Abstract
In a hydraulic circuit including a ball circulation pump skid, a single pump, and a set of valves in a manifold of the ball circulation pump skid, the pump and valves are operated to move all fluid in the hydraulic circuit alternately along two paths through an operative device and a ball collection capsule in the manifold, so that none of the balls ever enter the pump. The first path enables (a) ball-containing fluid flow from the operative device to the ball collection capsule and (b) ball-free fluid flow from the ball collection capsule to the exactly one pump and back to the manifold. The second path provides for (c) ball-free fluid flow from the pump to the ball collection capsule and (d) ball-entraining flow from the ball collection capsule to the operative device.
