Product description

GB series mechanical diaphragm metering pump is a branch product of metering pump. Its working principle is that diaphragm reciprocating movement forms a change in pump chamber volume, and through one-way valve control material flow direction, it plays a metering and conveying function. The diaphragm of the diaphragm metering pump usually has PVDF, PTFE and other materials, and improves the diaphragm strength through multi-layer composite. Diaphragm metering pump is a commonly used metering pump, and the metering accuracy is slightly lower than the plunger metering pump. Because the diaphragm is the main component of the hydraulic end, its sealing performance is better and can be completely leak-free. The diaphragm metering pump in Zhongcheng Pump Industry adopts aluminium base, which effectively reduces the weight of the whole pump and makes the copper turbine more durable.


Product features

The cast aluminum shell has high heat dissipation performance and light weight. It is suitable for all kinds of acid and alkali liquid medicine, and is non-toxic and tasteless.

GB series mechanical diaphragm metering pump adopts cam mechanism. As a whole, it has no leakage and can be placed on the medicine trough or pipeline.

The contact medium pump head is PVC, optional PTFE, and stainless steel material.

High cost performance, generally applicable to water treatment industry with low pressure requirements.

When the diaphragm metering pump runs or stops, it can also adjust the flow freely and output quantitatively.

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.mm SUS304 supporting iron core, the fourth layer of reinforced nylon fibers, and the fifth layer of EPDM elastomer fully encapsulated can effectively improve the service life of the diaphragm.
