The Multiquip 1841000131 Volute Casing is a genuine OEM component designed for QP-202TH and T-20H series trash pumps. As a direct OEM replacement, it meets the original engineering specifications for these units, ensuring proper hydraulic geometry and impeller clearance are maintained. This part is confirmed to fit QP-202TH and T-20H models, making it a straightforward swap when the original casing is cracked, eroded, or worn from abrasive slurry and debris-laden water. Source it with confidence from DHS Equipment as an authorized Multiquip parts distributor.
Key Features
- OEM Hydraulic Geometry: — Cast to original tolerances so the internal flow path delivers the pump's rated volume and head pressure without compromise.
- Direct Bolt-On Replacement: — Matches original mounting bolt pattern and inlet/outlet dimensions on QP-202TH and T-20H trash pumps for a clean installation.
- Confirmed Fitment: — Verified for QP-202TH and T-20H trash pump models; check your model plate before ordering to ensure accurate application.
- Abrasion-Resistant Construction: — Built to handle the abrasive slurries, sandy water, and solids that trash pump applications routinely demand.
- Restores Full Pump Output: — A worn or damaged volute reduces pressure and flow; replacing with 1841000131 brings the pump back to its intended performance level.
The volute casing is the main pump housing that surrounds the impeller and converts the high-velocity water thrown outward by the spinning impeller into usable pressure. Its spiral-shaped internal chamber is engineered to gradually expand the flow path, slowing the fluid and building discharge pressure efficiently. When the volute casing is cracked, heavily eroded, or otherwise compromised, the pump loses prime easily, output pressure drops, and the unit can no longer move water at the volume the job demands.
