ABSTRACT:
The amount of wear on the vanes of a sliding vane rotary pump is determined by inserting a wear inspection dip stick into a wear inspection port providing in a housing of the sliding vane rotary pump. The wear dipstick includes one or more mark providing an indication of the amount of wear on the vanes, and a marking member which provides an indication of current vane length and allows a maintenance person to easily determine when a pump replacement is required.
