Abstract
A pump that has a flexible liner located adjacent to a diaphragm. The liner provides structural support for the diaphragm. The flexible liner can slide relative to the diaphragm. This relative movement reduces the stiffness of the diaphragm/liner assembly. The diaphragm/liner assembly is therefore both flexible and strong. Additionally, the liner provides a thermal insulator for the diaphragm. The flexible liner may be constructed from a low friction material to lower the friction between the liner and a wobble plate of the pump. Lowering the friction reduces the heat generated within the pump. The structural reinforcement, thermal insulation and lower friction features of the liner increase the life of the diaphragm and the pump.
