Applications of Wilden Chemical Pumps in Modern Industry

Introduction

Wilden is a global leader in air-operated double-diaphragm (AODD) pumps, offering robust and versatile solutions for handling a wide range of liquids – including highly corrosive and hazardous chemicals. Through its UK distributor, Air Pumping Ltd, Wilden provides tailored pumping systems designed to ensure safety, efficiency, and durability across many industrial sectors.

Key Technical Features for Chemical Applications

Before diving into applications, it’s worth highlighting the technical strengths that make Wilden pumps particularly suited for chemical handling:

  • Corrosion-resistant wetted materials (PTFE, PVDF, polypropylene, stainless steel 316L, exotic alloys) for aggressive chemicals.

  • Seal-less diaphragm design, eliminating mechanical seal failures and reducing leakage risks.

  • Air-powered operation, inherently safe in flammable or explosive environments (ATEX-certified options available).

  • Energy-efficient air distribution systems (e.g., Pro-Flo® SHIFT) that reduce air consumption by up to 60%.

  • Capability to handle viscous, abrasive, or shear-sensitive fluids without damaging product integrity.
