Phosphate precipitation with LEWA diaphragm pumps in sewage treatment plants

LEWA pumps offer the following advantages for metering of media for phosphate precipitation in water treatment:

• Exact metering of the precipitant (iron(III) chloride)
• Absolutely reliable starting of the pump from every operating state; no positioning of the diaphragm required
• The hermetic seal of the pump prevents the extremely aggressive precipitant from escaping
• Patented sandwich diaphragm with DPS (Diaphragm Protection System) and diaphragm monitoring
• Integrated pressure relief valve protects the pump against unacceptable overpressure situations (pressure surges/water hammers), which can cause damage to pumps or lines.
• Lowest life cycle costs due to high energy efficiency, low maintenance costs and extremely long service life of the sandwich diaphragm
• Highest reliability and availability even after operating error or in extreme operating states (such as a closed pressure or suction line)
• Environmentally friendly thanks to high operating reliability and low power consumption
