Black Gold Pump & Supply’s Non-Compression (NC) Pumps does not include a traditional standing valve. Instead, the pump design relies on the expansion and contraction of a vacuum zone between the upper plunger and lower barrel (the “production anulus”) to produce fluid. On the downstroke, the production anulus expands and generates a vacuum that unseats the traveling valve(s) below and allows fluid to fill the zone. 

On the upstroke, the same zone contracts and generates a pressure, therefore closing the traveling valve(s) below and unseat the top-open cage. This simultaneously forces the fluid out and upward into the tubing.
