Evora LDE 025M (1/4") compressed air double diaphragm pump

Product information "Evora LDE 025M (1/4") compressed air double diaphragm pump"

The cost-effective, versatile plastic pump for chemicals, alcohols and water-based solvents

The LDE 025M in PP with an NBR/PTFE diaphragm is the cost-effective solution for compact pumping applications in chemical environments. The polypropylene housing offers good chemical resistance, whilst the PTFE-backed diaphragm design enables use with more demanding media. This makes this double diaphragm pump suitable for mild acids and alkalis, many alcohols, water-based solvents and chemically contaminated process fluids, provided they do not contain any abrasive solids. The general material characteristics of PP include good chemical and mechanical resistance, although it is not suitable for petroleum-based solvents. 

This variant is particularly well-suited to compact dosing and transfer systems thanks to its low weight, clean, oil-free operation and low maintenance requirements. For operators seeking a small diaphragm pump offering good value for money, this version is a compelling entry-level solution for the safe transfer of chemicals.

Key benefits:

  • Cost-effective version for many standard chemicals
  • PTFE diaphragm for enhanced media resistance
  • Ideal for compact chemical and wastewater applications
