Self-Priming Pumps

Supplier: Pumpability

BBA Pumps from the Netherlands offer a range of heavy-duty cast iron, bronze and stainless steel self-priming pumps for dirty water and raw-sewage applications.


The pumps may be direct mounted to electric motors or long-coupled to electric motors or diesel engines.

Diesel-driven units can be supplied with acoustic canopies for noise reduction in residential areas.

Applications in Process and General Industry

Self-priming pumps are suitable for many applications in general process industries as an alternative to submersible pumps, such as in emptying tanks or sumps of process or waste products.

Applications in Water and Wastewater

BBA self-priming pumps can be used in raw water supply from creeks and rivers where there may be wide fluctuations in water levels and the risk of conventional pumps loosing prime.

The pumps are also used for pumping waste water or raw sewage.

In raw sewage applications the pumps are fitted with a knife blade in the front wear plate to cut any fibrous material entering the pump.

Applications in Construction

BBA self-priming pumps are built to handle dirty-water on construction sites. As such one of their main uses is in construction site dewatering from constructed or natural sumps or pits.

The pumps are available with electric or diesel drive, including acoustic enclosures.

For wellpoint dewatering the pumps are available with air separation systems and diaphragm type vacuum pumps for simultaneous air and water handling.

The diaphragm type vacuum pump is driven directly from the pump shaft, is unaffected by water carry-over and is a very efficient maintenance-free vacuum pump.

Also for wellpoint dewatering or water supply, the BBA piston pumps are very efficient for temporary or permanent installations.

Applications in Mining and Mineral Processing

The robust construction of BBA self-priming pumps and their ability to handle dirty-water make them very suitable for mine dewatering.

Special high-head versions of the pump have the suction from behind the mechanical seal to avoid high-pressure and excessive wear on the seal when pumping dirty water.
