LEWA ecosmart® Diaphragm metering pumps at a smart price.

LEWA ecosmart — Introduction The LEWA ecosmart diaphragm metering pump offers the best price/performance ratio in its class and meters often costly fluids with high precision. As a positive displacement pump, it operates extremely efficiently. The LEWA ecosmart's low investment and operating costs as well as its long service life and its robustness make it a winning choice. What's more, no other metering pump in this class offers the same compact dimensions – after all, every centimeter of space saved in the design and construction of a system leads to a reduction in costs. LEWA ecosmart:...

LEWA ecosmart — Advantages LEWA ecosmart. The advantages at a glance. Metering accuracy Careful, precise conveying with outstanding reproducibility. An accuracy level of at least +/- 1% is achieved at constant basic conditions. Operational safety and reliability The pump can be started up with complete reliability from any operating state. We use a PTFE sandwich diaphragm with status monitoring as standard. An integrated pressure relief valve prevents the pump from entering potential overload situations. Hermetically tight LEWA diaphragm pumps work without dynamic seals, due to their...

LEWA ecosmart — Components Robust technology and proven quality. Reliable components are one of the keys to safe processes LEWA ecosmart pumps are based on the robust technology that LEWA is renowned for. As a result, they are also easily able to fulfill the strict safety requirements of API 675 (American Petroleum Institute). The pumps use key components from LEWA's proven range – like the PTFE sandwich diaphragm with diaphragm monitoring, the patented DPS diaphragm protection system and flow efficient check valves. DPS diaphragm protection system Diaphragm pumps are used when leak...

LEWA ecosmart — Components Flow efficient check valves Operational reliability and failure risk are critically dependent on check valve quality. The valve design is therefore adapted to the specific application. Variable eccentric principle for flow adjustment For the liquid flow adjustment, LEWA uses its proven variable eccentric principle; this also enables easy operation. The stroke length is adjusted directly on the eccentric shaft. The handwheel can be used to make a linear stroke adjustment in 0.05 mm increments, either during standstill or operation. The pistons move in harmony even...
