W+ Sanitary Centrifugal Pump
| Manufacturer | Waukesha Cherry-Burrell |
|---|---|
| Product Line | W+ Series |
The APV W+ pump series is based on a unique hydraulic design that ensures maximum efficiency, allows for the highest hygienic standards and reduces noise and vibration. The W+ range consists of 16 standard models with pressure and flow capacities to 217psi and up to 1,760gpm. A number of special versions are available, including the Wi+ inducer pump for low NPSH applications and the Ws+ self priming unit designed to handle CIP return and other fluids with entrained air and foam.

APV Wi+ Inducer Centrifugal Pump
An Inducer is an axial flow impeller with blades that wrap in a helix around a central hub. The inducer rotates in a close-fitting housing to provide a “booster” effect in front of the main impeller.
The inducer pump is the alternative to changing the process design when NPSH availability is low. The inducer boosts the inlet pressure, and the risk of cavitation is correspondingly reduced (the NPSH required typically drops by 50-70%). When the risk of cavitation disappears, so does the risk of a large number of operational disturbances that would otherwise result – such as excessive noise, energy loss, product damage and unnecessary wear on the pump. Low suction head is a common “problem” in miscellaneous applications, e.g. when pumping products with low boiling points or in processes that involve vacuums.
The Wi+ is unique among inducer pumps, since the NPSH requirement is kept to a minimum throughout its entire operating range. The inducer further enables the Wi+ pump to handle viscous or gaseous products beyond the range of other centrifugal pumps.
APV Ws+ Self Priming Sanitary Centrifugal Pump
- 20-90% more efficient than other liquid rings due to improved fluid flow through pump.
- Performance optimised 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.
- 3A (optional) and EHEDG approved.
- Interchangeable with W+ parts. Inventory is reduced by sharing common parts.
- Less prone to damage. Small objects can pass through pump with minimal damage.
