The Multiquip EM509437 Hose is a genuine OEM replacement built for ST-45HRM and ST-70 submersible pump models. Sourced directly from Multiquip, this hose matches the original component specification so it seats, it seals, and performs exactly as the factory intended. Confirmed fitment for ST-45HRM and ST-70 units means no guesswork when it comes time to get your pump back in service. DHS Equipment stocks this part so you can order with confidence and keep your equipment running without unnecessary delays.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional spec, ensuring the hose maintains correct flow capacity and pressure integrity for submersible pump applications.
- Direct Drop-In Replacement — Engineered to connect at the same ports and mounting points as the original, so installation is straightforward without reworking fittings or lines.
- Confirmed Submersible Pump Fitment — Verified for ST-45HRM and ST-70 models; use your model code to confirm compatibility before ordering.
- Maintains Flow and Seal Integrity — A correctly fitted hose keeps fluid routed efficiently through the pump system; a cracked, kinked, or deteriorated hose leads to pressure loss, leaks, and pump inefficiency.
- Fuel and Fluid Compatibility — Material construction is suited to the fluid types and operating conditions found in Multiquip submersible pump systems, resisting degradation over extended service cycles.
A hose in a submersible pump system is responsible for directing fluid between internal components or from the pump to the discharge point. When a hose cracks, collapses, or develops a leak, the pump loses prime pressure and output efficiency drops — in some cases stopping flow entirely. Replacing a worn hose promptly with a correctly rated OEM component restores the pump's designed output and prevents further damage to seals and adjacent fittings caused by uncontrolled leaks.
