22 KW Borehole Submersible Centrifugal Impeller Water Pump

22kw 30hp Submersible Seawater Pumps Anti Corrosive No Pollution For Clean Water

Sea water submersible pump mainly drawing sea water, but seawater is corrosive medium, so we recommend stainless steel material. APK pump factory main stainless steel material for sea water have stainless steel 304, stainless steel 316, stainless steel 316l, duplex stainless steel, stainless steel 904, anti-corrosive.

Corrison Resistant Vertical Submersible Centrifugal Pumps Cast Iron Material

1.) 380V/440v/660v voltage deviation is no more than ±5%,frequency is 50HZ/60HZ, three -phase power deviation is no more than ±1%.

2.) Motor cavity must be filled with clean water.

3.) The first stage impeller of the pump should be more than 2mm below the moving water surface, pump should be less than 70m below the static water level.

4.) The distance from the motor bottom to well bottom must be more than 2 m.

5.) Water temperature should be no more than 110°C.

6.) Sand content of the water no more than 0.01%.

7.) PH value of water 6.5-8.5.

8.) Hydrogen sulfide content of the water should be no more than 1.5mg/L.

9.) Chloride ion content of the water should be no more than 400mg/L.

10.) Water yield of water source should ensure the requirements of pump continuous working

KSB new series of submersible borehole pumps

The series is designed for water supply and irrigation applications as well for use in small systems for drawdown of groundwater levels. It covers discharge heads of up to 550 m and flow rates of up to 21,500 litres per hour. The efficiencies of the hydraulic systems satisfy the demanding requirements of the applicable ErP regulations; all MEI values are above 0.40.

Certified for drinking water to French (ACS) and US (NSF) standards, the pump can safely be used for drinking water applications and all pump components are made of stainless steel. The pump sets are capable of handling water with a solids content of 50 g per cubic metre. An integrated, hydraulically optimized check valve prevents the discharge line from emptying when the pump set is stopped. This reduces any damage that could be caused by reverse rotation of the pump.
