Mechanical diaphragm metering pump DPMFWA/WAA

feature

Excellent dual diaphragm design, with a multi-layered diaphragm structure that has been rolled to ensure even force distribution and durability;

The double diaphragm made of PTFE material has excellent corrosion resistance and impermeability.

The diaphragm status monitoring system can output signals when the diaphragm is damaged, and can continue to work until the diaphragm is replaced or the pump is stopped directly, without polluting the measuring medium;

Accurate eccentric structure design, with cam and spring eccentric mechanisms and integral sleeve adjustable eccentric transmission mechanism;

The static seal of the hydraulic end diaphragm replaces the dynamic seal of the plunger, thus achieving no leakage of the conveying medium;

The sliding rod directly drives the diaphragm to move instead of using hydraulic pressure to drive the diaphragm to perform reciprocating periodic motion, making the structure of mechanical diaphragm pumps simpler and easier to maintain;

The patented mechanical diaphragm design ensures stable flow output.

Whether in shutdown or operation, smooth and stable output flow can be infinitely adjusted by adjusting the knob.

◆ There is no safety relief device, it is recommended to install a safety valve on the outlet pipeline of the pump.

Scope of application

Widely used in industries such as environmental protection, pharmaceuticals, papermaking, sewage treatment, urban water supply, and cement grinding aids.
