5-4 Bellows dosing pump

Bellows dosing pump

DZ/DS/DZN  pump is a kind of bellows dosing pump, or bellows metering pump.
SIKOPUMP is a leading bellows dosing pump supplier and manufacturer from China.
The DZ/DS/DZN  metering pump is CE certificated.

Feature 

• No leakage: For 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 about one meter for 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 polyacrylate that is anti-winding and special prescription it can withstand countless reciprocating motion;
• Anti-corrosion: Pump body is made from polyacrylate valve adopts special EPDM, FPM resisting various acid alkali and other corrosive liquids;
• High Liquids temperature: The maximum medicinal liquid temperature is 60 C degree.

Product Overview

DZ or DS or DZN Bellows metering pumps operate on a positive displacement principle. These bellows 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 dosing 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.
