Specialty Rod Pumps

Black Gold Pump & Supply’s Barrel Length Plunger Pump is designed to improve pump efficiency and run times in the presence of sand, scale, and/or trash. The plunger assembly is designed to keep sand in suspension and to prevent sand from settling between the plunger and barrel. The plunger is wiped clean after every down stroke, mitigating the possibility of a stuck pump. Traveling and standing valve cages have a double valve to increase the potential run life of the pump.

Black Gold Pump & Supply’s Double Displacement Pump is ideal for applications involving restricted pump bore size due to small casing diameters. The pump increases production without having to up size the pump bore or pumping unit. On the upstroke, fluid is produced like a normal tubing pump. On the down stroke, the added production is pushed into the production tubing. These pumps are all double valved for improved run life.

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.
