Version with Inducer
- Inducer is an additional upstream impeller of screw type which provides very low NPSH values
- Design of the inducers is selected according to specific application range of Customer.
KRPV
- Vertical volute-casing pumps for wet or dry installation with most different submersion depth up to 8 m
- Shaft on drive side with robust pair of angular ball bearings of long lifetime running in the pump in maintenance-free slide bearings
- Slide-bearing locations are lubricated by means of liquid to be pumped via lubrication piping.
- Bearings with oil or grease lubrication, optionally we can provide bearing cooling.
