Hydra-Cell Metering Solutions S Series electronic/solenoid diaphragm metering pumps are practical and efficient pumps for chemical injection. SM models are low in cost and easy to operate, featuring a simple hand-operated speed stroke dial. Each pump runs at a maximum of 300 strokes per minute and a minimum of 15 strokes per minute. Discharge volume can be set up to the maximum flow capacity in 0.1 ml/m units.

A variety of materials of construction, including liquid ends in PVC, PVDF, Acrylic (to handle outgassing fluids) and Stainless Steel, are available to meet a wide range of applications. A double-ball check valve ensures metering accuracy and reduces the possibility of water hammer. An anti-siphon check valve prevents clogging at the injection point and also aids in priming.

Other safety features include a foot valve that prevent backflow into chemical injection systems and (on select models) an external relief valve that automatically releases excess pressure that builds up inside the discharge side pipes due to clogging or if the discharge valve is closed.

Available with flow rates of 28 ml/min (high-pressure models) as well as 30, 60 & 100 ml/min. Optional solution tanks in three sizes (30L, 50L, 120L) are easy to install and combine the pump with a tank unit to offer large capacity in a space-saving design.
