Abstract:
A device for pumping fluid, comprising:a hydraulic tank; a drive mechanism; and a hydraulic pump with an external gear pump mechanism coupled to said drive mechanism, said gear pump mechanism being housed in an integral coupling piece in a form of an independent base plate with a first and second sides connected to said hydraulic tank and said drive mechanism, said first and second sides having first and second flange elements, respectively, with substantially similar external dimensions, said flange elements having an external circumferential sides with radial recesses receiving seals overlapped by a free end on at least one of said hydraulic tank and said drive mechanism; whereby, differently sized hydraulic tanks and different types of drive mechanisms can be interchangeably coupled to said coupling piece in a manner of a building block system with said hydraulic tank, said drive mechanism and said hydraulic pump being three separable and independent components of the system, and with said hydraulic tank and said drive mechanisms being on one of said first side and said first and second sides, respectively.
