Double-diaphragm pump Evora LDE 0250

for solventsfor wastewateralcohol

Product overview
The Evora LDE 0250 DMP 1/4\" PPT is a compressed-air driven double diaphragm pump in a chemical-resistant PP version, designed for compact process installations and for pumping light to demanding chemical media in non-Ex areas.

Construction & materials
PP housing with glass-fibre reinforced ball seats, TPE + PTFE composite diaphragms and PTFE balls/seals ensure high chemical resistance and compatibility with alcohols, water-based solvents and chemically contaminated fluids.

Typical applications
Chemical dosing and transfer, water and wastewater technology, surface treatment and other compact processes requiring an economical plastic pump with enhanced chemical resistance.

Key advantages

• Chemical resistance from PTFE wetted components
• Economical PP housing for compact installations
• Suitable for alcohols, solvents and contaminated process media
