Abstract: A clamp for sanitary pumps includes a tensioning assembly mounted on a ring. The tensioning assembly includes an adjustment assembly that interfaces with first and second brackets disposed at first and second ends of the ring. The adjustment assembly includes a nut that interfaces with a rod at a threaded interface. A head is disposed at an end of the rod opposite the nut and interfaces with the second bracket. The nut and rod are coaxial and an orientation of a common adjustment axis can be changed by pivoting the adjustment assembly relative to the first bracket, to maintain concentricity between the nut and rod.

Abstract: Mechanical tubular diaphragm pump features are presented herein. Such a tubular pump can include a resilient tube having a lumen and a pair of upstream and downstream check valves located along the same fluid pathway as the lumen. The tubular pump further includes a motorized reciprocating unit and a depressor configured to be moved by the motorized reciprocating unit to cyclically depress and release the resilient tube. The resilient tube forces fluid within the lumen downstream past the downstream check valve as the resilient tube is depressed by the depressor, and further pulls upstream fluid past the upstream check valve and into the lumen as the resilient tube returns upon release by the depressor. Multiple resilient tubes may be used in the same pump. The tube(s), depressor, and valves may be attached to a housing that is modularly removable from the motorized reciprocating unit.
