The heavy duty submersible sewage pumps are made for wastewater that may contain soft solids, fiber, sand, and daily drainage waste. The whole pump is placed in the liquid, so priming is not needed. This makes the pump useful in deep tanks and wet wells where suction height can be a problem for surface pumps.

For heavier work, heavy duty submersible sewage pumps usually use a strong casing, larger flow passage, and mechanical seal to reduce leakage risk. The cable, seal chamber, and bearing space need to be checked before long service. In municipal stations and factory drainage pits, these products are often chosen because they start quickly, take less room, and can be lifted out for repair. A good match of head, flow, and solids passage helps these products avoid overload and blocking.
