IDEAL FOR ABRASIVE
AND HIGHLY VISCOUS MEDIA

Rotors for eccen­tric screw pumps 

Eccen­tric screw pumps belong to the pos­i­tive dis­place­ment pump fam­i­ly and are used where the tech­ni­cal tasks exceed the pos­si­bil­i­ties of pumps of con­ven­tion­al design. In the field of con­vey­ing tech­nol­o­gy, they are used for pump­ing abra­sive, high­ly vis­cous and cor­ro­sive media. This has con­tributed to a sig­nif­i­cant expan­sion of the range of avail­able con­vey­ing sys­tems. Eccen­tric screw pumps con­sist of a rotat­ing com­po­nent, the rotor, and the sta­tion­ary sta­tor locat­ed around it. The rotor rotates eccen­tri­cal­ly, as its axis of rota­tion does not cor­re­spond to the axis of sym­me­try of the sta­tor. The con­struc­tion of both com­po­nents form cham­bers through which the respec­tive medi­um is con­veyed by rota­tion in the pump via the suc­tion to the dis­charge side. Rotors con­sist main­ly of steel and have a spe­cial spi­ral geom­e­try as the rotat­ing cen­tre in the sta­tor. Dif­fer­ent mate­ri­als are used in the JÄGER Group in the man­u­fac­tur­ing process of rotors for eccen­tric screw pumps. 

Rotor pro­duc­tion

We man­u­fac­ture single‑, dou­ble- and mul­ti-start rotors for all pump­ing tasks – adapt­ed to the respec­tive media and require­ments. Togeth­er with our cus­tomers we devel­op inno­v­a­tive rotor geome­tries with spe­cial heads and cre­ate cal­cu­la­tions and designs based on the lat­est 3D soft­ware. 

In addi­tion to our stan­dard sizes, we also pro­duce larg­er com­po­nents up to a length of 8 metres for you. For rotors, we offer exten­sive coat­ing tech­niques such as hard chrome plat­ing and car­bide coat­ings (e.g. tung­sten car­bide, chrome car­bide) in order to guar­an­tee max­i­mum ser­vice life and min­i­mize wear even with the most dif­fi­cult pump­ing media in ever new areas of appli­ca­tion. 

New devel­op­ments for the con­vey­ing tech­nol­o­gy, the cre­ation of pro­to­types as well as all pro­cess­ing steps of the lat­er series pro­duc­tion can be car­ried out com­plete­ly inde­pen­dent­ly of exter­nal sup­pli­ers in our own com­pa­ny. Thus we offer the great­est pos­si­ble secu­ri­ty, also for your innovations!

The diverse fields of appli­ca­tion of our rotors 

Artemis rotors are often used in pumps at ele­vat­ed tem­per­a­tures. In order to ensure that the con­vey­ing sys­tem runs effi­cient­ly and smooth­ly, we adjust the rotor dimen­sions accord­ing to the expan­sion that occurs. As a spe­cial­ist in com­po­nents for con­vey­or tech­nol­o­gy, our rotors are used in the food indus­try, the chem­i­cal indus­try, the con­struc­tion indus­try and in the extrac­tion of crude oil, among others. 

Our qual­i­ty assurance 

To ensure our high qual­i­ty stan­dards, we use the lat­est 3D coor­di­nate mea­sur­ing tech­nol­o­gy. Under the premise of pre­ci­sion at the high­est lev­el, the pro­duc­tion facil­i­ties and machin­ery of the JÄGER Group are cer­ti­fied accord­ing to DIN EN ISO 9001:2000. 

In our devel­op­ment and pro­duc­tion process­es, we pay atten­tion to the per­fect coor­di­na­tion of sta­tor and rotor geome­tries to ensure opti­mum effi­cien­cy. We achieve this by using the lat­est 3D tech­nol­o­gy as well as sim­u­la­tions of the lat­er oper­at­ing behav­iour of the rotor.
