Dry Claw Vacuum Pump Working Principle

Claw vacuum pump is not only a kind of volumetric vacuum pump but also a dry vacuum pump.

Dry claw vacuum pump working principle.

A synchronisation gearbox ensures exact synchronisation of the claw rotors. The c series dry claw vacuum pumps and claw air compressors of elmo rietschle generate contact free vacuum or compressed air efficiently and economically. Claw vacuum pumps types. Claw vacuum pumps are available in a wide range of sizes.

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. Quiet efficient and compact. 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. 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.

They are specified for fine chemicals and pharmaceutical cgmp plants in order to avoid a product contamination. Next let the dry screw vacuum pump manufacturer evp continue to describe the principle and characteristics of claw vacuum pump. They have been specially d. Dry claw pumps are ideal for applications that require low maintenance and increased process compatibility.

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 vacuum pumps are driven by a directly flange mounted asynchronous motor with an efficiency class ie2. The main components of dry claw vacuum pump and compressor are two claws which turn in opposite directions in a housing. This is possible because of the principle of internal compression in the rotary claw design.

With claw vacuum pumps two claw shaped rotors turn in opposite direction. These claws are only separated from one another by a minimum gap and do not touch. They are multistage roots systems or screw or claw compressors. Mink mv series vacuum pumps belong to the busch product family of proven mink dry claw vacuum pumps.

Dry claw vacuum pump. Dry vacuum pumps have been developed for the semiconductor industry in the 80 s and introduced in chemical and pharmaceutical process industries in the early 90 s. The two claw shaped rotors do not touch during operation which eliminates wear and thus decreasing service needs overall ownership cost. 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.
