A rotary claw vacuum pump is a dry vacuum pump that doesn’t use lubricants in the vacuum chamber, and hence the gas is not contaminated. It remains free from oil sentiments, eliminating the possibility of environmental pollution. The pump has two claw-shaped rotors that turn in opposite directions within the chamber. The shape of these claws causes it to suck gas in, after which it is compressed and discharged. The claws operate in such a way that they don’t come into contact with each other or with the cylinder in which they rotate. The pump has tight clearances between the claw rotors and the housing, optimizing the internal seal to guarantee consistant pumping speed. The pump also has a synchronization gearbox that ensures that the operation of the claw rotors is well synchronized.
Rotary claw vacuum pump systems from GlobalVac are driven by a flange mounted asynchronous motor, powered with a high level of efficiency. The technology invoked ensures that they adapt to sudden changes in configuration and air feed. The machines are ideal for frequency controlled drives and are available in a wide range of sizes.
Over the last few decades, developments in rotary claw vacuum pump manufacturing have consistently reduced the weaknesses experienced with older versions. There are variants for special applications such as high stream contents, increased oxygen contents, gas explosion protection, and dust resistance.
GlobalVac develops sophisticated vacuum pump systems for both small scale and industrial applications. Our latest efficiency enhancements come with completely oil-free operation and high pumping speeds. Our technology permits controllability and reduces energy consumption while increasing performance. The pumps are contact-free and work with almost no maintenance.
