125D Deep Well Pressure Pump + 471 injector & 4" housing - 1.4kW 240V 50Hz 1ph incl pressure switch

Description

The Davey 125D Deep Well Pressure Pump + 471 injector & 4" housing is a complete, single-phase jet pump system designed to provide a high-pressure water supply from bores or wells with depths up to 18 metres. This specific configuration is optimized for bores with a minimum diameter of 4 inches (100mm).

Core Technical Profile

Motor Power: 1.4kW (Output), 2.10kW (Input).
Electrical: 240V, 50Hz, single-phase supply with inbuilt thermal overload protection.
Automatic Operation: Includes a factory-fitted pressure switch and pressure gauge for automatic start/stop functionality (requires a pressure tank for effective automatic system use).
Components: This package comes as a complete kit: the 125D pump head, the 471 injector (product code 22471), and the 4" housing.

Performance Capabilities with 471 Injector

This setup balances flow and pressure for depths down to 18 metres. The overall pump is capable of reaching a maximum flow of 126 LPM, while the 471 injector fine- tunes the performance for deeper water:

Maximum Depth: Suitable for suction lifts up to 18 metres.
Max Flow Rate (with 471 injector): Can deliver up to 96 Litres per Minute (LPM) in optimal conditions.
Maximum Pressure: The pump is capable of pressures up to 660 kPa (approx. 66 metres head) depending on operating conditions.
Example Performance: At an injector depth of 12 metres, the pump provides approximately 50 LPM at 310 kPa pressure.
