DBY series stainless steel 304 electric diaphragm pump anti-corrosion, acid alkali resistance didphragm pump
Brief introduction
DBY fluoroplastic electric diaphragm pump is one of the many fluoroplastic water pumps.Fluorine-plastic electric diaphragm pump is a water pump with very strong corrosion resistance. The over-flow part of the pump body is made of high quality polyvinylidene fluoride material. PVDF has good chemical stability, excellent chemical corrosion resistance and heat resistance. It can be applied to any strong acid, strong alkali and all kinds of organic solvent except molten alkali salt.
The source power of the DBY fluoroplastic electric diaphragm pump is given by Siemens bede motor, which drives the diaphragm plate on the connecting rod shaft of both sides of the pump body to reciprocate to and fro through the reducer. The left and right pump cavities are equipped with four single ball valves, and the left and right motion of diaphragm plate leads to regular changes in the volume of pump cavities. Force the four single ball valves to open and close alternately to draw and discharge the fluid.

Material selection of pump body
Common liquid (ph6-8, weak acid-base, such as rainwater,common sewage, oil, etc.) : please use aluminum alloy, cast steel diaphragm pump.
Common alkalinity, high acidity (PH value 3-8), such as low concentration of sulfuric acid or nitric acid, temperature 0-60
degrees: please choose polypropylene electric diaphragm pump
Strong alkalinity or strong acidity (PH value 2-9), such as high concentration of sulfuric acid, nitric acid, hydrochloric acid, and so on, low pump outlet pressure: please choose fluorine plastic PVDF electric diaphragm pump
Ordinary acidic, alkaline relatively strong (PH value 5-11), high pressure, high temperature: please use stainless steel electric diaphragm pump
Strong acid, alkali, solvent, or high hygiene requirements, high working pressure: please choose the steel-lined teflon electric diaphragm pump
Note: there is no difference between good and bad pump materials. It is important to select the correct pump materials according to the liquid pumped. The above is the reference data for the selection of conventional media. In the actual selection, please provide the specific chemical components of the media to our company's customer service, so as to select the pump material more accurately.
| Diaphragm material selection | |
| NBR | Carbon disulfide, carbon tetrachloride, oil: oil, diesel, and other temperatures 0-80 |
| Santoprene | Paint, weak acid, alkali and other special weak corrosive liquid, temperature 0-100 |
| PU,EPDM | Mortar, sludge, and so on, wear greater normal temperature liquid: ethylene propylene |
| Teflon | Food, medicine and other industries, strong acid, strong alkali or high temperature |
