These powerful pumps are built to handle high volumes of trash water and slurries, but they're not all created equal. The type of trash pump you choose depends on the type of water you need to pump, the portability you require and the volumes you're dealing with.
The three main categories of
trash pumps are:
1. Centrifugal pumps
Standard trash pumps have a large pump housing that can tolerate debris such as pebbles, twigs and leaves. These objects pass through the wide impeller veins with ease, but it's still important to use a strainer to avoid overworking the pump and reduce cleaning and maintenance.
2. Semi trash pumps
These pumps also use centrifugal force to draw up water, but they're better suited to less sludgy water with smaller debris. Larger objects can damage a semi trash pump, so it's important to check whether the hose has a strainer or to hire one separately.
3. Diaphragm pumps
The heavy-duty end of trash pumps, air diaphragm pumps work similar to a piston engine as they draw in water and eject it through the pump. These pumps can handle thicker sludges, slurries and chemicals, with a range of diameters available. To determine which type of trash pump is the best fit for your dewatering needs, ask yourself:
