It is the wear part inside the pump head.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow a peristaltic pump wears\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThere is no impeller and no seal in a peristaltic pump. A set of rollers pinches a flexible tube against the pump housing and pushes chemical along it. That means the tube absorbs all of the mechanical work, and it is meant to be replaced on a schedule rather than run until it fails.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy the timing matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDosing accuracy falls off before the tube visibly gives out. As the wall softens and takes a set, each revolution moves less liquid than the controller expects, so the system quietly under doses. Fitting a fresh tube brings the output back to where the controller is calculating from.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNaming\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis tube set appears under both the VidaPure and idaPure names in the manufacturer data.
