KD Series Diaphragm Metering Pump
The metering pump is a kind of special volume pump which can satisfy all kinds of strict technological process requirements. The flow rate can be steplessly adjusted in the range of 0-100%. It is used to transport liquids (especially corrosive liquids).
KD diaphragm series metering pumps are mechanical diaphragm metering pumps driven by motors. They are suitable for accurate metering of fluids in bottom pressure situations. There are many kinds of pump heads for precision metering pumps. The diaphragm of dosing metering pumps is made of multi-layer composite PTFE material. Precision metering pumps are widely used in sewage treatment, food additives and transportation of various special media because of their high metering accuracy, stability and high requirements.
Dosing metering pump operates safely and mechanically drives diaphragm. The pump has good sealing performance, no leakage, simple and safe assembly and maintenance. The pump can transmit high viscosity medium, corrosive liquid and dangerous chemicals. The pump flow regulation can adjust stroke length or motor frequency. The diaphragm is made of multi-layer composite structure. The first layer of super-tough Teflon acid-resistant film, the second layer of EPDM elastomer, the third layer of 3.0 mm SUS304 supporting iron core, the fourth layer of reinforced nylon fiber patch, and the fifth layer of EPDM elastomer fully encapsulated can effectively put forward the applicable life of the rising diaphragm.
