A self-cleaning transfer gear pump for transferring molten metal includes the following features: a transfer conduit extends upward from an outlet of a base, two rotatable gears are formed of refractory material and disposed in the gear chamber and engage each other during rotation. A boss functioning as a bearing extends from the drive gear and is adapted to be received in an opening in the base. A shaft is fastened at a lower end to the drive gear. A filter is fastened to the base so as to cover the inlet and prevents particles and objects in the molten metal from entering the gear chamber. In operational mode, a motor rotates the shaft and the drive gear whereby the drive gear and the second gear engage each other while being rotated so as to positively displace molten metal from the inlet to the outlet and along the transfer conduit to the remote location. In self-cleaning mode, the motor rotates the shaft and the drive gear effectively to draw molten metal from the transfer conduit by positive displacement, through the outlet, and toward the inlet therefore cleaning the filter by removing the particles adhering to the filter. Also included are a system with optional filter and optional self-cleaning mode but including an inlet portion of a die casting machine, and a method for operating the gear pump. A flow sensor may be used to transmit pulses into and from the transfer conduit so as to enable determination of a volume of molten metal being charged. The control of the molten metal volume being charged is not solely controlled by the flow sensor. |

A lubricant vane pump for providing a pressurized lubricant for an internal combustion engine includes a pump housing, a pump chamber, a shiftable control ring comprising a pressure-relief-valve, a pump rotor, a pretensioning element which pushes the control ring into a high pumping volume position, a control chamber, and a pump outlet cavity fluidically connected to the control chamber. The pump chamber comprises pump compartments which rotate from a charge to discharge zone. The control ring envelops the pump chamber. The pump rotor comprises radially slidable vanes which rotate in the control ring to provide the pump chamber with the pump compartments. A high lubricant pressure in the control chamber moves the control ring into a low pumping volume direction against the pretensioning element. The pressure-relief-valve of the control ring connects or disconnects the control chamber with one of the pump compartments between the charge zone and the discharge zone. |

A macerator pump apparatus (MPA) includes a waste valve assembly (WVA), a macerator assembly, a pumping assembly, and a quick disconnect discharge assembly (QDDA). An inlet port of the WVA receives waste matter from a waste holding tank (WHT). A valve member positioned within the WVA directs flow of the waste matter to the macerator assembly and isolates the waste matter within the WHT by closing the valve member before the MPA is disassembled for maintenance. The macerator assembly macerates the waste matter and transfers the macerated waste matter to the pumping assembly and to a discharge port of the QDDA. A quick disconnect member detachably connects an outlet plumbing pipe to the discharge port via a quick disconnect valve (QDV) for discharging the macerated waste matter. The QDV isolates the macerated waste matter within the outlet plumbing pipe by closing the QDV before the MPA is disassembled for maintenance. |

A diameter of a main bearing member 12m is defined as Dm, a length thereof is defined as Lm, a diameter of the eccentric bearing member 11e is defined as De and a length thereof is defined as Le. A ratio (=Lm/Dm) of the length and the diameter of the main bearing member 12m and a ratio (=Le/De) of the length and the diameter of the eccentric bearing member 11e are set to Le/De≦Lm/Dm≦1. Therefore, contact at edge portions of both ends of the eccentric bearing member 11e does not occur, and it is possible to prevent contact at edge portions of both ends of the main bearing member 12m even if the main shaft 13m inclines, and to reduce a viscosity loss caused by oil 9a. Hence, the present invention provides a scroll compressor securing reliability of the bearing members 12m, 11e and 16s and having high efficiency. |

In a method for transporting nanofibrillar cellulose in the form of viscous liquid dispersion, the nanofibrillar cellulose is unloaded from a container (3) through a discharge point (3b) which is the lowermost point with respect to the volume of nanofibrillar cellulose in the container at least at the time of unloading. The nanofibrillar cellulose is unloaded and transported to a target location along a pipe (2) using a progressive cavity pump (P2) operating on a positive displacement principle with the suction side of the pump at a distance from the discharge point (3b). The discharge of the nanofibrillar cellulose is ensured by selecting the distance (L) of the suction side of the pump (P2) from the discharge point (3b) so short that the nanofibrillar cellulose flows from the container (3) by the effect of the pump suction, or pressurizing the nanofibrillar cellulose in the container (3) to such a pressure (p) that it will flow at the selected distance (L) of the suction side from the discharge point by the common effect of the pressure of the nanofibrillar cellulose and the pump suction. |
