Abstract: Disclosed is a work for oilwell plunger pumping under a packer system used to increase the wear life of API ball and seat valves and of ball and seat valves seat utilizing a piston actuator mechanism to unseat the ball from the seat, which during operation, create turbulent flow within the housing to increase force to move piston actuator like rifle bullet or weighted blow dart in dynamic high velocity high impact in stages to overcome hydraulic head and surface tension between ball and seat. Also disclosed umbrella shaped disks on the piston actuator for increased force to be used in both insert and tubing type down hole plunger oil well pumps. The labyrinth of fluid passages that are rectangular channels not holes help keep ball off its seat for complete down stroke and keep solids in suspension to prevent plugging of API ball in API valve cage.

Abstract: A tank that may include an inner containment membrane defining a containment volume, an exterior structural shell enclosing the inner containment membrane, and a contingent containment membrane sandwiched between the shell and the inner membrane. The tank may further include a first insulation layer between the contingent membrane and the shell, and a second insulation layer between the inner membrane and the contingent membrane. The tank may further include first or second insulation layers that include a reinforcing beam comprised of foamed or block insulation.

Abstract: Disclosed is a standing valve containing a ball, in which during operation, the ball is moved by ball guides to a position off center and yet not impinged against the valve, and in which unequal fluid flow areas are created around the horizontal circumference of the ball. Further disclosed are pumps utilizing such a standing valve.

Abstract: Disclosed is a system used to increase the wear life of ball and seat valves and of ball and seat valves utilizing a piston mechanism to unseat the ball from the seat, which during operation, create turbulent flow within the valve preventing sand and other wear causing debris from collecting on and prematurely wearing pump components. Also disclosed is a wear and alignment bushing for ball and seat valves utilizing a piston to unseat the ball which reduces stress on the piston actuator.

Abstract: Disclosed is an assembly for unseating a seated traveling valve ball, and pumps utilizing such an assembly. The assembly generally includes a tubular member having therein a piston with an actuator for engaging the ball. Mechanical advantage is provided either by providing a sealing area of the piston that is greater than the sealing area of the seat valve and/or by providing a engaging member suitable to strike to seated ball asymmetrically with respect to the vertical axis through the center line of the ball.

The assembly generally includes a tubular member having therein a piston with an actuator for engaging the ball. Mechanical advantage is provided either by providing a sealing area of the piston that is greater than the sealing area of the seat valve and/or by providing a engaging member suitable to strike to seated ball asymetrically with respect to the vertical axis through the center line of the ball.
