Wacker Neuson 5100044582 Suction Flange

The Wacker Neuson Suction Flange is a genuine OEM component designed for PT4A and PT4A(I) series trash pumps. Sourced directly through Wacker Neuson's authorized parts program, this suction flange meets the same dimensional and material standards as the part originally fitted at the factory. Whether you're completing a planned service or replacing a damaged flange after heavy use, part number restores the pump's intake connection to proper working order. Verified fitment covers the PT4A and PT4A(I) models, so you can order with confidence.

Key Features

• OEM-Grade Sealing Surface — Manufactured to the same dimensional tolerances as the original, ensuring a flush, leak-free mating surface at the pump intake.
• Direct Drop-In Replacement — Matches the original bolt pattern and port diameter of the PT4A and PT4A(I), so installation follows the standard service procedure without modifications to the pump housing.
• Confirmed Fitment for PT4A Series — Verified for PT4A and PT4A(I) trash pumps, covering both standard and international variants within the model family.
• Maintains Full Pump Flow Capacity — A correctly seated suction flange preserves the pump's rated intake volume; a cracked or warped flange introduces air into the suction line, causing cavitation and a sharp drop in output pressure.
• Genuine Wacker Neuson Part — Supplied as an authorized OEM replacement, carrying the same part number — 5100044582 — used by Wacker Neuson dealers and service centers worldwide.

The suction flange forms the primary connection point between the pump's intake port and the suction hose or piping. It creates a sealed interface that allows the pump to draw fluid efficiently without pulling in air — a condition that leads to cavitation, overheating, and accelerated wear on the impeller and volute. When the flange cracks, warps, or develops a damaged seating face, the pump loses prime easily, output drops, and the machine works harder than it should; replacing the flange promptly restores the airtight intake seal and full pumping performance.
