Demanding conditions of water cooling tower applications are served by Series 500 hydraulic metering
Models feature a Variable Oil By-pass stroke adjustment. This allows better valve performance compared to variable-linkage designs. Valve checks have extra time to seat, even in heavy liquids, since they are idle during bypass portion of suction and discharge strokes. These pumps also feature EZE-CLEAN valves. Their cartridges can be removed for cleaning without disturbing piping to the pump. Four automatic Series 500 control options are available: electric stroke control, pneumatic stroke control, variable speed control, and sodium hypochlorite gas bleed. Full metering pumps data are free.
