Injector Jet Kit 472 suit 125D

Description

The Davey Injector Jet Kit 472 (Product Code: 22472) is a crucial component for converting a standard Davey 125D pump into a deep well pressure system, enabling it to draw water from bores with suction lifts up to 30 metres. The kit works by creating a vacuum and increasing pressure to lift water from significant depths.

Components

• A bronze injector and foot valve assembly, which are lowered into the water.
• An adaptor flange (or bend) to connect the suction pipes to the pump.
• A rubber gasket.
• Two polythene connectors.
• Eight stainless steel hose clips.

Function

• The kit allows the pump to function in deep well applications by using a venture effect to supplement the pump's lifting capability:
• Deep water access: It enables the system to draw water from depths well beyond the typical 7.5m limit of shallow well pumps, suitable for bores with a minimum diameter of 4 inches (100mm).
• Performance optimization: The specific 472 injector is designed to balance flow and pressure for depths down to 30 metres, capable of delivering a maximum flow of up to 63 litres per minute in optimal conditions.
• System integration: It works in conjunction with the Davey 125D pump head, which features an Automatic Demand Response (ADR) valve to protect against loss of prime from over-pumping
