210 m³/h High-Head Borehole Pump for Large Water-Supply Projects

At its rated operating point, the pump delivers approximately:

• 210 cubic metres per hour
• 3.5 cubic metres per minute
• 210,000 litres per hour
• 5,040 cubic metres over 24 hours of continuous rated operation

The daily figure is theoretical. Actual daily output depends on the operating head, well recovery capacity, control strategy and permitted operating hours.

High-Head Performance

The rated head of 300 m is equivalent to approximately 2.94 MPa of water pressure produced by the pump at its rated point. Part of this pressure is consumed by vertical lift and pipeline resistance.

The discharge pipe, flange connection, non-return valve and other components must be selected for the maximum possible system pressure. Buyers should request the pump’s shut-off head instead of designing the pipe only around the 300 m rated head.

Municipal Water Supply

The pump can extract groundwater for centralized municipal or rural water systems. It may discharge into a reservoir, treatment facility, elevated tank or main distribution pipeline.

Industrial Water Transfer

It can supply clean groundwater to industrial storage, cooling-water systems and process-water facilities when the liquid is compatible with the pump materials.

Agricultural Irrigation

The 210 m³/h capacity can serve large irrigation networks, main pipelines and reservoir-filling projects. The well yield and irrigation-system pressure must be calculated before selection.

High-Elevation Delivery

The available head makes this model suitable for locations where water must be lifted over significant terrain elevation or transported through a high-resistance pipeline.

Hydraulic Construction

The pump uses 11 hydraulic stages to increase water pressure progressively. Stainless steel impellers are used inside the cast-iron pump section, combining the structural strength of cast iron with the corrosion resistance of stainless steel rotating components.

The precise material grades and shaft material should be stated in the quotation and technical agreement.

Conditions That Must Be Confirmed

This model should be selected only when the required operating point is close to its approved performance range. Buyers should check:

• Whether the well can sustainably provide 210 m³/h
• Whether the calculated total head is close to 300 m
• Whether the well casing provides adequate clearance
• Whether the power system can start a 300 kW motor
• Whether the water quality is suitable for cast iron and stainless steel
• Whether the rising pipe can withstand the operating and shut-off pressure

The control system should include motor-overload, short-circuit, phase-loss, phase-sequence, abnormal-voltage and dry-running protection. Water-level monitoring is necessary when the well yield or seasonal water level is uncertain.

Pressure, flow, motor current and dynamic water level should be recorded during commissioning.
