Wanner Engineering Inc. - www.hydra-cell.com
Designed for chemical injection, Wanner Engineering Hydra-Cell Metering Solutions SM Series electronic solenoid metering pumps are suitable for a range of food and beverage applications. They feature a hand-operated dial with adjustments from 15 to 300 strokes per min., maximum discharge volumes from 28 to 100 mL/min. and maximum discharge pressure ratings from 58 to 217 psi (4 to 15 bar). A double-ball check valve helps reduce the possibility of water hammer, while an anti-siphon check valve prevents clogging at the injection point and aids in priming the pump. An optional integral relief valve releases abnormal pressure automatically if the pressure exceeds the pump’s capability. All models are equipped with a protective secondary diaphragm.
