500 m³/h Deep Well Submersible Pump with Copper Pump Head and Stainless Steel Motor Housing for Seawater Supply

The SLAPK 300QJH500-65 is a deep well submersible pump featuring a copper pump head and a stainless steel motor housing. Its model designation indicates a nominal flow of 500 m³/h and a nominal head of 65 m, providing a starting point for large-volume water supply selection.

This configuration can be evaluated for groundwater extraction, irrigation water supply, and industrial water transfer. The required duty point should be checked against the model-specific performance curve, with the material grades and motor specification confirmed in the quotation.

The supplied configuration combines a copper pump head with a stainless steel motor housing. For procurement, these materials should be identified separately so the quotation accurately describes the assembly.

The exact copper material and stainless steel grade should be stated in the technical specification. Impeller, shaft, fastener, and seal materials should also be confirmed where they affect suitability for the pumped water. This configuration should not be described as an all-stainless-steel pump.

A pump in the nominal 500 m³/h flow class can be considered for projects with substantial water demand, such as irrigation reservoir filling, centralized groundwater extraction, and industrial utility water transfer.

The source must be able to sustain the selected pumping rate. For a well installation, provide pumping-test results and the expected dynamic water level. For other intake arrangements, provide the water-level range and installation layout so submergence and motor cooling conditions can be reviewed.

The 65 m nominal head should not be interpreted as the permitted well depth. Selection must account for the elevation difference from the pumping water level to the delivery point, pipeline losses, and any pressure required at the destination.

At this flow level, pipeline sizing is an important part of the selection. Provide the pipe length, internal diameter, material, and main fittings so the proposed pump can be checked against the system requirement. The pump outlet size alone should not determine the diameter of the entire discharge line.

A complete quotation should identify the motor power, electrical supply, material grades, outlet connection, cable length, and control equipment. Confirm the pump assembly dimensions and installation requirements against the actual site.

For a clearly defined scope of supply, specify whether discharge pipework, valves, control equipment, and other accessories are required. Where performance documentation is needed, state the required duty point and request the corresponding curve and agreed test report.
