Abstract

The invention relates to a screw spindle pump arrangement having a low-pressure connection, a high-pressure connection, a drive spindle, and at least one idling spindle. A feed section of the idling spindles can be divided into two feeding segments that can be driven either in series or in parallel. A screw spindle pump arrangement is thereby created with little effort, wherein two operating modes can be selected without controls technology. Two tap connections that can be connected by a connecting line are provided in a center area of the feed section. The connecting line can be blocked and the low-pressure side tap connection can thereby be connected to the high-pressure connection, and the high-pressure side tap connection can be connected to the low-pressure connection. A series circuit (high pressure, low volume flow rate) is created by the open connecting line, corresponding to a screw spindle pump according to the prior art. With the connecting line blocked, and the simultaneous pressure medium flow paths indicated above, the screw spindle pump arrangement can be simply operated as a parallel circuit (low pressure, high volume flow).
