LEWA triplex hygienic process diaphragm pumps
The first choice for challenging applications in food and biotech sectors.
Key features and benefits
Hygienic design with hermetically sealed diaphragm pump technology
The hygienic version of the LEWA triplex pump is the ideal choice for handling the most sensitive media in high pressure applications.

Hermetically tight pump technology
A sandwich diaphragm with continuous monitoring minimizes the risk of product contamination without using an extensive flush system. The patented LEWA DPS diaphragm protection system safeguards the diaphragm from overload and wear and ensures maximum uptime in the process.

Ideal for challenging food and beverage applications
All wetted components are manufactured from food grade material following FDA and EGV1935 standards. High quality surface finish and excellent cleanabillity makes the pump ideally suitable for the most sensitive fluids.

Ideal for high pressure applications in hygienic industries
With full material traceabillity, a minimized deadleg, electropolished surface finishes and the possibillity to sterilize the pump is perfectly capable of handling even the most critical media with simplified sanitation routines.

High energy efficiency and low lifecycle costs
Optimized hydraulics and durable components reduce energy use and maintenance effort, delivering efficient operation and lower lifecycle costs in hygienic processes.

Compact footprint for easy integration into hygienic plants
Its small, space‑saving design fits seamlessly into hygienic production lines, simplifying system layout and enabling flexible integration in food, pharma and beverage plants.
