摘要： A new and improved liquid metering pump for use in pumping sterile fluids and foodstuffs includes a separable autoclavable pump head assembly. The diaphragm-containing pump head may be preassembled as a unit and sterilized to provide a pump head having sterile product contact surfaces. The pre-sterilized pump head may be mounted and connected to an electronic solenoid metering pump and used for delivering fluids in food preparation, medical and pharmaceutical applications.

摘要： A conductivity probe having a modular design. A probe body has a distal end and a proximal end. The distal end includes a recessed portion for providing a seat for an O-ring that seals an electrode tip assembly. The probe body also includes a set of internal threads for engaging with cooperating threads disposed on the electrode tip assembly. The distal end of the body terminates in a bottom wall having an opening leading to a connection pipe attached to a junction box. The exterior of the probe body includes a stepped down profile of varying constant diameters with a side port formed in the probe body for receiving a temperature compensation probe. The probe body includes a set of external threads and wrench flats for installing the probe into a boiler conduit. The design is completely modular with minimal assembly required. The probe body is machined easily and features hard stops for trouble-free assembly. Also, there is no potting of the electrical components required.

摘要： A new and improved diaphragm metering pump is provided with a modular removable drive assembly. The removable drive assembly provides rotation to an eccentric shaft within the pump and is disposed outside rotary bearings for the eccentric shaft and outside sealing elements containing hydraulic fluid in the pump housing. In a preferred embodiment, a readily accessible mechanically activated hydraulic refill valve cartridge is provided to hydraulically balance the diaphragm. In a preferred embodiment, a push to prime air bleeder valve is provided permitting automatic priming of the hydraulic system without requiring disconnection of any valves. The pump is designed to interchangeably receive a number of diaphragm assemblies including an improved leak detection diaphragm and a double-sided leak detection diaphragm. In a preferred embodiment, a diagnostics window is provided permitting visual inspection of the operating condition of various valves connected to the hydraulic system.

摘要： A nonmetallic pump with a gear pump assembly having an adapter spool mounted to an electric motor. The pump assembly is designed to reduce manufacturing costs and to provide access for many service and maintenance tasks to be performed without breaking any of the pipe connections. The pump assembly also includes a splined shaft system and a lubricating fluid circulation system with spiral grooves located inside a pair of bearings disposed on opposite sides of the gear flights. The assembly also includes a replaceable precision liner that surrounds the gear flights to maintain a tight tolerance for optimal performance of the pump. Also, an O-ring disposed inside the front cover of the assembly provides for operation of the pump over a wide temperature variation with relatively loose manufacturing tolerances.
