LEWA ecosmart^®: The clever idea for plant engineering

When discharging or metering fluids, industrial system operators must often observe rigid safety and environment aspects and meet the requirements of individual processes.

With LEWA ecosmart a diaphragm metering pump for intermediate requirements has been delevoped: This series offers the best price-performance ratio in this class (80 bar, 120°C, 300 l/h) and meters, thanks to the proven variable eccentric drive, reliably, reproducibly and precisely. Different stroke frequencies of the drives allow adaptation to diverse fluids and process requirements.

The hermetically tight diaphragm pump also convinces with its dimensions: No other metering pump in this performance range is more compact.

Product benefits of LEWA ecosmart:

• Top operational safety and metering precision
• Compact design
• Standard drives according to IEC and NEMA
• Simple installation and start-up
• Sandwich design with diaphragm monitoring
• Suction pressure down to 0.1 bar

Typical fields of application include:

• Water treatment in power plants
• Metering of additives in industrial water processing
• pH adjustment
• Dosing of solvents in the chemical industry
• Feeding of corrosion inhibitors
• Dosing of colorants and flavors in the food industry
• Additive metering in the plastics industry
• Injection of chemicals in the oil & gas industry

The design is based on LEWA’s well-known and solid technology – using e.g. the PTFE sandwich diaphragm with diaphragm monitoring, the patented diaphragm protection system (DPS) and optimized check valves. LEWA ecosmart also has no problems complying with the rigid safety standards of API 675.

The sandwich diaphragm design with diaphragm monitoring ensures high availability. This technology reliably reports any damaged diaphragm. Yet the pump remains leakage-tight, and operations can continue for a certain time. An individually adjustable pressure relief valve prevents potential overload situations of the pump.

Since some weeks a new option with a PVC pump head is also available. That means the ecosmart can even be used in applications that require good resistance against highly aggressive chemicals – including industrial water treatment systems, for example when sodium hypochloride is in use. The PVC pump head can be used at pressures up to 12 bar (stainless steel: up to 80 bar) and at temperatures of up to 60 °C (stainless steel: up to 120 °C).

Regardless of the implementation of the pump head, the metering quantity in all ecosmart metering pumps can either be adjusted manually using handwheel on the gear box (manual stroke adjustment, changing the stroke length of the piston), electrically with an electric stroke actuator or by speed control of the drive motor using a VFD.
