KSB KWP Non-clogging Centrifugal Pumps

The KWP non-clogging centrifugal pump is a horizontal, single-stage, radially split volute casing pump designed with a back pull-out structure for ease of maintenance. It is engineered to handle a wide range of pulp, stock suspensions (up to 5% bone dry), and various fluids containing solids, making it highly resistant to clogging.

Key Features of KSB KWP Non-clogging Centrifugal Pumps

Robust Design: Reinforced, axially adjustable bearing assembly for extended service life.
Flexible Shaft Sealing: Options include mechanical seals (integrated into the casing cover) or gland packing, suitable for various operational conditions.
Wear-Resistant Internals: Even standard cast iron models feature wear-resistant components such as ERN (nickel cast iron) impellers and wear plates.
High Efficiency: Channel-type impeller design ensures optimal hydraulic performance.
Easy Maintenance: Back pull-out design allows the rotor to be removed without disconnecting the piping.
Dry Shaft Design: The shaft does not contact the medium, eliminating the need for special shaft materials.
Certified Quality: Manufactured under ISO 9001 certified quality management.
