PRODUCT OVERVIEW                                                                                 

    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.



   No leakage: There is no mechanical sealing position, no leakage exists.

   Precision of outlet: +/- 1.5% high precision can be achieved at the condition of clean water.

   Self-suction: Suction range is 1 meter at the condition of normal atmosphere, temperature and clean water.

   Allowed to dry rotation: For working chamber bag consists of bellows, dry rotation is allowed.

  Long service life: The chamber is made from polypropylene that is anti-winding and special prescription; it can withstand countless reciprocating motion.

   Anti-corrosion: Pump body is made from polypropylene; valve adopts special EPDM, FPM, resisting various acid, alkali and etc. corrosive liquids.
