Diaphragm pump: application and characteristics
Diaphragm pumps are designed for pumpingBoth pure liquids having low viscosity, and abrasive solutions having an average consistency. Devices are able to move large particles without damaging the equipment.
The diaphragm pump is able to work withdifferent volumes of liquid. It can pump from one to a thousand liters of fluid per minute. The pressure can be adjusted and reaches 8 bar. There are models that have the ability to self-pumping.
They allow you to raise water to a height of 8 meters,working dry, without risk of damage. When the outlet pipe is closed, the diaphragm pump stops its operation and starts again when it is opened. This design and operation principle allow to avoid the installation of a by-pass or safety valve.
Pumps are made from various structuralmaterials. Thus, metal devices are made of cast iron, aluminum, stainless steel and Hastelloy-alloy. Non-metallic devices are made of polypropylene and acetal.
The greatest demand is for a diaphragm pumpfirm ARO. The product range of this manufacturer is very diverse. For general industrial use, compact devices with sizes from 1/4 to 3/4 inches are suitable. These devices have high performance and small dimensions. Such a diaphragm pump can pump 56 liters of fluid per minute.
Among the professionals in the chemical fieldpopular are 1-3-inch devices with a capacity of 1040 liters per minute. The devices are characterized by excellent performance characteristics and reasonable cost.
The diaphragm vacuum pump is differentefficiency, availability of options, reliability, environmental friendliness. Maximum productivity is achieved by the design of the device, which allows a large flow of liquid with minimal pulsation and air consumption.
Presence of a manifold with multiple locationsand the number of inputs and outputs in combination with a variety of options allows you to use devices in various areas. Reliable, reliable operation during the entire service life is ensured by the presence of an oil-free primary or pilot differential valve. Bolted construction allows to achieve maximum chemical stability and prevent leakage.
Modular device, reduced amountstructural parts and easy application of repair kits minimize the cost and repair time. The presence of the main air valve makes it possible to prevent the device from stopping, even at low pressure of the outside air.
