The Multiquip EM97048 Large Relay is a genuine OEM component designed for ST-45HRM and ST-70 submersible pumps. As a direct OEM replacement, this relay is built to the same specification as the original, ensuring correct electrical switching behavior within the pump's control circuit. Verified fitment covers the ST-45HRM and ST-70 models, so you can order with confidence knowing this is the right part for your equipment.
Key Features
- Correct Switching Specification — Genuine OEM construction ensures the relay operates at the proper coil voltage and contact rating required by the submersible pump's electrical system.
- Direct Plug-In Replacement — Matches the original terminal configuration and housing dimensions for a straightforward swap into the existing relay socket.
- Confirmed Fitment — Engineered specifically for Multiquip ST-45HRM and ST-70 submersible pumps.
- Protects Motor and Controls — A properly functioning relay ensures the pump motor is switched cleanly under load, preventing the arcing and voltage irregularities that can damage downstream components.
- Electrical Safety Compliance — Using the correct OEM relay maintains the integrity of the pump's control circuit, reducing the risk of unsafe switching faults in wet or demanding pump environments.
A relay is an electrically operated switch that controls a high-current circuit — such as a pump motor — using a lower-current signal from the control system. In submersible pump applications, the relay handles the repeated start and stop cycles of the motor, absorbing the electrical load each time the pump activates or shuts down. When a relay fails or degrades, symptoms typically include the pump failing to start, running continuously without responding to controls, or erratic on/off cycling that can stress the motor windings over time.
