A trash pump is designed to move water that contains debris such as leaves, twigs, sand, or small stones. They are commonly used on construction sites, farms, and for flood clean-up, where the water is too dirty for a standard clean-water pump.
A trash pump is a heavy-duty water pump with a larger impeller and volute, allowing it to pass solids without clogging. It’s built to handle dirty water applications where standard pumps would block or fail.
A semi-trash pump is suitable for water with small amounts of debris, such as leaves or sand, but not large solids. They are often used for draining pools, ponds, or irrigation ditches where the water isn’t perfectly clean but not heavily contaminated.
The output of a 3-inch trash pump varies by model, but many can move between 800 and 1,200 litres per minute. Factors such as pump design, engine power, and hose length will affect performance.
In pump specifications, Q refers to the flow rate — the volume of water the pump can move over a given period, usually measured in litres per minute (L/min) or cubic metres per hour (m³/h).
A double impeller water pump has two impellers stacked in series. This design increases the pump’s pressure output, making it ideal for applications that require high head pressure, such as firefighting, long-distance water transfer, or pumping uphill.
