摘要： Described are embodiments of a pump that can be used, for example, in liquid chromatography applications. The pump includes a seal wash housing, pump head and seal assembly. A wear-resistant coating applied to a sealing surface or gland of the pump head or seal wash housing improves the hardness and chemical compatibility of the sealing surface. Oxidation of the sealing surface is reduced so that the sealing surface is less abrasive to the seal assembly and the lifetime of the seal assembly is increased.

摘要： Pumps used in liquid chromatography applications employ actuators for pressurizing and moving liquid. An actuator includes a pump head having a chamber, a gland, a movable rod extending through the gland into the chamber of the pump head, and a plunger seal disposed in the gland around the rod for sealing against fluidic leakage from the chamber. The plunger seal has an annular flange that provides an OD (outer diameter) seal against the gland. The flange defines a seal cavity. The pump head further includes an outlet port and an outlet channel. One end of the outlet channel is in communication with the outlet port and the other end of the outlet channel opens into the seal cavity of the plunger seal. The outlet channel provides a flow path for liquid in the chamber to travel towards the outlet port in response to movement of the rod.

摘要： Described are embodiments of a pump having a diagnostic port that enables users and support personnel to diagnose the source of a pump leak. The diagnostic port is monitored visually or with a pressure or liquid detection sensor. In some embodiments, fluid detected at the diagnostic port corresponds to a leak around a circumference defined at an outer sealing surface of a high pressure seal. In other embodiments, fluid detected at the diagnostic port corresponds to a leak around a plunger at the inside diameter of the high pressure seal. Multiple diagnostic ports can be provided to allow separate determinations of leaks about the different portions of the high pressure seal. The embodiments may eliminate the need to disassemble the pump to determine the source of leaks. Thus the effort required to diagnose and repair the pump can be substantially reduced, and fewer misdiagnosed components are ordered or replaced.
摘要翻译：描述了具有诊断端口的泵的实施例，其使得用户和支持人员能够诊断泵泄漏的来源。诊断端口可以直观地或通过压力或液体检测传感器进行监视。在一些实施例中，在诊断端口处检测到的流体对应于在高压密封的外部密封表面处限定的圆周周围的泄漏。在其他实施例中，在诊断端口处检测到的流体对应于在高压密封件的内径处的柱塞周围的泄漏。可以提供多个诊断端口以允许单独测定围绕高压密封件的不同部分的泄漏。这些实施例可以消除拆卸泵以确定泄漏源的需要。因此，可以显着减少诊断和修理泵所需的努力，并且更少地错误诊断的部件被排序或更换。

摘要： Low-pressure mixing of fluids includes a pumping system having a pump and a fluidic inlet port through which fluid is introduced to the pump. A fluid proportioning system is in fluidic communication with the fluidic inlet port of the pumping system to deliver thereto a fluid stream comprised of multiple different fluids. The fluid proportioning system includes a manifold having a plurality of inlet ports, an outlet port connected by tubing to the fluidic inlet port of the pumping system, and an outlet conduit providing an internal fluidic passageway to the outlet port. Each inlet port is fluidically coupled to a fluid source to receive one of the different fluids and to the outlet conduit to deliver thereto the received fluid for delivery out of the manifold through the outlet port to the fluidic inlet port of the pumping system.
