Abstract (en)
The invention relates to a method for manufacturing and assembling a pump (1), the method comprising the steps of providing a housing (2), providing a rotor (3) with a rotor axis (31) and determining an optimal distance (g_opt) between the housing and the rotor (3). The next step comprises varying the distance between the housing (2) and the rotor axis (31) in a tangency direction (d), so that the distance between the rotor (3) and the housing (2) is substantially equal to the optimal distance (g_opt). Finally, the last step comprises affixing the relative position between the housing (2) and the rotor axis (3).
