A pump includes a cylinder having a lower end formed with a suction pipe; an inlet section including a housing, a lower externally threaded section, an upper externally threaded section, an upper nut secured to the upper externally threaded section, and an inlet having a valve, a first connector having one end connected to the valve, and a second connector having a connection element connected to the valve, a hollow projection opposite to the connection element and provided through the housing, and an axial hole through the hollow projection; a joining section secured to the cylinder and including a hollow first externally threaded section, a hollow second externally threaded section, and a hollow first internally threaded section secured to the second externally threaded section; a manual operation section including a piston rod extending downward from a spring biased handle into the cylinder; and an outlet section.

Provided herein is a valve manifold comprising (a) an elastomer sheet attached to a plurality of magnetic pistons, wherein the magnetic pistons project from a first side of the elastomer sheet; (b) a foot component comprising a first surface and a plurality of shafts that orthogonally pass through the first surface; and (c) a body component comprising a second surface, a groove that laterally passes along the second surface, and a plurality of reservoir channels that orthogonally pass through the second surface, wherein the elastomer sheet is compressed between the foot component and the body component.

A pump system for pumping a coolant fluid for cooled radiofrequency ablation treatment includes a housing having a front, a back, a right side, a left side, a top surface, and a bottom surface, and a plurality of peristaltic pump assemblies. The top surface of the housing includes a central channel between at least two of the peristaltic pump assemblies configured to drain fluid away from the front of the housing. A cooled radiofrequency ablation system additionally includes a pump system and a generator having mating surfaces such that the pump system can sit stably on top of the generator.

Presented and described herein is a stroke system (1) for dosing a fluid from a container (3), comprising a piston pump (5) with a piston (7), so that a fluid can be dosed from a container (3) by displacement of the piston (7), and a temperature control device (29) for controlling the temperature of the fluid to be dosed by means of the stroke system (1).

A pumping device is provided, including: a barrel; a bottom portion, connected to the barrel; a pumping mechanism, configured to drain fluid out from or into the barrel; and at least one wheel, connected to the bottom portion. Whereby, the pumping device can be moved easily.

A hydraulic pumping system in accordance with embodiments comprises a breast interface operably coupled to an actuatable assembly by means of an actuatable assembly interface. The breast interface comprises a distal membrane coupled to a housing to form a fluid reservoir therebetween. The actuatable assembly interface comprises a proximal membrane. The distal and proximal membranes are fluidly coupled via a tube carrying a driving fluid. The actuatable assembly interface is configured to removably couple to the actuatable assembly, in order to operably couple the actuatable assembly to the breast interface. The actuatable assembly interface comprises a fluid shut off mechanism to reversibly shut off fluid communication between the breast interface and the actuatable assembly interface when the actuatable assembly interface is decoupled from the actuatable assembly.
