Self-priming rotary displacement pumps in a compact range with external bearings without touching medium. For aggressive media also.
Advantages for Users
Wide range of applications
Self-priming
Pumped capacity proportional to speed
Compact construction
Direct drive without speed-reducer possible
Change of pumping direction - simple
Pumping elements - simple to replace
Easy maintenance
For almost all media and fluids
High viscosities possible
Low pulsations
Low noise level
Dry running possible
Constant flow on varying pressures and volumes
Very good suction performance up to NPSH
1 - 1,5 m/3 - 5 feet
Engineered 2-piece shaft and screw construction
These pumps can handle virtually any fluid, regardless of viscosity, lubricity or abrasiveness e.g. seawater, bitumen, molasses, lime, acid, caustic solution or hydrocarbon.
The W-range is a horizontal pump execution with external bearings. We distinguish from the short execution (Wzk) and the long pump execution (Wz). The short execution will be used for applications with high differential pressures. Due to the low space for the mechanical seals the choice of the seals is limited.
