Product Description:

DBY series electric operated diaphragm (EOD) pump    


Product Description of DBY series electric operated diaphragm (EOD) pump 

DBY electric diaphragm pump is a new type of pumps, in recent years, because the diaphragm material made breakthrough progress, the more and more industrialized countries have adopted this type of pump, replacing part of centrifugal pump, screw pump, used in petrochemical industry, ceramic, metallurgy and other industries, DBY electric diaphragm pump suitable for low pressure, namely outlet pressure or less 3 KGF/cm2 occasions. DBY electric diaphragm pump is the factory production of a new type of conveying machinery, the motor through the reducer reduction drive, for all kinds of corrosive liquid, with grain fluid, high viscosity, volatile, flammable and poisonous liquid, all can with suction light suction do.

DBY electric diaphragm pump note: DBY electric diaphragm pump work first open the outlet valve, in the work are prohibited during the outlet valve closed.

Diaphragm materials: neoprene, fluoride rubber, Buna-N rubber and Teflon.
Casing materials: Cast Iron, SS304, SS316, Aluminum, PP, PP lining, PVDF, NBR lining


Usage of DBY series electric operated diaphragm (EOD) pump

All kinds of highly toxic, flammable, volatile liquid.

All kinds of strong acid, strong alkali, strong corrosive liquid.

Can transport 150 ℃ high temperature medium.

As a front-end send pressure device of all kinds of filter press.

Hot water recycling and circulation.

Oil tank truck, oil depot, oil loading and unloading.

Pump suction pickles, jam, mashed potatoes, chocolate, etc.

Pump suction paints, rubber, paint adhesive.

All kinds of porcelain glaze slurry, cement grout, mortar, and mud.

All kinds of rubber paste emulsion, organic solvent, and filler.

Pump for the tanker barge sewage and sit in a clearance from storehouse.

Hops and baking powder slurry, syrup, molasses.

Pump suction sewage in mines, tunnels, tunnels, sewers and sediment.

To transfer all kinds of special medium


Main features of DBY series electric operated diaphragm (EOD) pump

1, DBY electric diaphragm pump does not need to irrigation water diversion, automatic capacity of 7 meters above.
2, through the performance is good, diameter in 10 mm the following particle, mud, etc. Can easily through the.
3, due to the diaphragm will be transported medium and transmission machinery a separate, so medium never to external leakage. And the pump itself without shaft seal, the service life is prolonged greatly. According to the different medium, the diaphragm is divided into chloroprene rubber, fluorine rubber, polybutadience rubber, etc, can satisfy the requirements of different users.
4, pump body medium flows through part, can according to user requirements, divided into cast iron, stainless steel, rubber lining, the motor can be divided into ordinary type and explosion-proof type two kinds.




Q: Are CNBM pumps available in DIY stores?

A: Yes, currently, we’re available for DIY stores all over the world.

Q: Where do I have to send pumps for service?

A: You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China.

Q: Are your pumps acid-proofed?

A: To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid.

Q: Can your pumps mount Eff.1 motors

A: Currently, only on request though this will shortly be a CNBM standard.

Q: Are your pumps protected against dry running?

A: No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

Q:How much pressure does the inverter plasma cutter need to pump the 150psi?
Inverter plasma cutting machine requires 0.7MPa air pressure is enough. So as to start the cutting machine running properly and blow the metal liquid in the cutting hole in time.
Q:380V air compressor (air pump) connected to the pressure switch and AC contactor, how to connect the two thin wire?
Isn't the circuit diagram in place? The circuit design is differentIf the switch is normally closed, the series connection in the circuit may not startIf it is open parallel, the circuit may not affect the use of the circuit, regardless of which does not connect, will lose protection
Q:Is the screw air compressor more energy efficient than the air pump?
Screw air compressor, in fact, that is what you call the air pump, air compressor is now called, before people call it the air pump! The screw opportunity is much more energy efficient than the piston machine! Less supplies!
Q:What is the air pump for the loader?
In front of the oil inlet, that is the air pump.
Q:General pump can be used in the model airbrush on?
Recommended with gas tank, so that spraying will continue to be uniform. It is not recommended to use this kind of car to fill the air source.. Beijing Yihai model.
Q:What is the overheating of the printing press air pump?
What kind of model, if it is oil cooling, it may be the oil rotor is not good,
Q:Centrifugal fan can use as a pump? It can vacuum?
Yes, but it doesn't work. Vacuum pumps are generally used with liquid ring pumps and Roots pumps, and this effect can reach about 200-400Pa of the vacuum. If the vacuum requirement is higher, then there are other ways, including chemical methods.
Q:An air pump is not switched on and the voltage is normal
Do not only measure the voltage, such as lines too long or there is a virtual place, the voltage is not enough, the starting current increases, the line loss increases, the voltage of the pump is not enough. You can measure the voltage when you start the pump. If the voltage is not a problem, use the meter to measure the pressure relay, that is, whether the voltage control is normal or not. If the voltage control is normal, you should see if the motor coil is burned. In addition, the single-phase pump should pay attention to the capacitor, three-phase should pay attention to contactor is normal.
Q:The car isn't cold enough. Is it related to the air pump?
Is the air conditioning pump stuck? If you have not repaired the air-conditioning system, it is the quality problem. Not enough lubrication, excessive refrigerant and improper filling, more than the working speed, will cause compressor damage. If you have a problem, turn the axle end by hand
Q:Is the vacuum compression bag pump universal? Can my vacuum cleaner smoke?
There is a need not hand pressure pump compression bag now, you can search on Taobao, special favors or shajfw, you can find.
