Abstract
A bellows-type pump has a plastic bellows interiorly supported by interior pressure. The interior pressure is supplied by a fluid source which passes through a pressure regulator to control the amount of interior pressure exerted on the bellows. A fiber-optic leak detector can be inserted into the plastic bellows to detect the leakage of process fluid therein.
