Vacuum Pump

Types of vacuum pumps

A vacuum pump is a device that pulls gas molecules out of a sealed volume and maintains a partial vacuum. Its job is to create a relative vacuum within its capabilities. Several types of vacuum pumps are available, including scroll and rotary piston models. Each has its own characteristics and uses. To learn more, read this article.

Screw Pump

Screw vacuum pumps use a mechanical screw to move an air or gas chamber to the axial housing wall. The movement of the chamber reduces the volume of gas, which is pre-compressed before being expelled through the pressure connection. These pumps can be single-pitch models or variable-pitch models. Variable pitch models feature variable pitch rotors that help distribute heat loads evenly across the rotor. Some models also include a thermostatic control valve that shuts off the pump if the water temperature gets too high. Screw vacuum pumps are available in single-ended or double-ended designs. Single-ended and double-ended screw pumps provide up to 3.7 x 10-4 Torr and an ultimate vacuum of 900 m3/h (560 cfm), which is sufficient for many industrial processes. Progressive cavity pumps are particularly suitable for vapor compression applications. These pumps also have an internal rotor to minimize layer formation. Combined with air cooling, they are suitable for use in hazardous environments. In addition, the screw rotor design prevents the build-up of substances in the pump cavity that could react with high temperatures. These pumps are also easily removable for quick cleaning. Screw vacuum pumps are also designed for low cost and minimal maintenance. Agknx screw vacuum pumps are designed in Germany and are very reliable and economical. Pump performance depends on cooling system and temperature. The temperature of the water used should be kept within a certain range, otherwise the pump may overheat and fail. Screw vacuum pumps are often used in scientific experiments. They are standard main pumps in large storage rings, gravitational wave detectors, and space simulation chambers. One of the largest ultra-high vacuum chambers in the world is made of screw vacuum pumps. An example is the KATRIN experiment. There are two types of screw vacuum pumps: oil-sealed and dry. Oil-sealed screw pumps use oil as a sealant and coolant. They are suitable for demanding vacuum applications such as woodworking and plastics processing. Dry screw pumps have an air-cooled chamber, and they can achieve higher vacuum levels than oil-sealed pumps.

Rotary Piston Vacuum Pumps

Rotary Piston Vacuum Pumps provide the rugged performance essential for applications requiring vacuum. They can deliver flow rates up to 1280 acfm and reach deep vacuum levels up to 0.0004 Torr.

They also offer several advantages over other vacuum pumps, including low operating costs and environmental sustainability. Scroll vacuum pumps do not require oil, which is a big advantage in terms of cost. Scroll vacuum pumps are also quieter. Scroll vacuum pumps are designed for low, medium, and high vacuum systems. They create a high vacuum and cannot tolerate particles. Although they are relatively small, they are ideal for vacuum laboratory applications and are also suitable for dry vacuum pumping. They can be combined with chemically resistant PTFE components, making them more suitable for chemical applications. Scroll vacuum pumps feature a unique design that makes them very versatile and efficient. The pump has two helical structures, one is fixed and the other is rotating, which can effectively pump gas and liquid. When the rotor begins to move, the gas is compressed slightly and then flows through the system to the exhaust port. Scroll vacuum pumps are efficient, oil-free and compact. Known for their high tolerance to the atmosphere, they feature sensorless INFORM(r) control to minimize noise and vibration. These vacuum pumps are ideal for low to medium flow applications including analytical equipment, freeze dryers, vacuum coaters and mass spectrometers. The most important advantage of a scroll vacuum pump is its reliability. They can be used for three years or more without problems and are easy to maintain. With proper maintenance, they can reduce repair costs.

Diaphragm vacuum pumps

Diaphragm vacuum pumps are used in a variety of industrial processes. These pumps use an elastic diaphragm fixed around the outer diameter. They are efficient and can handle most types of liquids. They are commonly used for dewatering, filling and water removal. These pumps are easy to maintain. Diaphragm vacuum pumps are available in a variety of sizes and power outputs. Oil-free diaphragm vacuum pumps do not require oil, lubrication and cooling. These pumps are compatible with many types of laboratory equipment. Diaphragm vacuum pumps are equipped with dual voltage motors and DC drives for greater flexibility and durability. Diaphragm vacuum pumps can achieve higher vacuum levels than rotary vane pumps. They are more efficient than diaphragm pumps. They do not require oil and require less maintenance than their rotary vane counterparts. However, the diaphragms of these pumps may need to be replaced every few years. Diaphragm vacuum pumps are the most popular type of vacuum pump and can be used for a variety of applications. They can be used for everyday work and can be large enough to be used in a vacuum oven or rotary evaporator. Diaphragm vacuum pumps use pulsed motion to move air. They eliminate the need for oil and are highly chemical and steam resistant. They can handle a wide variety of samples, including high viscosity liquids. Diaphragm vacuum pumps are generally smaller than other types of vacuum pumps. Scroll pumps are made of metal and are generally recommended for solvent and water samples.
