A cleaning system for cleaning tubing by circulating balls through the tubing includes a system for separating and recirculating the balls back to the upstream side of the tubing. The separator includes a hollow separator tube having perforations through its wall such that the balls accumulate in a chamber on the outer side of the hollow separator tube while the fluid flows through the interior of the hollow separator tube through a passageway to the atmosphere.
