Abstract: A device has a gate portion for recovering floating materials on liquid surfaces and for following vertical movement of the liquid level. Gate floats around and rotatable about the gate portion retain the gate portion near the liquid level. Main floats outside the gate floats support a recovery portion. A blade-shaped projection on an outer circumferential part will rotate along the liquid level. A driving device rotates the gate float, with loads of the driving device being supported by the main floats.

Abstract: A solid-liquid separator prevents wear of a self-priming liquid pump connected to a cyclone mechanism and a solid-liquid mixture can be purified at low cost. The separator separates sludge in the liquid by a cyclone in a separation portion directly or indirectly connected to a suction of the upstream side of the pump. The separation portion has a first and second cyclones with the first cyclone disposed in said second cyclone coaxially. A tank disposed under the cyclones collects separated from the liquid.

Abstract: An oil-water separator with a self-priming pump of high oil-water separation ability enables a mixed liquid to be introduced into the oil-water separator without causing emulsification. A separator portion separating a mixed liquid includes a rough cyclone separation portion. A main separation portion downstream of the rough separation portion performs main separation according to specific gravity. A water discharge portion connected to the main separation portion discharges water. An oil storage tank stores the oil separated from the water and overflowing the main separation portion. A self-priming liquid pump connected downstream of the separator portion and connected to the water discharge portion sucks the mixed liquid from an exterior to enable venting and discharging of air.

Abstract: The present invention provides a filtration device combined with self-priming pump in which a filter replacement work is easy and safe, and removal of air inside of a pump and priming are not necessary.

Abstract: A liquid pump has a sealing mechanism utilizing magnets. The sealing mechanism includes an annular rotating seal attached to the lower surface of a rotary base member fixed to the motor rotating shaft. Additionally, a flexible stationary seal is joined and separated with respect to the rotating seal. Movable magnets are disposed on the rotary base and are adapted to be displaced by centrifugal force due to a rotation of the rotary base member. A stationary magnet is disposed on the upper-surface side of a vertical sliding member to which the flexible stationary seal is fixed. The flexible stationary seal utilized has a cylindrical body. At the upper and lower end portions and the side surface portion, connecting portions to the stationary and movable members are formed. The middle portion has an elastic portion is formed on it.

Abstract: A recovery pump capable of reliably recovering floating oil and/or floating matter such as scum or the like while being significantly down-sized. A pump casing is provided in a lower section thereof with a suction passage and a discharge passage. The suction passage is horizontally arranged and has a suction opening and the discharge passage is horizontally arranged below the suction passage. The passages are arranged so as to communicate with each other through a through-hole and the discharge passage is provided therewithin right below the through-hole with an impeller, which is driven by a drive motor located on an upper section of the pump casing. The suction opening is provided with a recovery section for recovering the floating oil and/or floating matter.

Abstract: An oil-water recovering and separating apparatus for separating a raw fluid consisting of a mixture of oil and water into an oil part and a water part on the basis of difference in specific gravity, comprising: intake means for taking in the recovered raw fluid; a separation tank for separating the taken-in raw fluid; a water-part reservoir tank continued to the separation tank; a drain tank continued to the water-part reservoir tank; an oil part recovery portion disposed in the separation tank, the oil part recovery portion having a recovery port disposed slightly above the fluid level of the raw fluid in the separation tank; and scrape-up means provided in a position facing the recovery port so as to move along the fluid level.

Abstract: A self-priming chemical pump which comprises: a pump portion including at least an impeller and a shaft supporting the impeller; a self-priming mechanism portion including a self-priming chamber which is provided in the discharge side of a vortex chamber of the impeller so as to communicate with a discharge opening, and a suction chamber which is provided in the suction side of the vortex chamber of the impeller so as to communicate with a suction opening; a seal wall which is provided in the vicinity of the discharge side of the vortex chamber to form a slight gap along the outer circumference of the impeller; and a circulation hole which is provided in the self-priming chamber so as to be located inside the outer circumference of the impeller.

Abstract: A container is supported floating in a liquid by floats; an inflow gate is loosely fitted about the container. The inflow gate has a sloping face for introducing liquid into the container. A discharge is provided for discharging the liquid accumulated in the main body bath. Floating substances collected on the sloping face of the inflow gate are raked and pushed into the main container by a raking machine arranged on the sloping face of the inflow gate and a pressure screw arranged on the sloping face of the inflow gate and a pressure screw arranged in the main container.

Abstract: A magnet pump is provided with a heat insulating member arranged between a shaft serving as the rotating axis and an impeller or a magnet can, heat conduction cut-off grooves on a heat conducting path, and a safety lock mechanism. These elements ensures to prevent frictional heat, even if generated due to abnormal operating conditions such as a non-load operation, from being conduted to parts with lower heat resistivity such as the impeller and the casing, deflection in rotation caused by looseness due to thermal expansion, and accordingly the magnet pump is protected from damages.

Abstract: A multi-stage metallic pump or chemical pump with plural impellers arranged in series. The impeller of the 1st-stage is integrally provided with radial flow ribs on the under surface of the impeller and with backside radial ribs on the upper surface of the impeller, which are larger than the front radial flow ribs as regards the diameter of the circle formed by the tips of the respective ribs. A flange is formed as an extension beyond the circumference of the 1st-stage impeller and is integrally provided with a protruding ring on the upper surface of the flange. The protruding ring rotates in a fixed recess formed in a casing, with a certain gap kept. Because of the rotation, the liquid which flows into the clearance between the fixed wall of the casing and the rotating ring creates a turbulent flow there, preventing movement of air there through.
