A pump mechanism (100) is disclosed for mounting on a wheel (20) to keep a pneumatic tire (10) from becoming underinflated. The pump mechanism (100) comprises a frame (210, 230) having a first chamber (225) and a pump chamber (295); and a strike plate (220) positioned in the first chamber (225) and being connected to a plunger plate (240), the plunger plate (240) having a nose (242) for engagement with a diaphragm (280) mounted in the pump chamber (295). The pump chamber (295) is in fluid communication with a pump inlet (291) and a pump outlet (293). An actuation of the strike plate (220) in the first chamber (225) causes engagement of the nose (242) with the diaphragm (280).
