摘要： Certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) are used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfactants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

摘要： A chemical liquid supplying apparatus capable of discharging chemical liquid with high accuracy and monitoring a leakage of an incompressible medium from a region between a piston and a cylinder is provided. A pump has a flexible tube for partitioning a pump chamber and a drive chamber, and the incompressible medium is supplied to the drive chamber by the piston reciprocating within a cylinder hole of the cylinder. A first bellows cover for forming a first seal chamber is provided between a large-diameter piston portion and the cylinder, and a second bellows cover for forming a second seal chamber is provided between a small-diameter piston portion and the cylinder. To detect pressure of the incompressible medium enclosed in the seal chambers, a seal-chamber pressure sensor is attached to the cylinder, and a deterioration degree of seal members is determined by detecting the pressure.

摘要： A hydraulically driven multicylinder diaphragm pumping machine for pumping difficult-to-pump materials comprises pump cylinders each having at one end (20) an inlet/outlet (21) for fluid material to be pumped supplied under adjustable pneumatic pressure, and at the other end (30) an inlet and outlet (31,32) for hydraulic oil. A separator (40) movable to-and-fro inside the pump cylinder (10) is connected to the fluid-material end of the cylinder by a bellows-like flexible diaphragm (45) and to the fluid material end (30) by another bellows-like diaphragm (46) leaving an outer annular space (49) that contains hydraulic fluid. The total volume of pumping hydraulic oil in the cylinders (10.1-10.12) is maintained constant and equal to ½ the total displacement volume of the cylinders by a device (65) that compensates for thermal expansion and controls the necessary return flow of hydraulic oil for driving the pump. The separators (40) move with an intake stroke at constant speed for all cylinders, and with pumping strokes function of the hydraulic oil delivery, so a lesser number of separators (40) effect an intake stroke while a greater number of separators (40) effect a discharge stroke.
