Product Details

DBY Series Electric -Operated Diaphragm Pump

★ Operating Temperature:-20oC ~ 120 oC

★ Flow Range :3.4gpm -67.4gpm

★Pump lift:4bar -7 bar

★ Product Overview:

DBY Series, the third electric diaphragm pump adopted the cycloidal reducer which is enable the

volume of left and right pump chamber, so as to suck in and exhaust liquids, is one new kind of

pumps, which has been employed in more and more industrialized countries over the world in

recent years because of the breakthrough development in its diaphragm materials, it displaces

some centrifugal pumps and screw pumps and is used in the fields of chemistry, ceramics,

metallurgy and so on.

★ Design Feature:

Each of two symmetrical working chamber are equipped with a piece of elastic diaphragm, which

is connected by a connecting rod that square groove is on the above. With the key, the motor

Shaft is connected to a piece of eccentric shaft connected with the bearing, which is working

with the above square groove. Connecting rod can be working, when the motor rotates.

When connecting rod shaft to the left movement, the left chamber being in compression state,

the liquid was squeezed out of the chamber, at the same time the right side of the chamber is on

expansion, so the external liquid can be inhaled into the chamber in the body; After connecting

rod movement to the right, the right chamber in compression state, the liquid is compressed to

outside, at the same time the left chamber on the expansion can the external fluid into the

chamber in the body, thus realize the motor drives the diaphragm work back and forth, the

medium's transfer function.

★ Pump Advantage :

1. Self-priming ability of more than 7 meter without irrigation water.

2. Good Performance, Particles below 10mm, slurry ,etc. Can effortlessly pass through .

3. Since the diaphragm is separated from the transmission medium and transmission machinery ,The media will not be leaked out. And the pump itself is unsealed ,which greatly extended service life. Depending on the medium ,the diaphragm can be divided into chloroprene rubber. Fluorine rubber, nitrile rubber ,etc.which meet different customers needs.

4. Medium flows through the pump part, according to customer requirements. Are divided into cast iron , stainless steel ,rubber lined . Motors can be divided into ordinary and explosion-proof.

★ Application Field :

1. It can transfer Various toxic, flammable and volatile liquids;

2. Deliver Various strongly acidic, strongly alkaline and strongly corrosive liquids;

3. Transmitting mediums with high temperature at 150;

4. Backing pressure feeder for various filter presses;

5. Employed for retrieving and circulation of heat water;

6. Loading and unloading of oil tankers, oil depots and oil goods.

7. Pumping of pickles, jams, mashed potato and chocolate etc.

8. Pumping of paint, gum and pigment adhesives;

9. Employed for various porcelain, glaze, cement, grout, mortar and slurry;

10. Employed for various rubber, latex, organic solvent, stuffing;

11. Employed for clearance of oil tanker barge to suck off inner sewage and residual oil.

12. Employed for hops, yeast thin grout, syrup and molasses;

13. Pumping of sewage and sediment in mine, adit, tunnel and sewer.

14. Suction and transmission of various special mediums.
