An advanced design of single or double diaphragms uniformly forced through grinding, making diaphragms more durable;

Double PTFE diaphragms show excellent corrosion resistance and leakage prevention;

The diaphragm status monitoring system can send out signals when one diaphragm ruptures, the pump can continue working till diaphragm replacement or it can be stopped directly without any pollution to fluids;

An accurate design of eccentric mechanism, including cam and spring eccentric mechanism, and integrated sleeve adjustable eccentric transmission mechanism;

Static seal of diaphragm at hydraulic end replaces dynamic seal of plunger, ensuring no leakage during fluid transportation;

Diaphragm movement directly driven by the slide bar replaces cyclic reciprocation of diaphragm hydraulically driven, so the structure of a mechanical diaphragm pump is simpler and makes maintenance more convenient;

Depamu mechanical diaphragm pumps, in a patented design, ensure a stable flow output;

Whether a pump is shut down or running, stable flow outputs can be stepless adjusted via the fine-tuning knob;
Since there is no safe relief device, it is suggested to install a relief valve on the outlet pipeline of the pump.
