APP SV Submersible Stainless Steel Sewage Pump

The APP SV series is a dependable range of submersible sewage and drainage pumps designed for tough domestic, commercial, and hire-fleet applications. Built with cast iron pump casings, vortex impellers, and 304 stainless steel motor frames, these pumps offer strong durability and reliable performance in challenging wastewater conditions.
They are ideal for dirty water, sumps, cellars, light sewage, effluent, and portable site-water pumping, and each model comes with a two-year manufacturer’s guarantee.

Models, Applications and Solids Handling

There are four main models in the range: SV-150, SV-250, SV-400, and SV-750.

The SV-150 and SV-250 provide a free passage of fibrous materials up to 27 mm and are designed for soft solids and domestic wastewater. These models use a carbon ceramic mechanical seal supported by a single lip-seal in an oil chamber, and are available as automatic only.

The SV-400 and SV-750 are the larger, heavy-duty units in the series.
The SV-400 has a thermoplastic motor head cover, while the SV-750 uses a cast iron head cover. Both are equipped with cast iron impellers, making them suitable for hard solids between 35–37 mm, fibrous waste, and site-water applications. These pumps are popular in hire fleets due to their robustness and portability.

The design allows the pumps to comfortably handle common domestic wastewater solids without requiring grinder or cutter mechanisms, making the SV series efficient, cost-effective, and easy to operate. The SV series uses large pump casings and recessed vortex impellers for reliable solids handling and low maintenance.
