241 Rotary pump US09539533 2000-03-31 US06328547B1 2001-12-11 Kazuo Morita
A rotary pump has a simple construction by omitting a transmission shaft on the side of a motor and whereby makes a cost of the rotary pump as low as possible, with maintaining feature that assembling and disassembling is facilitated. The rotary pump has a main casing, a casing cover cooperated with the main casing for defining a pumping chamber therebetween, a pair of rotors received within the pumping chamber with mutually meshing pumping segments for synchronous revolution in mutually opposite directions, a space being defined in one portion of the casing cover, a cover piston being disposed within the space for movement back and forth with respect to an end surface of the rotor, and an air cylinder being mounted on the casing cover and having a piston rod, to which the cover piston is connected.
242 Displacement pump and method of use thereof US09048184 1998-03-26 US06174152B1 2001-01-16 Kay Rokman; Raine Suurnakki
A displacement pump for a relatively high pressure performance environment includes a casing with first and second ends, with rotors driven in the casing to effect pumping. Flushing fluid (such as sealing water or substantially fiber-free foam) is introduced into a clearance between the rotors and the interior surface of the second end of the casing to keep the clearance substantially free of undesirable particles or fibers, typically fibers (such as glass fibers) having greater abrasiveness than cellulose fibers, or fibers (such as synthetic fibers, or synthetic material coating cellulose fibers) having poorer heat resistance than cellulose fibers. The flushing fluid may be introduced into the clearance in a number of different ways as long the clearance is kept substantially free of the undesirable particles or fibers. The flushing fluid is introduced, preferably through a check valve, at a pressure at least slightly higher than the output pressure of the pump.
243 Gear pump for use in an electrically-operated sealed compressor US421476 1999-10-20 US6116877A 2000-09-12 Yoshiharu Takeuchi; Kiyoji Aburaya; Toshiharu Yasu; Masahiro Tsubokawa; Manabu Sakai; Shoji Aoshika; Tsutayoshi Narita
A gear pump is used in an electrically-operated sealed compressor. The compressor includes a compression mechanism, an electric motor for driving the compression mechanism, and a crankshaft for transmitting the rotational force of the electric motor to the compression mechanism. The gear pump includes a pair of gears being in mesh with each other, one of which is connected to one end of the crankshaft, and a pump casing accommodating only the pair of gears. The pump casing together with the gear pair is disposed on one side of a cover plate, while other elements constituting the gear pump are disposed on the other side of the cover plate. By this construction, the distance between the gear pair and an auxiliary bearing to which the gear pump is secured can be reduced and, hence, an undesirable whirling of one end portion of the crankshaft can also be reduced.

245 Rotary drainage pump lubrication device and separator US925381 1992-08-04 US5259741A 1993-11-09 Kozaburo Nitta
A device to separate muddy water from slurry which is being drained away and a means to use said muddy water to both seal and lubricate a gap between the guide channels and the vanes of the drainage pump, thereby securing the efficient long-term functioning of the pump. The invention presupposes the use of a vane type rotary drainage pump connected to a separation means which is set up to remove muddy water from the slurry discharged from the discharge port. A pressure chamber is incorporated into said rotor and connection with the inner ends of each of said guide channels. The muddy water separated out by the separation means is fed back into said pressure chamber.

Method and apparatus for on-site cleaning of a gear pump by coupling the gear pump outlet to the gear pump inlet and to the inlet end of the passage and which bypasses the bearing and is preferably controlled by a valve element which can block off the bypass in normal operation and be opened for a cleaning operation to increase the pressure on the side of the bearing connected to the inlet and thereby increase the velocity of the flushing stream.
247 Rotary apparatus having passageways to clean seal chambers US664814 1991-03-05 US5096396A 1992-03-17 Elmer S. Welch
Improvements are disclosed in a rotary, lobar, positive-displacement pump and in a rotary, centrifugal pump, whereby all product-contacting areas of the pumps can be effectively cleaned without disassembly, i.e., cleaned in place. Non-rotating seals seal the impellers and isolate the pump shafts from the product zone. Each seal has an elastomeric member molded integrally thereto. The seal is biased by the elastomeric member so as to be slidably pressed against an impeller. In the lobar pump, certain passageways can be selectively closed and opened, so as to adapt the pump for being used to pump a pumpable material when closed and for being cleaned by a cleaning solution flowing therethrough when opened. Valves may be alternatively provided for analogous purposes.
248 Magnetic pump US624307 1975-10-20 US3986797A 1976-10-19 J. David Kopf
A pump is provided in which the fluid being pumped is used to lubricate the moving parts of the pump and the flow path of the fluid through the pump insures that at least a portion of the fluid circulates around the moving parts of the pump to assure efficient lubrication and rapid flushing of the pump. The pump is driven by a pair of concentric magnets, the interior magnet being sealed off relative to the outer magnet.
249 Gear pump US38958473 1973-08-20 US3876349A 1975-04-08 SVENSSON SVEN HILDING
Means are provided to permit relative axial displacement between one of the two gear wheels and a wall of the pump chamber, whereby the sealing engagement between this wheel and wall is interrupted. A device is operable independently of above-normal pressure in the pump chamber to effect this displacement and thereby establish a free passage through the pump chamber.
