Wilden Diaphragm Products

Integral Piston Diaphragms (IPDs)

Increase Efficiency and Save Labor Costs
Greater Flow Rates, Faster Installation and Easier Cleaning

Wilden PTFE Integral Piston Diaphragm with Cutaway, AODD pumps, AODD diaphragms, air operated double diaphragm, Wilden diaphragm

Wilden’s IPDs offer safe, clean and reliable product transfer with no product entrapment areas to minimize product contamination and risk liabilities. These diaphragms reduce labor with their clean-in-place (CIP) capabilities provided by its smooth, contoured shape and no outer metal plate. No inverting of the diaphragm is required. IPDs have greater durability and flex life and are compatible with existing shafts and supporting hardware. FDA-compliant diaphragms are available.

Types of IPDs:

1. PTFE IPD

  • Superior product containment and chemical resistance
  • Fewer parts to greatly minimize contamination points
  • Prevents product entrapment with its smooth, contoured shape
  • Saves time and labor with faster cleaning in sanitary and ultra-pure applications

Ultra-Flex™ Diaphragms

Ultra Flex Diaphragm, AODD pumps, AODD diaphragms, air operated double diaphragm, Wilden diaphragm

Innovative Engineering Stretches Diaphragm Life

Wilden developed Ultra-Flex™ technology to make it the longest-lasting rubber compound diaphragms in the industry. Their “operational” convolute shape minimizes stress concentration throughout entire stroke providing the key to long diaphragm life.

  • Utilizes longest-lasting rubber-compound diaphragm in the industry
  • Maximizes diaphragm material movement while decreasing diaphragm loading and stress concentration
  • Controlled fabric placement decreases tensile loading to further reduce stress
  • Increased abrasion resistance with corrosive materials

Available in Buna-N, EPDM, Neoprene, Viton®

Available Sizes

  • 38 mm (1-1/2")
  • 51 mm (2")
  • 76 mm (3")
  • 102 mm (4")

EZ-Install Diaphragms

Wilden TPE EZ-Install Diaphragms, AODD pumps, AODD diaphragms, air operated double diaphragm, Wilden diaphragm

Cut Installation Labor and Downtime

EZ-Install TPE Diaphragms are a very convenient and greatly simplified direct replacement of traditional diaphragms. With EZ-Install Diaphragms, maintenance staff does not need to invert the diaphragm during the installation process to greatly reduce installation time, lower maintenance costs, enhance safety and improve uptime.

  • Eliminate headaches, decrease downtime and cut the costs of diaphragm replacement
  • Reduce installation labor time and costs — No inverting of the diaphragm required for faster installation with fewer people
  • Get the pump up and running in half the time (about 20 minutes)
  • Convolute shape allows quick, easy installation and minimizes risk of injury
  • Same performance and durability as traditional diaphragms
  • 100% compatible with existing hardware
  • Options to comply with FDA standards for food processing

Available in Wil-Flex, Saniflex, Polyurethane and Geolast®

Available sizes for use in all Wilden AODD pumps:

  • 38 mm (1-1/2”)
  • 51 mm (2")
  • 76 mm (3")
  • 102 mm (4")
