摘要： A seal chamber housing is provided for equipment with rotating shafts and includes a stepped conical bore open at the pumping mechanism end. The bore defines a seal chamber affording greater volume about the associated mechanical seals and a tapered bushing is optionally sealingly seated in the large diameter end of the stepped conical bore for excluding pump fluid from the seal chamber and/or preventing loss of seal flush liquid from within the seal chamber. In addition, the seal chamber includes upper and lower vent and drain ports primarily for use when the optional bushing is in place and said chamber also includes flushing fluid ports, a closed temperature-controlling external fluid channel and external air cooling features, all of which coact in various operating environments to provide longer and more efficient mechanical seal life.

摘要： A centrifugal pump includes a C-shaped sealing assembly including an annular spring disposed between opposing legs of a base member. The spring biases the legs away from one another into sealing positions. In other embodiments, a vertical pump may be provided so as to include an oil recirculation system which enables an oil-based lubricant to be utilized instead of grease. In still other embodiments, the axial location of a pump shaft may be adjusted by rotating a bearing housing relative to the bearing frame where the two are threadedly connected to one another.

摘要： A centrifugal pump having a system for preventing unscrewing of the impeller off of the pump shaft is disclosed. The impeller is screwed onto the pump shaft via threads having a first thread pitch, and a lock bolt is inserted through the impeller and screwed into the pump shaft via threads having a second thread pitch. The second thread pitch is greater than the first pitch. Accordingly, if the pump motor is operated in the wrong direction, the impeller is prevented from unscrewing because the impeller attempts to move faster axially than the lock bolt which is holding the impeller on the pump shaft.

摘要： A circulating lubrication system for a centrifugal pump, or other rotating equipment utilizing an oil sump, is disclosed. The lubrication system includes an external reservoir located distant from the main lubrication chamber, so that lubricating fluid from the main misting chamber is forced out of the main chamber, cooled and cleaned (i.e. filtered) in the external reservoir, and thereafter fed back into the main lubricating chamber. In such a manner, the lubrication system maintains substantially clean, cool, and moisture free lubricating fluid in the main misting chamber and reduces the required downtime of the device. Thus, the life span of the device is lengthened while at the same time production is increased.

摘要： A pump including a pump shaft bearing lubrication system having a main lubrication chamber (45) and a pair of auxiliary lubrication chambers (55 and 57), the auxiliary chambers being disposed on opposite sides of said main chamber. Pump shaft bearing assemblies (single or double row) are sandwiched between each auxiliary lubrication chamber and the main chamber (45) so that each bearing assembly (31 and 33) has its inner and outer sides simultaneously lubricated by fluid in the main and corresponding auxiliary chamber respectively. Each auxiliary lubrication chamber (55 and 57) is provided with a pair of fluid passageways (61 and 63) interfacing the auxiliary and main chambers so that the lubricating fluid can be circulated from the main chamber (45) to the auxiliary chambers (55, 57) and then back into the main chamber again, thereby constantly lubricating the bearing assemblies with cool, clean, and effective lubricating fluid. Furthermore, a lubricating fluid dispenser (35) is mounted on the pump shaft (7) within the main chamber (45), the dispenser (35) being positioned entirely above the lubricating fluid level such that heat generation within the main chamber is reduced, the dispenser dispersing the lubricant throughout the main chamber by way of an air-flow created by vanes (50, 51) defined in the dispenser.

摘要： A chemical processing centrifugal pump is provided with a triple cartridge seal arrangement including a single inboard seal and a pair of concentric seals located rearward (i.e. outboard) of the inboard seal, the concentric seals being closest to the pump bearings for stability against vibration purposes. The passageway along the pump shaft between the inboard seal and the radially inwardmost concentric seal is filled with a pressurized barrier inert gas so as to create a gas seal while a barrier chamber defined between the concentric seals is filled with a pressurized barrier liquid. Accordingly, the concentric seals are lubricated by the barrier liquid disposed in the barrier chamber while the inboard seal is lubricated by the fluid being pumped. Optionally, the inboard seal may be lubricated by barrier liquid if such a pressurized liquid is used instead of the inert gas to fill the passageway.
摘要翻译：化学处理离心泵设置有三重密封件密封装置，其包括单个内侧密封件和位于内侧密封件的后侧（即外侧）的一对同心密封件，同心密封件最靠近泵轴承，以抵抗振动的目的。在内侧密封件和径向向内最高的同心密封件之间沿着泵轴的通道填充有加压屏障惰性气体，以便产生气体密封，同时限定在同心密封件之间的阻挡室填充有加压的阻挡液体。因此，同心密封件被设置在阻挡室中的阻挡液体润滑，而内侧密封件被被泵送的流体润滑。可选地，如果使用这种加压液体代替惰性气体填充通道，内侧密封件可以被阻挡液体润滑。

摘要： A seal construction is provided for sealing a rotating pump shaft against passage of a fluid along its central axis. The seal construction includes front and rear sealing flanges mounted coaxially to and rotatable with the pump shaft. A temperature stabilized chamber is provided adjacent each sealing flange including means for recirculating and cooling fluid disposed therein so as to maintain the fluid between adjacent engaging members at a substantially constant temperature thereby maintaining a flatness of the sealing engagement between the sealing flange surfaces and the engaging members. The recirculating/cooling system includes a plurality of vanes mounted on and integrally formed with the sealing flange, the vanes causing the fluid within the chambers to flow circumferentially around the pump shaft and exit the chamber by way of an exit orifice, then reenter the chamber through an entry orifice with the fluid being cooled at a location in the circulation line remote from the chamber disposed between adjacent engaging members.
