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.
