Engine-driven trash pumps (trailer mounted) are available in sizes ranging from 2" to 12". They can be purchased on their own but are often sold with the trailer. Their portability makes them a valuable asset in many industries, especially those that work with liquid, slurry, and/or debris.
Features vary depending on size and brand name, but there are some essential components that one should always look for when purchasing an engine-driven trash pump. These include a 6000 gallons per minute (GPM) max discharge rate and up to a 400-foot head, a three or four-cylinder diesel engine, and a large clean-out port to remove debris. The size of the pump, from 2 inches up to 12 inches, yields different types of capacity and pressures. The pumps should also have a double Silicon Carbide seal, and the discharge port should be able to rotate in 180-degree increments and be replaceable.
Trailer mounted engine-driven trash pumps should ideally be DOT-compliant. This means that the trailer would need to have fenders, lighting, e-brakes, a swivel jack, and either a ball hitch or a pintle eye coupler. The fuel tank should be built in accordance with DOT regulations and feature fuel lines and mounting brackets.
There are several important specifications to look out for when buying a trailer mounted engine-driven trash pump to ensure that it will be suitable for the project in question. Solid handling capabilities range from two to three inches, which is important to note if the pump will be used to process water or other liquids that may contain solids. The maximum liquid temperature should also be noted to ensure hot liquids do not damage the pump or the hoses attached to it. A suction hose assembly and discharge hoses are handy optional features that can be purchased from some dealers. Pumps that meet EPA standards may have EPA certification, which is a plus for companies that put a premium on sustainable operations.
Only a factory-trained technician should transport, set up, operate, and maintain an engine-driven trash pump. Users should always follow the manufacturer's instructions and ensure the pump is used in accordance with all applicable health, safety, and environmental regulations. The pump should not be used for jobs outside its designed limitations and the pump and accompanying hoses should be drained before prolonged storage. Regular maintenance is a must, but the pump should be turned off and allowed to cool down before servicing or repairs.
Common pump problems include failure to prime and failure to operate at the proper speed. Some reasons why a pump may not start include an air leak, blocked line, loose diaphragm, or low engine speed. Some solutions to these problems include tightening suction line joints and hoses, cleaning the hose and strainer, removing debris from the valve and seat, and increasing the throttle. If the pump does not run at the proper speed, a user should clean debris from the valve and seat, replace old hoses and check valves, and increase the throttle.
Cities and contractors typically use engine-driven trash pumps to bypass sewage facilities, remove water from a specific location, or for general water transfer over long distances. They are also used on construction sites where temporary pumping is required while a lift station is being built or repaired.
