The Multiquip EM509400 Hose is a genuine OEM hose designed for ST-45HRM and ST-70 submersible pumps. As a factory-authorized replacement, this hose is produced to the exact dimensions and material specifications of the original component, ensuring a correct, leak-free connection every time. Verified for use on ST-45HRM and ST-70 series equipment, it eliminates the guesswork of sourcing a compatible hose from the aftermarket. DHS Equipment supplies this part direct from Multiquip, so you can be confident you are receiving the right component for your machine.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional standards, ensuring the hose maintains correct flow capacity and pressure integrity within the pump system.
- Direct-Fit Replacement — Engineered to the same routing, end fitting, and diameter specifications as the original, allowing straightforward installation without modification.
- Confirmed Fitment — Verified for ST-45HRM and ST-70 submersible pumps, so you can order with confidence using part number EM509400.
- Fluid Transfer Integrity — A properly functioning hose maintains consistent flow between pump components; a cracked or degraded hose can cause pressure loss, bypassing, or pump cavitation that reduces output.
- Fluid System Safety — In submersible applications, a compromised hose can introduce air ingestion or allow uncontrolled leakage, making prompt replacement with a correct OEM part especially important for safe, predictable operation.
The hose on a submersible pump directs fluid through the internal circuit, maintaining the pressure and flow rate the pump is designed to deliver. When a hose develops cracks, softening, or connection failures, it disrupts that flow path — causing reduced pumping efficiency, air ingestion, or visible leakage that can bring operations to a halt. Replacing a worn hose with a genuine OEM part like the Multiquip EM509400 restores the original flow path geometry and connection integrity, keeping the ST-45HRM and ST-70 performing as intended.
