瑞士SEFCO 低温泵

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 serving 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 selection 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 proven 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 lubricated 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 H0006 Sefco B0047 Sefco B0055 Sefco H0252 Sefco A0015 Sefco H0097 SEFCO 密封环支H0543 后密封环B0215 前密封环B0216 片簧G0043 密封座H0370 密封环B0117 O 型圈B0146 支持环B0361 支持环H0297 黑导向环B0118 间环H0373 滚针轴承C0036 滑动轴承H0569 轴密封B0230 垫圈B0228 垫圈B0229 垫圈B0233 高压密封环B0225 密封圈B0146 褐色导向环B0155 密封盘H0099 O 型圈 O Ring 38 x 3 B0055 密封组件H0092 密封衬套H0096 旋转盘 Swirl wheel H0097 垫片 30 24 1 Shim 30 x 24 x 1 A0015 密封片 Seal washer B0047 密封环 Wear ring H0015 迷宫套H0119 涡状轮H0118 迷宫轮H0121 垫圈B0053 垫片A0125 密封圈B0052 密封条B0006 耐磨环H0499 16 耐磨环H0499 41 H0254 C0006 C0032 A0095 G0018 H0076 C0005 A0040 B0030 H0006 B0037 H0214 H0215a H0216a B0172 H0225 B0170 H0099 H0096 H0006 B0047 B0055 H0252 A00115 H0097 H0251 B0006 SEFCO 泵 CL 13 EM 2 2 SEFCO 泵 CL 19 EM 18 5 SEFCO 泵 CL 25 EM 45 SEFCO 泵 CL 19 EM 75 部分参数 Type C 13 and CL 13 Flowrate 10 400 lit min Diff Head 5 200 m Diff Pressure 0 5 20 bar Type C 19 and CL 19 Flowrate 80 800 lit min Diff Head 10 500 m Diff Pressure 1 50 bar Type C 20 and CL 20 Flowrate 100 2500 lit min Diff Head 10 150 m Diff Pre
