PS/PD series vacuum pump- Chemical pharmaceutical industry

Project Introduction

A chemical enterprise originally used the water ring pump. After using our dry screw pump, the economic benefits come from two aspects: organic solvent recovery and water saving.

1.      Condensate recovery organic solvent: after distillation, it can be returned to production and use, which reduces the use of solvent accordingly, and improves the recovery solvent quantity to achieve the effect of saving cost.

2.      Water saving: dry screw vacuum pump basically does not consume water.

In the pharmaceutical industry, more and more manufacturing companies choose to use dry screw vacuum pumps.
