Abstract:
1. A feed pump for supplying lubricant to at least one lubricating point, the feed pump comprising at least one driving module and at least one pump module, each of which modules is selected from a modular system that comprises at least first and second driving modules and the at least one pump module, wherein each of the driving and pump modules of the modular system comprises at least one connecting region, and wherein the connecting regions are configured in such a way that one of the first and second driving modules is capable of being exchanged for the other of the first and second driving modules, wherein the at least one pump module comprises a piston, wherein the first driving module comprises a rotary motion-linear motion conversion gear in contact with the piston of the at least one pump module when the first driving module is connected to the at least one pump module at respective connecting regions, and wherein the second driving module comprises a hydraulically and/or pneumatically driven piston arrangement for driving the piston of the at least one pump module when the second driving module is connected to the at least one pump module at respective connecting regions.
