DBY-25 Electric Diaphragm Pump, Aluminum Alloy

Product Overview：

The DBY electric diaphragm pump is a novel pump type manufactured by [Zhilong Pump Industry]. In recent years, owing to breakthroughs in diaphragm material technology, an increasing number of industrialised nations worldwide have adopted this pump design to partially replace centrifugal pumps and screw pumps in industries such as petrochemicals, ceramics, and metallurgy. Suitable for low-pressure applications (discharge pressure up to 3 kgf/cm²), it employs an electric motor driven through a reduction gearbox. This pump effectively handles various corrosive liquids, liquids containing particles, as well as high-viscosity, volatile, flammable, and highly toxic liquids, ensuring complete extraction.

Five material options: cast iron, aluminium alloy, stainless steel, engineering plastic PP, and fluorinated lining. Diaphragm pumps utilise diaphragms, sealing balls, and ball seats made from materials such as nitrile rubber, neoprene, polytetrafluoroethylene, and polyvinylidene fluoride F46, tailored to different liquid media to meet diverse customer requirements. Since their introduction, DBY electric diaphragm pumps have been adopted by numerous petroleum, chemical, electronics, ceramics, and textile enterprises worldwide. Installed in diverse specialised settings, they reliably handle media inaccessible to conventional pumps, consistently delivering satisfactory performance.

Product Features：

Can be used in the case of bad air source, the Derlin material in the direction of the sliding block is strong and durable, not easy to damageGas flow,from 1/2 "to 3" pump gas path without obstacles,ensureflexible reversing.100% external maintenance type reversing valve

Compared with other double diaphragm pumps, the moving parts are very few.

Reversing valve without lubrication.

Pilot operated directional valve has a very high mechanical life, can ensure the day-to-day operationA change valve suitable for a variety of specifications of the pump.

Product Installation Notes：

1,Electric disphragm pump is stritly prohvibited to installthe valve, such as the need to install the valve; to installthe safety valve in the outhet, theworking pressure shall not exceed 4 kg, so as to avoid loss.

2,should be in a timely manner, to maintain the normal operation of the lubrication system.

3,the pump in the use of the ambient temperature should be less than 40'C,the motor temperature shall not exceed'C

4, the transmission of the medium and its temperature should be in the range of pump material allowed.5S,for conveying a liquid crystalline medium forthe easy precipitation,should be cleaned after use drain pump inner product damage,so as not to pen

Product Application Examples：

Cable joints must strictly follow the attached diagram:

1,the tank bottom cleaning ped, despite the water pumping.can not guarantee the oil pumping net surface to rest at least 3-Smm thick oil leyer,In500om' tank,for example, the loss of 1-1,5St oll per time, for the oil tank witha low position,although the r emaining oiland water discharged into thesewage treatment field recovery,but volatile oil in the transport process mostly volatile,and the environment.

2,temporary pour tank,loading and unoading vehicdles and oil sampling,oil refining production scheduling process often to temporaril pour tanks,loading and oll tank in the sample test,. Or in order not to pollute the normal pipeline, the use of the temporary pipetline can be quicklyand easly to

complete the task.

3,oiltanker bottomoilrecovery.a 3000t of the oiltanker with s fixed screw pump unloding between the partitionplate to t leasthe r emaining 50t oil,if the larger displacement of the diaphragm pump, you can get a good effect.

4,Gas, hydrogen sulfide transport.the torch at the bottom of the refinery gas residue and sulfur water, need to concentrate on emissions and processing,

otherwise it will become acid corrosion equipment.

5,Ceramic industry: the pump suction glaze slurry and can be used to filter pressing.

6,wells,ditch out waterlogging, waste ollin the wel pipe, drain valves and maintenance, to exclude waterlogging and waste oll,Submersible pump can bepumped to waterlogging,but often these places are far away from the power source, very convenient The use of diaphragm pump can be usedcompressed gas as power, waste oil recovery.waterlogging drainage.

7,cleon the sewage treatmen tfield and sludge poo: pool sludge sewage treatmentfield, often ascumulates alarge amount of clay and sil, need cleaningdiaphragm pump suction is flexible and convenient,labor saving,time saving.

12,the pumpin the use of the ambient temperature should be less than 40 degrees,the motor temperature shall not exceed 75.

13,the transmission of the medium and its temperature should be in the range of pump material allowed.

14,for conveying a liquid crystalline medlum for the easy precipitation,should be cleaned sediments within the row net pump after use,so as to avoiddamage to open.
