Evora LDE 050M (1/2") double diaphragm air-operated pump

Product information "Evora LDE 050M (1/2") double diaphragm air-operated pump"

Economical double diaphragm pump for standard chemicals

The LDE 050M PP-TPV is the cost-effective solution for the safe transfer of light acids, alkalis and water-based solvents. The polypropylene housing combined with robust TPV diaphragms (Santoprene) ensures reliability in daily operation, even with demanding media.

Typical applications can be found in wastewater treatment, surface finishing and the chemical process industry, where clean, oil-free pumping is required. Thanks to its low weight and compact design, the pump can be flexibly integrated into mobile or stationary systems.

Brief advantages:

  • Cost-effective plastic design for standard media
  • Oil-free, low-maintenance operation
  • Ideal for water treatment and electroplating processes
