dependable operation in abrasive and debris-laden water.
Fuel and Runtime
The latest 2026 QP4TH data sheet specifies a 1.6-gallon fuel tank, fuel consumption of approximately 0.82 gallons per hour, and approximately 1.95 hours of runtime under rated operating conditions.
Warranty
The latest Multiquip QP4TH data sheet lists a 2 Year warranty from the date of purchase for the QP4TH pump, a 3 Year warranty for the Honda GX340 engine, and a 3-month warranty for hoses. Always verify current warranty terms, fuel requirements, maintenance requirements, hose specifications, and operating conditions before use.
