1428221-1, or better known as the electrochemical diaphragm pumps (EDP), is a type of diaphragm pump powered by electricity. This pump is considered to be a non-siphoning design, which is ideal for use in applications that require a low-pressure and low-flow rate. As the pressure in the pump increases, the flow rate also increases; when it reaches its maximum pressure and flow rate, it will automatically shut off.

Application Field

The 1428221-1 is used in a wide range of applications including manufacturing, automotive, chemical, and medical. The majority of applications require low pressures, so this type of pump is ideal. Additionally, they can be used to transfer and blend liquids, aerate liquids, move gases and vapors, mix paints, and pump light oils and lubricants. The pump can also be used to control pressure within a system, as well as filter, cool, and mix liquids.

Working Principle

The working principle of the 1428221-1 is simple and straightforward. An electric motor rotates an “off-centre” cam, which is connected to the diaphragm. As the cam moves, the diaphragm is pushed and pulled, creating a pumping action. The action of the diaphragm pushing and pulling on the liquid creates a vacuum, which draws the liquid into the inlet and then pushes it out of the outlet.

The 1428221-1 uses a non-siphoning type of diaphragm, which prevents the liquid from draining back into the inlet once the pumping action has been completed. This makes it ideal for applications that require a low-pressure and low-flow rate, as the non-siphoning diaphragm cuts down on the loss of liquid and helps keep the pressure constant.

The 1428221-1 also uses a “weep” valve, which is a safety measure that allows any excess pressure to be released from the system. The valve opens when the pressure reaches a certain level and then closes again when the pressure has been released. This helps keep the system from becoming over-pressurized and helps prevent any damage due to excessive pressure.

Overall, the 1428221-1 is a useful and versatile pump. Its non-siphoning and “weep” valve features make it ideal for applications that require low pressure and low flow. It can be used to transfer and blend liquids, aerate liquids, move gases and vapors, mix paints, and pump light oils and lubricants.
