Double-diaphragm pump Evora LDE 1000

for alkalisacidfor solvents

Overview
The LDE 1000 VA-TPE/PTFE combines a V4A stainless steel housing with TPE-PTFE sandwich diaphragms, providing chemical resistance for light acids, alkalis, alcohols and solvents. An ATEX/Ex version is available for potentially explosive atmospheres.

Application & benefits
This air-operated double-diaphragm pump is suited where chemical resistance alongside a robust metal design is required—typical in chemical processing, industrial cleaning and as a cost-effective option for non-hygienic food-industry applications. The stainless steel housing gives increased mechanical stability under demanding conditions.
