Reasons to Choose the E40 High Performance 1 ½” Pump Over Traditional Units
Reduced total cost of ownership
  • Enhanced diaphragm life
  • Extended MTBF / Reduction in overall repairs
  • Low cost seal kits and replaceable valve sleeve
  • Greater air efficiency
  • Dimensional interchange with Wilden
PX400 aluminum
  • Increased performance / Flexibility
    • Flows to 123 GPM(465lpm)
    • Displacement per stroke 0.44Gal (1.67L) 

Leak-free bolted designs in:

  • Aluminum, Cast Iron, Stainless Steel

Chemical resistant air sections available

  • Stainless Steel
  • Aluminum or coated aluminum

Enhanced diaphragm styles

  • Patented Versa-Dome technology standard
  • FUSION integrated-plate PTFE diaphragm

Block competitive conversion efforts

  • Superior E40 pump is more difficult to displace
    • Greater MTBF
    • Performance / Flow (Industry Leading)
    • Limited dimensional competitors





1 ½” Pump Performance Example:
See how the E40 outperforms traditional 1 ½” pump units in the following ways:
  • Maximum Flow
  • Displacement per stroke / cycle
  • Energy consumption
  • TCO (Total Cost of Ownership)
  • MTBF (Mean Time Between Failure)






Additional E40 Features and Benefits
  • Dimensional interchangeability with PX400 Wilden aluminum unit*
  • Available with stainless steel air section
  • ATEX compliant standard
  • Many like components with the E2 bolted pumps for inventory flexibility and reduction
    • Diaphragms
    • Plates
    • Center block
    • Air chambers
    • Pilot valve
    • Valve body
E40 Value Summary

Choosing the E40 delivers customer satisfaction:

  • Lower total cost of ownership
  • Extended MTBF (Mean Time Between Failure)
  • Greater performance and flexibility
  • More product options
  • Reduces the chance of being displaced by the competition in the future once installed

The E4 and V4 clamped products are quality units, but they cannot match the performance, flexibility, and longevity of the E40 high performance product line.
