Double-diaphragm pump Evora LDE 025M

for alkalisacidfor solvents

Product information
The Evora LDE 025M with PP housing and NBR/PTFE diaphragm is a compact, cost-effective air-operated double-diaphragm pump for chemical environments. The polypropylene housing provides good chemical resistance while the PTFE-backed diaphragm extends compatibility with more demanding media. Suitable for mild acids and alkalis, many alcohols, water-based solvents and chemically contaminated process fluids provided they do not contain abrasive solids. PP offers good chemical and mechanical resistance but is not suitable for petroleum-based solvents. The oil-free compressed-air operation enables clean transfer and low maintenance, making the pump well suited for compact dosing and transfer systems.

Applications and advantages

• Compact dosing and transfer systems where low weight is required
• Oil-free operation for contamination-sensitive fluids
• Low maintenance and simple installation
• Entry-level diaphragm pump for safe chemical transfer

Key benefits

• Cost-effective option for many standard chemicals
• PTFE-backed diaphragm for improved media resistance
• Suitable for compact chemical and wastewater applications
