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
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
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
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
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.
