The new ecosmart series of diaphragm metering pumps (photo) is said to offer the best price-performance ratio in its class (80 bar, 120°C, 300 L/min), and meters reproducibly and precisely thanks to the proven variable eccentric drive. Different stroke frequencies of the drives allow adaption to diverse fluids and process requirements. The design of the hermetically tight diaphragm pump is based on the manufacturer’s well-known technology using the PTFE sandwich diaphragm with diaphragm monitoring, the patented diaphragm-protection system and optimized check valves. The pump also complies with API 675 safety standards. — LEWA GmbH, Leonberg, Germany
