Double-diaphragm pump Evora LDE 050M

oillubricating oilfor liquids

Product information
The LDE 050M AL-NBR is the metal version designed for oils, greases, lubricants and hydraulic fluids. Its aluminium housing provides stability with low weight, while NBR diaphragms ensure reliable sealing and resistance to mineral-oil-containing liquids. Typical applications include workshops, service centres, machine maintenance and industrial maintenance. The compact design facilitates integration and transport.

Brief advantages

• Cost-effective solution for oil-containing media and lubricants
• Suitable for industrial use and easy to maintain
• Simple installation and compact footprint
• Optional ATEX version available for explosive atmospheres
