Bellow Dosing Pump for Sale

Corrosion resistant, multi-purpose pump

Manufactured using a combination of polypropylene and synthetic rubber, the pumps in this series can handle acids, alkalis, and various corrosive chemical solutions. Furthermore, capable of dry run operation and self-priming, these pumps can be used for multiple purposes as desired.

Leakage-free, safe structure

Since the pumps in this series are free of shaft seal, there is no trouble caused by liquid leakage. Also, the pump has its motor protected with a cover.

Superior durability

The specially designed bellows, molded as a single body, can ensure tens of millions of expansion and contraction cycles. Combined with its rugged drive mechanism, the pump provides superior durability.

Wide range of discharge capacity

The pump provides three types of flow rates by changing its bellows. Moreover, if the pump is a multi-head type, proportionate injection of several different liquids is also possible.

Features and Benefits Of flexible bellows for pumps

No leakage, for there is no mechanical sealing part, 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 PP with special prescription that could withstand millions of reciprocating motion; Anti-corrosion, metering pump body is made from PP and the valve is made from special prescription of FPM,EPDM that could resist various acid alkali and other corrosive liquids; The liquid temperature, the maximum pressure become half level when the temperature from 20°C to 50°C. if the temperature of liquid exceed 40°C, the corrosive rate would rise.

Purpose: Automatic washing for color film, expansion of photograph, X-ray film, microfilm, cine-film and others ; using on beverage vending machine; using on Mucus blending and ration of addition for food additive; Using on Etching, cleaning, and printing of electronic substrate printed circuits ;using on acid-base neutralization of water treatment and NGL input; Dosing of plating solution; Widely used in the quantitative input of various agents such as additive and other bleach.
