W+ Pharma Model

The APV W+ Pharma pump model has been specifically developed to meet the strict hygiene and performance requirements of the pharmaceutical and biotechnology industries. The design focuses on ultra-clean operation, high efficiency, and gentle product handling.

A dedicated drain port improves cleanability and helps maintain hygienic operation. The pump is particularly suitable for critical pharmaceutical processes such as the production of Water for Injection (WFI), purified water, and de-mineralized water.

High-efficiency impellers combined with the patented APV spiral volute design ensure optimal hydraulic performance, smooth product flow, and gentle liquid transfer directly from inlet to outlet.
