A vane type pump having a rotor with slots through which vanes extend and engage the inside of a cylindrical casing to pump upon rotation of the rotor. The slots have a longitudinal groove on each inner side facing each other and elongated carbon sealing elements are positioned in the grooves to sealably engage the vane extending therebetween. A leaf spring is positioned behind one sealing element in compression and its amplitude of movement, as a result of the dimensions of all the components, is limited to 0.6 mm or less.
