A cheek plate for a vane pump is provided which is made of an aluminum alloy. The cheek plate has a first or casing face which faces towards the casing of the pump when installed in the pump. A second or rotor face of the cheek plate faces the rotor when the cheek plate is installed in the pump. The cheek plate further includes a first radially outwardly located pressure control passage configuration, a second pressure control passage configuration located radially inwardly with respect to the first pressure control passage configuration. A first radially outwardly suction control passage configuration located diametrically opposite to the first pressure control passage configuration and a second suction control passage configuration located radially inwardly with respect to the first suction control passage configuration. The first and second pressure control passage configurations and the first and second suction control passage configurations extend between the casing face and the rotor face. At least the radially outwardly located pressure passage configuration includes at the rotor side a recess with connecting openings extending to the oppositely located casing face.
