The Multiquip EM509373 Hose is a genuine OEM replacement designed for ST-45HRM and ST-70 submersible pumps. Sourced directly from Multiquip, this hose meets the original design specifications for these pump models, ensuring a correct, secure connection without guesswork. As an authentic OEM component, it is the same part installed on these units at the factory, giving operators confidence in both fit and long-term durability. Verified fitment covers the ST-45HRM and ST-70 series, making it a direct service replacement for units in the field.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications for consistent sealing and fluid transfer performance in submersible pump applications.
- Direct Drop-In Replacement — Engineered to connect to the same ports and fittings as the original hose on the ST-45HRM and ST-70, allowing straightforward installation during routine service.
- Confirmed Fitment — Verified for use on Multiquip ST-45HRM and ST-70 submersible pumps, eliminating compatibility uncertainty when ordering service parts.
- Sustained Flow Integrity — A properly functioning hose maintains consistent fluid routing within the pump system; a cracked, kinked, or deteriorated hose can restrict flow, cause leaks, and reduce pumping efficiency.
- OEM Part Number EM509373 — Cross-reference this number against your parts manual or service record to confirm you are ordering the correct component for your unit.
The hose on a submersible pump serves as a critical fluid-routing component, directing water or liquid through the pump system efficiently and without leakage. On units like the ST-45HRM and ST-70, maintaining hose integrity is essential to achieving rated pump output — a hose that has cracked, softened, or lost its seal at connection points will cause pressure loss and can allow contaminants to enter the fluid path. Replacing a worn hose with a genuine OEM part restores the system to its original operating condition and prevents secondary damage caused by uncontrolled leaks.
