Digital metering pump
Walchem offers the EK Series Metering Pumps with IP67construction. The waterproof solenoid-metering pump is designed for use in harsh environments. The pumps offer capacities up to 6.7 gph and a maximum pressure of 150 PSI. At 360 strokes per minute, the pumps provides an 1800:1 turndown ratio and will reduce the slug feeding found in most competitive pumps. They are perfect for indoor and outdoor applications where the pumps are frequently washed down.

Peristaltic pump
Watson-Marlow Bredel offers the 520 Series peristaltic pump for sodium hypochlorite handling. The combination of tube elements and pumphead design allows the series to be used in the accurate metering, dosing and transferring of sodium hypochlorite. Entrained gas, often generated by the hypo, is pumped with ease, eliminating the occurrence of vapor locking that prevents conventional pumps from functioning properly. The pumps contain fluids within the tube at all times and never allows the sodium hypochlorite to come into contact with the pump mechanism.
