The Multiquip EM509371 Hose is a genuine OEM replacement designed for the ST-45HRM submersible pump. Sourced directly from Multiquip, this part meets the original design specifications for the ST-45HRM, ensuring a correct fit without guesswork.

DHS Equipment supplies this part as a direct OEM component, so you receive exactly what the machine was built with.
Key Features
- Genuine OEM Construction — Manufactured to the exact material grade and dimensional spec of the original hose, maintaining proper flow capacity and pressure integrity within the pump system.
- Direct-Fit Replacement — Engineered to connect at the same ports and routing path as the original, allowing straightforward installation on the ST-45HRM.
- Confirmed ST-45HRM Fitment — Verified for the Multiquip ST-45HRM submersible pump; always confirm your model before ordering.
- Maintains Flow Performance — A properly seated, undamaged hose keeps fluid moving through the pump circuit without restriction or bypass, preserving rated output.
- Prevents Fluid Loss and Pump Strain — A deteriorated or cracked hose allows leakage that reduces pump efficiency and can cause the motor to run harder than designed, accelerating wear.
A hose in a submersible pump system carries fluid between internal components or directs discharge flow, depending on its position within the circuit. When a hose cracks, collapses, or separates at a connection point, the pump loses prime or pressure, and performance drops noticeably. Replacing a worn hose with a genuine OEM part like the Multiquip EM509371 restores the intended flow path and keeps the ST-45HRM operating as designed.
