Abstract: A fluid pump for pumping fluid in a sample separation device includes a pump body device, a piston arranged for conveying fluid in a reciprocable manner in the pump body device, a seal arranged fluid-sealingly in contact with and between the pump body device and the piston, and a supporting body, which is coupled to the seal for supporting the latter. The supporting body is arranged at the pump body device, thereby forming a bearing for the piston.
