Description
Overview:
This Volute Casing is a direct replacement housing for the Koshin SEH50X petrol water pump. It forms the scroll-shaped chamber around the impeller, guiding water from the impeller outlet to the discharge port to maintain pressure and flow. Manufactured as a robust cast aluminium alloy body with a smooth internal profile, it offers a good balance of strength, corrosion resistance and low weight for mobile pump use on site or around the garden. Made to match the geometry of the original unit for alignment and sealing, it is identified by MPN 011 3175. This is a Non-Genuine (aftermarket) part designed to fit the Koshin SEH50X and restore pump performance when the original casing is worn, cracked or eroded.
Key Features:
- Precision fit for the Koshin SEH50X, matching OEM mounting points and clearances
- Cast aluminium alloy construction for durability, corrosion resistance and efficient heat dissipation
- Smooth volute passage helps maintain pump efficiency and stable discharge pressure
- Direct replacement design accepts the original impeller, seal arrangement and fasteners
- Lightweight yet strong housing suited to portable pump use in demanding environments
