Series 500 and 600 hydraulically balanced metering pumps and Series 7000 mechanically actuated metering pumps are designed to serve the water and wastewater markets. Series 500 pumps utilize the company’s Variable Oil By-pass stroke adjustment, which allows better valve performance when compared to variable-linkage designs, according to the manufacturer. Series 7000 can handle viscosities in excess of 5000 cps, and capacity can be adjusted by a micrometer dial while the pump is running. The variable-speed drives allow greater turndown range or automatic capacity control.
