57 Abstract AB [EN] Diaphragm pump, esp. for use in laboratories to pump radioactive, toxic, or otherwise contaminated liquids with a high metering accuracy, consists of a flexible piece of tubing, made of silicone rubber, rubber or other elastomers, with a suction valve at the bottom and a delivery valve at the top. This hose is mounted central in a plastic tube, pref. made of PVC, polyethylene or polypropylene, with a supply pipe through which a pulsating compressed air flow is maintained. The pump can be produced at a cost such that it can be thrown away after a few uses and need not be cleaned.
