Multiquip 1736190320 Motor Frame

The Multiquip 1736190320 Motor Frame is a genuine OEM component designed for ST4, ST6, ST41230, ST41460, ST61230, and ST61460 submersible pump models. As a direct OEM replacement, this motor frame is sourced and manufactured to the exact specifications required by Multiquip's submersible pump lineup, ensuring a correct fit without guesswork. Verified fitment across the ST4 and ST6 series makes this the right choice when restoring a pump to full working order.

Key Features

• Genuine OEM Structural Integrity — Manufactured to the same dimensional tolerances as the original, maintaining the precise alignment between motor and pump components that the ST series demands.
• Direct-Mount Replacement — Designed to install in the same position and orientation as the factory frame, supporting a straightforward swap during motor service or rebuild.
• Broad ST Series Fitment — Confirmed compatible with ST4, ST6, ST41230, ST41460, ST61230, and ST61460 submersible pump models, covering both single- and dual-voltage configurations.
• Protects Motor Alignment — A sound motor frame keeps the motor shaft and impeller in proper alignment; a cracked or damaged frame leads to vibration, bearing wear, and accelerated pump failure.
• Electrical Safety Compliance — As a structural housing component surrounding the motor assembly in a submersible application, a correctly specified OEM frame maintains the integrity of the motor's water-tight enclosure.

The motor frame is the structural housing that surrounds and supports the electric motor inside a submersible pump. It holds the motor in precise alignment with the pump's impeller and volute, and it forms part of the sealed enclosure that protects the motor from the water it operates in. When a motor frame cracks, corrodes, or becomes physically damaged, that seal is compromised — leading to motor flooding, shaft misalignment, and ultimately pump failure. Replacing a worn or damaged frame with a genuine Multiquip part restores the structural foundation the motor depends on to run safely and efficiently.
