Abstract

A blocking slide (38) for a pump comprises:a rotor contact area (48) designed to rest against a wave-shaped rotor collar of the pump, wherein the rotor contact area (48) comprises:lateral rotor contact surfaces (50) which are designed to rest in each case against side surfaces of the rotor collar, andan upper rotor contact surface (52) which is designed to rest against a radially outward-facing shell surface of the rotor collar,wherein the lateral rotor contact surfaces (50) are each implemented as conically rounded surfaces, wherein a first radius of curvature (R₁) in a lower region of the lateral rotor contact surfaces (50), which is remote from the upper rotor contact surface (52), is smaller than a second radius of curvature (R₂) in an upper region of the lateral rotor contact surfaces (50), which is adjacent to the upper rotor contact surface (52).
