Diaphragm type metering pump

Product Overview

Description

                                             Diaphragm type metering pump

 

product overview:

 

The main parts of the mechanical diaphragm metering pump are made of precision casting and NC machining.According to the design of the liquid end structure, the water pump can not leak during operation.The drive parts are strong and durable.

 

Due to its compact design, it is convenient to operate and operate.The flow rate can be adjusted simply by the flow control knob, and the installation and routine maintenance are convenient.

    

 Product features:

 

1.Safe operation, mechanical drive diaphragm.

2. Good sealing, no leakage, assembly and maintenance simple and safe.

3.It can transport high viscosity medium, corrosive liquid and dangerous chemicals.

4.Flow adjustment can adjust stroke length or motor frequency.

  The diaphragm is composed of multilayer composite structures,First layer super toughness Teflon acid resistant film,Second layer EPDM elastic rubber,  Third layer 3.0mm stainless steel 304 support iron core, The fourth layer is made of reinforced nylon fiber,  The fifth layer is made

1.of EPDM elastic rubber, which can effectively raise the service life of the diaphragm.

 

 

Widely used in petroleum, chemical, chemical, power, metallurgy, mining, shipbuilding, light industry, agriculture, national defense and other industries.

Metering pump principle:

The principle of this series of products is the mechanical diaphragm type metering pump driven by the motor through the turbine worm,It is suitable for measuring fluid in low voltage field.

Diaphragm type measuring pump replaces piston with flexible diaphragm,Driven by the driving mechanism, the diaphragm moves back and forth,Change the pump chamber volume,Suction and discharge the liquid under the action of the inlet and outlet valve of the pump.

Diaphragm metering pump according to the needs of various processes,The flow can be stepless adjusted in the range of 0-100%,Quantitative transport of corrosive and non corrosive liquids without solid particles,The pump head is equipped with a variety of over current materials (PPH, PTFE, PVC, PVDF, RPP, SS304, 316, 316L).

Diaphragm metering pump because the diaphragm can be used to bypass the flow of liquid and drive the complete separation of lubrication,Using high tech structural design,And the use of the latest PTFE and rubber composite diaphragm, corrosion resistance, greatly improved the service life of the diaphragm.
