Claw vacuum pumps like roots vacuum pumps and screw vacuum pumps are non contact dry vacuum pumps.
Dry claw vacuum pump working principle.
These claws are only separated from one another by a minimum gap and do not touch.
The main components of dry claw vacuum pump and compressor are two claws which turn in opposite directions in a housing.
They are specified for fine chemicals and pharmaceutical cgmp plants in order to avoid a product contamination.
The c series dry claw vacuum pumps and claw air compressors of elmo rietschle generate contact free vacuum or compressed air efficiently and economically.
A synchronisation gearbox ensures exact synchronisation of the claw rotors.
Mink mv series vacuum pumps belong to the busch product family of proven mink dry claw vacuum pumps.
The two claw shaped rotors do not touch during operation which eliminates wear and thus decreasing service needs overall ownership cost.
They are multistage roots systems or screw or claw compressors.
Dry claw pumps are ideal for applications that require low maintenance and increased process compatibility.
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.
Dry claw vacuum pumps and compressors principle of operation.
Claw vacuum pumps are driven by a directly flange mounted asynchronous motor with an efficiency class ie2.
With claw vacuum pumps two claw shaped rotors turn in opposite direction.
Claw pump dry positive displacement the claw pump fig.
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.
Next let the dry screw vacuum pump manufacturer evp continue to describe the principle and characteristics of claw vacuum pump.
Claw vacuum pumps are ideally suited to use with frequency controlled drives.
Claw vacuum pumps types.
Claw vacuum pump is not only a kind of volumetric vacuum pump but also a dry vacuum pump.
Quiet efficient and compact.
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.
They have been specially d.
This is possible because of the principle of internal compression in the rotary claw design.
Dry claw vacuum pump.
The gas is pre compressed within the compressing chamber and is then discharged.
