The Multiquip 18141 is a genuine OEM Suction Cover NPT 2" designed for Multiquip centrifugal pump models including QP205SH, QPT205SLT, QP205SLT, QPT305SLT, QP305SLT, QP303B, and QP303H, as well as Whiteman power buggy models WBH-16, WBH-16E, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH-21EF, WBH-21EFP, and WBH21EPA. Sourced directly from Multiquip, this is an exact OEM replacement that installs into the suction inlet port without modification. Confirming the correct part number before ordering is the single most important step in a successful repair — 18141 is the verified reference for these pump and buggy applications.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, ensuring the cover seats and seals correctly at the 2" NPT suction inlet.
- Correct Thread Spec — Machined to NPT 2" thread standard for a leak-free, pressure-rated connection at the pump suction port.
- Broad Verified Fitment — Confirmed for QP205SH, QP303B, QP303H, QP305SLT, QPT205SLT, QPT305SLT, and the full WBH-16 and WBH-21 Whiteman power buggy hydraulic pump lines.
- Maintains Prime Integrity — A properly seated suction cover prevents air ingestion at the inlet, keeping the pump primed and flow rates consistent through demanding continuous-pour or dewatering cycles.
- Direct Drop-In Replacement — Matches the OEM mounting interface exactly, so the cover mounts using existing hardware without rework to the pump housing.
The suction cover seals the inlet side of the pump housing, capping the suction port when not connected to a hose or fitting and forming a pressure-tight boundary when in service. On centrifugal and self-priming pump designs, any air leak at the suction side breaks the low-pressure zone the impeller needs to draw fluid — even a hairline gap at the cover can cause loss of prime, reduced flow, or a pump that runs dry. On the Whiteman WBH buggy hydraulic circuit, the same cover protects the hydraulic pump's suction inlet from contamination and vacuum loss. A cracked, cross-threaded, or missing suction cover should be replaced promptly to protect both the pump internals and operational output.
