Abstract: A roller-type pump for corrosive fluids such as detergents. The pump has a soft internal tube squeezed by rollers to provide the pumping action, and stiff kink-resistant outside conduits conveying fluid to and from the pump. Assembly of the pump's cover with its housing produces a fluid and air-tight connection between the tube and conduits. The pumping rollers are mounted on a spindle made of two identical parts which can be easily assembled and disassembled without tools or fasteners for cleaning, and installed in either direction for ease of maintenance and uniform wear. There are no metallic parts in the pump chamber, and the cover is transparent to allow observation and leak detection during operation.
