DAB 40L Submersible Borehole Motor – 1.5kW (2HP), 3-Phase 230V [Clearance]

The DAB 40L is a 4" submersible borehole motor designed to drive a compatible submersible pump end (wet end) in clean water borehole and well installations. It is suitable for installers, contractors and borehole owners who need to replace or upgrade a motor on an existing 4" borehole pump, and offers robust AISI 304 stainless steel construction and a 250m maximum operating depth rating, making it a practical choice for residential, farm and light commercial borehole systems.

• Application: Drives a compatible 4" submersible pump end in clean borehole or well water
• Key specification: 1.5kW (2HP), three-phase 230V, 50Hz, rated current 7.9A
• Flange: NEMA 4" — compatible with standard 4" submersible pump ends
• Motor only: This listing is for the motor only. No pump end, control panel or cable is included beyond the standard connector lead
• Protection: IP68, insulation class F, max operating depth 250m
• Overload protection: Must be supplied by the installer for this three-phase version — not included

Key Features

• Rewindable-type motor: Can be professionally rewound rather than replaced outright if it ever fails, extending its practical service life.
• AISI 304 / 304L stainless steel construction: Parts in contact with water and the outer stator shell are stainless steel, suited to borehole water conditions.
• Liquid-filled cooling and lubrication: An FDA-approved liquid cools the motor and lubricates the ball bearings for reliable running.
• Ceramic-carbon mechanical seal: Helps keep borehole water out of the motor housing over the long term.
• Removable cable connector: Speeds up maintenance or motor replacement without needing to re-terminate the full cable run.
• Variable frequency drive compatible: Suitable for use with a VFD across a 30–50Hz range, for installations that need flow or pressure control.
• PT100-ready: Can be fitted with an optional PT100 temperature sensor for motor monitoring on larger or critical installations.

Typical Applications

• Replacing a failed or worn motor on an existing 4" borehole pump
• Farm, agricultural and rural borehole water supply
• Domestic borehole-to-tank water supply systems
• Light commercial and irrigation borehole installations

Technical Specifications

What's Included

• 1 x DAB 40L submersible borehole motor (1.5kW, 3-phase 230V) with standard connector lead

Please note: Installation fittings, electrical protection, cartridges, control boxes, cables, unions, brackets, or accessories are not included unless specifically listed above. This motor does not include a pump end (wet end) or control panel.

Installation & Compatibility Notes

This is a motor only and must be paired with a compatible 4" submersible pump end (wet end) rated for a similar power range, matched by a qualified pump installer. Confirm your borehole diameter, static and dynamic water level, required flow rate, total dynamic head, pipe run and power supply before ordering — a motor sized incorrectly for the application can lead to poor performance or premature failure. This three-phase version requires the installer to provide correctly rated overload protection; it is not built into the motor. Suitable for clean borehole or well water only, not for dirty water or sewage applications. Installation and electrical connection must be carried out by a qualified electrician or pump installer. If you are unsure whether this motor is compatible with your existing pump end or borehole setup, contact Zisabo with your details before ordering.
