sulfuric acid pump, low pressure electric diaphragm pump, double diaphragm PTFE
Ⅰ. General description
The Electric Diaphragm Pump is mechanically driven by electric power as opposed to air operated. For applications where there is an Explosive Atmosphere, we have EXD explosive proof motor. They are available in a single diaphragm configuration, and also a double diaphragm configuration. An electric diaphragm pump DB series, is a positive displacement pump which operates with a flexible diaphragm, and integrated check valves. The diaphragm is moved inward & outward toward the pump body which works in conjunction with the check valves and draws in and expels the fluid out the pump casing.
How to select an electric diaphragm pump:
1st step: the liquid or fluid type to be checked for the chemical compatibility characteristics
2nd step: max flow range and pressure head
3rd step: max self priming height if it's needed
4th step: max particle diameter if it has particle
Ⅱ. Work Principle
The two symmetrical working chamber, each is 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 shafter 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.
Ⅲ. Main Applications
1. Various toxic, flammable and volatile liquids;
2. 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.
