Dry claw vacuum pump working principle.

Claw vacuum pumps are driven by a directly flange mounted asynchronous motor with an efficiency class ie2. Dry claw vacuum pump. The c series dry claw vacuum pumps and claw air compressors of elmo rietschle generate contact free vacuum or compressed air efficiently and economically. These claws are only separated from one another by a minimum gap and do not touch.

Claw vacuum pump is not only a kind of volumetric vacuum pump but also a dry vacuum pump. Dry claw vacuum pumps are advantageous in that there is no threat of contamination to the application as there isn t any lubrication in the main pumping chamber. Claw pump dry positive displacement the claw pump fig. 8 features two counter rotating claws and operates similarly to the roots pump except that the gas is transferred axially rather than top to bottom.

A synchronisation gearbox ensures exact synchronisation of the claw rotors. This is possible because of the principle of internal compression in the rotary claw design. Quiet efficient and compact. Claw vacuum pumps are ideally suited to use with frequency controlled drives.

Dry claw vacuum pumps and compressors principle of operation. Next let the dry screw vacuum pump manufacturer evp continue to describe the principle and characteristics of claw vacuum pump. Claw vacuum pumps are available in a wide range of sizes. They are suited for harsh environments such as wastewater treatment plants and are more efficient than some other types of pumps including the rotary vane pump.

They are specified for fine chemicals and pharmaceutical cgmp plants in order to avoid a product contamination. Dry claw pumps are ideal for applications that require low maintenance and increased process compatibility. With claw vacuum pumps two claw shaped rotors turn in opposite direction. Claw vacuum pumps like roots vacuum pumps and screw vacuum pumps are non contact dry vacuum pumps.

The gas is pre compressed within the compressing chamber and is then discharged. The two claw shaped rotors do not touch during operation which eliminates wear and thus decreasing service needs overall ownership cost. Claw vacuum pumps types. The main components of dry claw vacuum pump and compressor are two claws which turn in opposite directions in a housing.

It is frequently used in combination with a roots pump which is a roots claw primary pump combination in which there are a series of.
