1、SEFCO 低温泵 To secure best performance at very low Suction Head (NPSH), a Preloading Stage is standardwise integrated in every piston-pump cold-end, pressurizing the liquid to a selected level before entering the high pressure chamber. The cold-end is flanged to the crank-case intermediate part (ser
2、ving as purge chamber) and the piston connected to the drive crosshead by the connection assembly. Most reliable drives of advanced design are used System consisting of the pump driven by a Gearbox-G2 and motor, static frequency converter and electric control box. This system allows selectio
3、n of the two following operation modes: either direct with customer current, 技术咨询李 工180—4633----5235 0595-2876--7930 at constant frequency/pump speed or with static frequency converter, at variable frequency/pump speed. System consisting of the pump, directly driven by a special motor of pr
4、oven design for higher speed, static frequency converter and electric control box. This system, where the motor/pump speed is continuously frequency controlled, works only with static frequency converter fed by external/internal current. lt is a more compact system and the pump/motor-unit, without l
5、ubricated gearbox, has the highest efficiency and hence lowest current consumption. Besides special high-duty apllications with oil-lubricated crank-drive, the oilfree self-lubricated version mostly applies. SEFCO常用配件型号： Sefco密封座H0370 Sefco迷宫套H0119 Sefco H0099 Sefco H0096 Sefco H000
