Diaphragm and piston pumps
Our metering pumps (reciprocating positive displacement pumps) offer maximum metering accuracy and are the benchmark for safety, reliability and efficiency, especially when the conveyance of critical fluids is at stake. Within our selection, we offer both diaphragm and piston pumps.
High performance, high pressure, high reliability
The LEWA triplex, LEWA ecoflow and LEWA plunger pumps are the industry benchmark for reliable, durable and energy-efficient pumps in high-pressure process technology. All components are designed and optimized for the appropriate application.
Range of flow rates from a few l/h to several hundred m³/h
A relatively rigid compression curve makes these pumps ideal as feed pumps and metering pumps within their extensive range of flow rates. They are frequently a cost-effective alternative, especially in the food, pharmaceutical, and biotechnology industries, as well as for low pressure requirements.
Are you looking for efficient, cost-effective transportation for large amounts of fluid?
If so, centrifugal pumps or rotary pumps could be the right choice for you. LEWA distributes centrifugal pumps from various manufacturers and for many different applications – the lowest temperatures (–162 °C), highest viscosities and abrasive fluids are routine for us.
Double diaphragm displacement pumps, universal and economical
Hermetically sealed air-operated diaphragm pumps are versatile and easy-to-use industrial pumps and often present an economical solution when fluids must be conveyed in non-critical processes with lower pressure requirements.
On the basis of their functional principle, pumps can be divided into two main groups.
Pumps are used in different applications in various industries. In most cases, liquid should be conveyed or dosed. To ensure reliable and smooth operation at all times, the relevant pump technology must be adapted to the prevailing framework conditions.
