Seal without leakage: Liquid is completely isolated by the diaphragm, so diaphragm metering pump have 100% proof of leakage. It is very good for the viscous, poisonous, corrosive liquid handing.

Easy maintenance: There are only several parts of components of diaphragm dosing pump. It has the simple structure, so it needs easy maintenance. Usually only need to change Lub. Oil and diaphragm.

Diaphragm pump head material: Besides SS304 and SS316 material, the pump head can be PVC, PTFE and other material. So, this will help the pump to delivery a wide range of chemical liquid type.

Double diaphragm: Although the diaphragm metering dosing pump has a good seal, for safety, pump can be in double diaphragm type with an alarm system, it will stop the pump when one diaphragm breaks.
