摘要： A pumping apparatus for pumping a liquid from a source to a target including a motor and pump driven by the motor. The pumping apparatus further includes a support frame, a swivel platform pivotably mounted on the support frame and a drive assembly connected with the support frame and the swivel platform for pivoting the swivel platform with respect to the support frame, wherein pivoting of the swivel platform by the drive assembly changes an angle defined between a longitudinal axis of the motor and a longitudinal axis of the pump piston, and wherein a spacer is provided for limiting the range of the angle.

摘要： A continuous run controller for a dual control compressor system includes an integrated housing containing a pilot valve and a hydraulic unloader valve. Low pressure in the hydraulic oil system opens the hydraulic unloader valve such that the suction valve unloader assembly unloads the compressor. High pressure in an air receiver of the compressor system opens the pilot valve such that the suction valve unloader assembly unloads the compressor.

摘要： A pumping cassette including a housing having at least two inlet fluid lines and at least two outlet fluid lines. At least one balancing pod within the housing and in fluid connection with the fluid paths. The balancing pod balances the flow of a first fluid and the flow of a second fluid such that the volume of the first fluid equals the volume of the second fluid. The balancing pod also includes a membrane that forms two balancing chambers. Also included in the cassette is at least two reciprocating pressure displacement membrane pumps. The pumps are within the housing and they pump the fluid from a fluid inlet to a fluid outlet line and pump the second fluid from a fluid inlet to a fluid outlet.

摘要： An apparatus for reducing or eliminating gas lock in a downhole pump is provided. The apparatus has a ported bushing connecting to an upper standing valve at a first, uphole end and connecting to a lower standing valve at a second, downhole end. The apparatus also has one or more vents. In one embodiment, the apparatus is coupled downhole of a traveling valve of a downhole pump such that, on each upstroke, the one or more vents of the apparatus draw liquid from the annulus between the pump and the tubing into the passage between the upper and lower standing valves for opening the upper standing valve to accumulate liquid in the pump barrel below the traveling valve. The accumulation of liquid in the pump barrel below the traveling valve breaks gas lock and opens the traveling valve, ensuring the operation of pumping liquid from downhole to surface.

摘要： A piston plug includes a cylindrical body having a longitudinal axis and an outer cylindrical surface. The outer cylindrical surface extends longitudinally between a first surface and a second surface opposite the first surface. The outer cylindrical surface defines a hole extending radially inward. The hole has a central axis perpendicular to the longitudinal axis of the cylindrical body. A first channel and a second channel are defined by cylindrical body. The first channel is in fluidic communication with the first surface and the hole. The second channel is in fluidic communication with the second surface and the hole. The first channel, the second channel, and at least a portion of the hole form a non-collinear flowpath. The piston plug is disposed in a plug hole in a piston and is retained in the plug hole via an interference fit between the piston plug and the plug hole.
