Trash Pumps
Self-priming and built to pass debris, for dewatering, construction, and flood cleanup, to buy or to rent.
What kind of pump moves muddy, debris-filled water?
A self-priming trash pump is the tool for muddy, debris-filled water, because its large impeller passages and removable cover pass and clear the mud, leaves, and solids that clog an ordinary pump. It sits on the bank and primes itself from a dropped suction hose, so it suits dewatering, construction, and flood cleanup. Match the solids rating to your debris and we will size it, and rent it if the job is one-time.
What makes a trash pump different
A trash pump is a self-priming centrifugal pump engineered for dirty duty. A large priming chamber lets it re-prime after the suction hose picks up air, oversized impeller passages let solids through, and a removable front cover gives fast access to clear a jam or reset the wear plate. Semi-trash models handle lighter debris and finer sediment, while full trash models pass larger, harder solids. The pump stays dry on the bank while only the suction hose goes into the water.
Where trash pumps go to work
- Construction dewatering of excavations, trenches, and footings.
- Flood response and storm cleanup where water carries debris.
- Pit, sump, and pond pumping loaded with mud and sludge.
- Bypass and temporary transfer during repairs or shutdowns.
Sizing a trash pump
- Solids rating. Match the largest solid and the debris type to the pump; full trash for hard solids, semi-trash for lighter debris.
- Flow and head. State the volume to move and the total dynamic head including hose friction and lift.
- Suction lift. Self-priming has a practical lift limit, so note how far above the water the pump will sit.
- Hose and strainer. Size suction and discharge hose to the pump and use a strainer sized to the solids.
- Duty and drive. Confirm engine or motor drive and run hours for the job.
Buy or rent
For one-time dewatering, flood response, or a short project, renting a sized trash pump gets equipment on site fast with no capital outlay. For recurring duty, owning the pump plus a service plan is usually the better long-run cost. We quote both, and for temporary needs see pump and blower rentals.
Service and wear
The wear plate, the impeller, and the suction seal are the parts that decide trash pump performance, so lost prime or falling flow usually points to an air leak in the suction, a worn impeller, or an opened-up wear plate clearance. Resetting the clearance and sealing the suction restore most of the loss. Our factory-trained technicians rebuild trash pumps; start at pump repair.

Trash pump questions, answered first
What is a trash pump used for?
A trash pump is a self-priming surface pump built to move water heavily loaded with mud, leaves, sludge, and solid debris, which makes it the go-to for dewatering, construction sites, flood cleanup, and dirty sumps. Its large impeller passages and removable cover let it pass and clear solids that would clog an ordinary pump. Because it sits above the water and self-primes, you can set it on the bank and drop a suction hose in.
How big a solid can a trash pump pass?
The solids a trash pump can pass depends on the model, so match the pump rating to the largest debris in your water rather than guessing. Full trash pumps handle larger, harder solids while semi-trash pumps suit lighter debris and finer sediment. Undersizing the solids rating is the top cause of clogging, so describe the debris and we will match the pump.
Should I buy or rent a trash pump?
Rent a trash pump for one-time dewatering, flood response, or a short project, and buy when the duty is recurring enough to justify owning the equipment. Rental gets a sized pump on site fast without a capital outlay, which suits construction and emergency work. For steady, repeated dewatering, ownership plus a service plan is usually the better long-run cost. We can quote either path.
Why is my trash pump losing prime or flow?
A trash pump that loses prime or flow usually has an air leak in the suction line, a clogged or worn impeller, or a worn wear plate that has opened up the clearance. Self-priming depends on a sealed suction and the priming chamber holding liquid, so a loose fitting or cracked hose breaks it. Checking the suction seal, clearing the impeller, and resetting the wear plate clearance restore performance.
