Diaphragm pumps are designed for pumping both clean liquids with low viscosity and abrasive solutions having an average consistency. Devices are capable of moving large particles without damaging the equipment.
Pneumatic accessories can be used even in potentially explosive atmospheres due to the appropriate engine design.
The diaphragm pump is able to work with various volumes of liquid. It can pump from one to a thousand liters of fluid per minute. In this case, the pressure can be regulated and reach 8 bar. There are models with the ability to self-download.
They allow you to raise water to a height of 8 meters, working dry, without risk of damage. When closing the outlet pipe, the diaphragm pump stops its action and starts again when it is opened. This design and principle of operation make it possible to do without installing a bypass or safety valve.
Pumps are made of various structural materials. So, metal devices are made of cast iron, aluminum, stainless steel and hastelloy-alloy. Non-metallic devices are made of polypropylene and acetal.
Corrugated diaphragms are used in all devices, which allows to increase the working life and reduce the cost of technical periodic maintenance.
The ARO diaphragm pump is in greatest demand. The range of products from this manufacturer is very diverse. For general industrial use, compact devices ranging in size from 1/4 to 3/4 inch are suitable. These devices have high performance and small dimensions. Such a diaphragm pump can pump 56 liters of fluid per minute.
Among professionals in the chemical field, 1-3 inch devices with a capacity of 1040 liters per minute are popular. Devices are distinguished by excellent performance and reasonable cost.
The diaphragm vacuum pump is characterized by efficiency, availability of options, reliability, environmental friendliness. Maximum productivity is achieved thanks to the design of the device, which allows for a large fluid flow with minimal ripple and air consumption.
The presence of a collector with multiple locations and the number of inputs and outputs in combination with a variety of options allows the use of devices in various fields. Reliable, reliable operation over the entire life cycle is ensured by the presence of an oil-free main or pilot differential valve. The bolted construction allows maximum chemical resistance and prevents leakage.
The modular device, the reduced number of structural parts and the ease of use of repair kits minimize the cost and time of repair. The presence of the main air valve prevents the device from stopping even at low pressure from the outside air.
