50 Hz Submersible Borehole Pumps 3 What can you expect from the “Submersible Borehole Pumps Booklet”? The information provided can help you make a -- quick -- first rough selection -- on your own to find a suitable KSB submersible borehole pump for your application.We have kept the volume of the catalogue down to what we think is the absolute minimum. For the 4 to 14 inch range, you will find the following information on the pump selected: -- pump series, size and number of stages, -- motor series, size, power, amperage, and allowable temperature, -- starting method, supply voltage and type...

Voltage [%] Time [s] Run--up Operation Run--down 4s 4s 120 100 80 60 40 20 0 50 Hz Submersible Borehole Pumps 5 Operation of KSB submersible motor pumps with soft starters Soft starter electronically reduce the incoming line voltage and, hence, the initial starting torque and starting current of electric motors. During run--up they gently ramp up the applied voltage to the motor. In the case of submersible motors, the extremely slim design and consequential small moments of inertia result in special characteristics, which differ strongly from normal asynchronous motors. Effects on...

50 Hz Submersible Borehole Pumps 6 Pump Operation with Frequency Inverter In principle, the motors of submersible borehole pumps can also be run on a frequency inverter. As submersible motors differ from conventional standardized motors in terms of bearings, moment of inertia, insulation, temperature increase, loss distribution and heat distribution, the following parameters must be observed: -- Maximum allowable acceleration time (start ramp) -- Maximum allowable deceleration time (stop ramp) -- Minimum frequency -- Maximum operating frequency -- Maximum permissible voltage increase...

50 Hz Submersible Borehole Pumps 7 Typical Installation Positions a) Vertical Installation (deep well, pump sump, etc.) CAUTION: The construction of the well head must meet the relevant regulations of the competent authorities! The unitmust never be installed with its suction strainer exactly at the level of the well screen / filter! Before installing the unit in narrow deep wells we recommend to check narrow boreholes for dimensional accuracy over their entire length, e.g. by inserting a pipe of the length and biggest outside diameter of the pump unit. Sharp bends or bottlenecks can make...

50 Hz Submersible Borehole Pumps 8 Submersible Borehole Pump Selection for Deep Wells Pump Selection The following data are required for a first rough selection of a submersible borehole pump: -- Capacity Q in m3/h (l/s) -- Pressure at well head HA in m -- Well diameter in inches or mm -- Temperature of fluid handled tA in °C -- Pump head HP in m While Q, HA, Dand tA are usually specified by the customer, the head HP to be developed by the pump needs to be calculated. There are two typical applications to be considered (see the drawing on the right): 1. Pumping into an open overhead tank HP...
