Multiquip 0203020B1174 Outer Pipe

The Multiquip 0203020B1174 Outer Pipe is a genuine OEM component designed for ST3020B1 and ST3020BCUL submersible pumps. As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring a correct fit within the pump housing without any guesswork. Sourced directly through authorized Multiquip supply channels, the 0203020B1174 is the right part for keeping your submersible pump operating as intended on ST3020B1 and ST3020BCUL units.

Key Features

• Genuine OEM Construction — Manufactured to original Multiquip tolerances, ensuring the outer pipe seats and seals correctly within the pump casing.
• Direct-Fit Replacement — Designed to drop into the same position as the original outer pipe, with matching thread pitch, diameter, and length for a straightforward swap.
• Confirmed Fitment — Compatible with Multiquip ST3020B1 and ST3020BCUL submersible pump models.
• Structural Integrity Under Submersion — The outer pipe forms part of the pump's structural and flow path assembly; a damaged or corroded pipe can compromise discharge efficiency and housing stability.
• Correct Material Specification — Built from materials suited to continuous submersed pump operation, resisting corrosion and wear in dewatering and transfer applications.

The outer pipe on a submersible pump forms a core part of the pump's discharge and structural assembly, channeling fluid flow from the impeller through the pump body to the outlet. It also contributes to maintaining the alignment and rigidity of internal components during operation. When the outer pipe becomes cracked, corroded, or damaged, it can disrupt fluid flow, cause pressure loss, and compromise the mechanical integrity of the pump — making timely replacement essential to restoring full pump performance.
