    • A priming pump for fluid delivery arranged with a base defining a flow inlet, a flow outlet, and a control valve positioned therebetween. The priming pump includes a housing assembled to the base with an inlet flow valve positioned in an inlet valve compartment and an outlet flow valve positioned in an outlet valve compartment. The valve compartments are in communication with a plunger chamber including an axially movable plunger. A spring-biased control knob is assembled to the plunger and to the control valve for controlling its position between either a direct-flow orientation or a by-pass orientation. With the control valve in the by-pass orientation, upward movement of the control knob draws fluid into the inlet valve compartment and into the plunger chamber. The down stroke of the control knob pushes the fluid out of the plunger chamber.
    • 用于流体输送的起动泵,其布置有限定流入口,流出口和位于其间的控制阀的基座。 起动泵包括组装到基座的壳体,其具有定位在入口阀室中的入口流动阀和定位在出口阀室中的出口流量阀。 阀室与包括可轴向移动的柱塞的柱塞室连通。 弹簧偏置的控制旋钮组装到柱塞和控制阀上,用于控制其在直流取向或旁路取向之间的位置。 随着控制阀处于旁路方向,控制旋钮的向上运动将流体吸入入口阀室并进入柱塞室。 控制旋钮的下降行程将液体推出柱塞室。

    • A disposable, all-plastic centrifuge rotor for fluid processing includes a unitary, molded plastic upper rotor portion that includes a rotor shaft spud. A unitary, molded plastic lower rotor portion is provided and is joined to the upper rotor portion so as to define a hollow rotor interior. Positioned within the hollow rotor interior is a unitary baseplate that is joined to the lower rotor portion and includes a rotor shaft spud. The rotor shaft spud of the unitary baseplate extends through the lower rotor portion and beyond the lower rotor portion and is coaxial with the rotor shaft spud of the upper rotor portion. A spiral vane element is positioned in the rotor interior and is captured between the upper rotor portion and the baseplate for fluid processing as the centrifuge rotor rotates at a high RPM rate.
    • 用于流体处理的一次性全塑料离心机转子包括一个整体的模制塑料上转子部分,其包括转子轴杆。 提供了一体的模制塑料下转子部分并且连接到上转子部分以便限定中空转子内部。 定位在中空转子内部的是一体的底板,其与下转子部分接合并且包括转子轴轴。 整体底板的转子轴突出部分延伸穿过下转子部分并超出下转子部分,并与上转子部分的转子轴轴同轴。 螺旋叶片元件位于转子内部并被捕获在上转子部分和底板之间用于流体处理,因为离心机转子以高RPM转速旋转。
