Abstract
In a system for testing drilling mud, a mixing tank and an aging vessel are hydraulically connected to supply drilling mud to a closed recirculating path through which mud is pumped to measuring instrumentation. The accumulator has a head which is removable for inspection and maintenance of the gas pressurized piston which pressurizes the drilling mud. The seals on the head are positioned to minimize wear.
