Bellows Metering Pump

DZ/DS/DZR Bellows metering pumps operate on a positive displacement principle. These metering dosing pumps are designed to displace both corrosive and non-corrosive fluids. Accurate to ± 0.5% from stroke to stroke, when pump is set 50% to 100% of full stroke. Available with either EPDM or FKM elastomers, the self-priming and corrosion resistant features help provide the reliable, continuous duty throughout a variety of chemical dosing applications.
These Bellows Metering Pumps have a compact design saves space, allowing manufacturers to reduce the overall size, weight and cost of their finished products. Small dimensions also permit them to fit into extremely tight areas.
A high-efficiency motor drives an adjustable cam which operated the bellows. This simple mechanism provides virtually silent, accurate operation with no maintenance required.
