Oil pumps GPLⅡ/GPMⅡ 60Hz Gear-type GPLⅡ Oil pumps Direct-coupled GPMⅡ ■Applications ●For industry and for transfer of kerosene used in various facilities  (buildings, housings, etc.) ●For transfer of various fuel oils ●For lubrication of various machines ●For transfer of various viscous solutions ■Features ①As the gear is a one-point continuous contact and segmental gear, no liquid is trapped and neither high pressure nor high vacuum is generated, resulting in no noise or vibration. ②The bearing requires no lubrication because of a two-point support structure of a needle bearing and an internal plain bearing and forced self-lubrication. ③As a mechanical seal is used for the shaft seal part, no liquid leak or air suction occurs. ④As the pump has a built-in safety valve, abnormal pressure does not rise. * Please note that the paint color, etc, of the actual unit may partially differ from the photo. ■Description of types ② GPLⅡ - 25 V ① ③ ④ ①Model ③Nominal suction/discharge diameter (25mm) ②Head type L: Low head ④Internal code M: High head ■Standard specifications ■Standard accessories Liquid quality kerosene, light oil, heavy oil A Pumping Motor ……………………………………………………………………………1 Viscosity Viscous liquid (1 - 300mm2/s) liquid Common base …………………………………………………………………1 Liquid temperature 0 - 80°C Safety valve ……………………………………………………………………1 Total suction head −5m Companion flange (20mm or more) ……………………………………2 sets (In case of 20°C) Coupling ……………………………………………………………………1 set Allowable push-in pressure 0.10MPa Coupling cover …………………………………………………………………1 Impeller Gear Structure Shaft seal Mechanical seal Bearing Impeller Needle bearing S45C ■Special specifications Material Motor shaft S45C Type Totally enclosed fan-cooled type, explosion-proof type Motor Casing FC200 Power supply Voltage change: single-phase / 100V, 3-phase / 400V Efficiency Standard efficiency (equivalent to IE1) Starting method Direct-on-Line start Motor Type Increased-safety explosion-proof indoor type Power source 3-phase 200/220V ■Special accessories Synchronous rotation speed 1800min-1 Sluice valve, Check valve, Pressure gauge, Compound gauge Screwed type: 10 - 15mm Connection Strainer (Y type, single, duplex)
