It All Began with an IdeaExperience since 1871
The global success story of KSB began over 140 years ago when Johannes laid the foundation for the company by inventing his “boiler feed apparatus”.
Production of Valves since 1872 Pumps since 1873

Reducing Total Cost of Ownership also means:
Utilising the availability capabilities of the components
Ensuring normal operation = extending service life = saving costs

SES in PracticePower station
Initial situation Operation of two 10-stage high pressure pumps
– Flow rate Qopt. 340 m3/h
– Discharge head Hopt. 1,743 m
– Power PW 1,785 kW– Speed of rotation n 2,985 min-1
– Density ρ 914 kg/m3
Identification of possible savings to reduce the energy costs of the pumps
47
SES in PracticePower stationOptimisation - Solution A Hydraulic coupling High peripheral costs due to pump base plate modifications

TheoryKSB Service: Retrofit (KWP)
KSB Solution KWP
– Wear resistant material– Non-clogging channel
impeller– Lower NPSHr– Higher efficiency up to
90%– No need for civil work

材質 A532 標準不鏽鋼KSB 特殊耐磨耗材料 Noriloy® with Cr-Carbides 由我司工廠特
殊鑄造由 KSB 材料實驗室開發,專為耐磨蝕狀況設計,於 FGD 相關製程
有大量實績。轉速 6 極馬達 : 1150 rpm 原始設計 8 極馬達 : 890 rpm
較低轉速可以降低磨耗速度,延長使用壽命。
NPSHr 9.5 m 原始設計 5.5 m 較低的 NPSHr 可以避免氣蝕,延長葉輪使用壽命。
效率 615 kW, 86% 原始設計 520 kW, 90% 馬達較小,消耗功率較少,操作費用大幅降低。
設計 背拉式設計 原始設計 背拉式設計 一般相較於他牌的渣漿泵設計,背拉式在保養上較為簡易。
磨耗保護 耐磨環 原始設計 耐磨板耐磨板較不易卡住,且在日後若有效率下降,可以利用特殊設計回覆
一定效率。葉輪設計 密閉式葉輪 原始設計 不阻塞型葉輪 增加葉輪前後距離,以利顆粒通過
葉輪,並保持高效率。
施工- - 中心支撐 減少改造工程,換裝容易。- - 底座 舊有底座延續使用,將提供新的馬
達座給新設備。- - 基礎 無須重新製作基礎
