APV series Ws+ self-priming pumps
The Ws+ structure employs a built in eccentric air screw to form the liquid ring required for its self-priming capability. The self-priming Ws+ is designed to handle Clean In Place (CIP) return and other fluids with entrained air and foam.
Consumable features:
- Type: centrifugal for beverages and liquids
- Type: self-priming
- Capacity: 30 m³/h, 50 m³/h, 90 m³/h
- Pressure range: 6 - 13 bar
The lineup: Ws+20/15, Ws+30/30, Ws+44/50
Performance
At 50 Hz, the Ws+ pump operates at a maximum pressure of 6.5 bar and a capacity of 90 m3 /h, while these values for the 60 Hz pump are 9.5 bar and 110 m3 /h.
The principle of operation
- The principle of the axial catchment ring, which is formed by an air screw and centrifugal forces.
- The propeller is located eccentrically in the housing, so that the upper part is completely covered by the drainage ring.
- The ring works as a seal, passing only the medium or air through the propeller, which prevents air entrapment.

- Fluid recirculation loop
- Impeller
- Eccentric screw
Air-screw compressor
- Air screw
- Liquid ring
Features and Benefits of the Ws+ series
- Increased performance with low energy consumption. Small objects can pass through pump with minimal damage.
- Interchangeable with W+ parts. Inventory is reduced by sharing common parts.
- 20-90% more efficient than other liquid rings due to improved fluid flow through pump. Performance optimized by matching impeller size to duty.
- Low noise level: Due to its hydraulic design the noise level of the Ws+ is significantly lower than traditional liquid ring pumps.
- 3-A and EHEDG approved.
- Perfect for CIP flushing on return line.
- Capable of entrained air pumping.
