<p>A dispense head assembly include a bung adapter (200), a body receiver (300), and a dispensing body (500). The bung adapter (200) inserts into a drum (20). The body receiver (300) selectively inserts into the bung adapter (200), and the dispensing body (500) selectively inserts into the body receiver (300). A single, unobstructured, uniform-diameter flowpath routes fluid from the drum (20) into a chamber (560) within the body receiver (300). A moveable piston (700) within the chamber selectively blocks fluid flow between the fluid flowpath and a dispense opening (566) on the dispensing body (500). The body receiver (300) and the dispensing body (500) are key matched, for safe and rapid coupling and decoupling.</p> |
