Casing/Volute is the stationary housing in a CIP return pump that converts kinetic energy into pressure energy by gradually expanding flow area.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Volute Type | Single volute (standard), Double volute (for high-pressure applications) | |
| Surface Finish | Ra ≤ 0.8 μm (electropolished optional) | |
| Pressure Rating | Up to 16 bar | |
| Connection Types | Flanged (ANSI/ASME B16.5), Clamp (3A/SMS) | |
| Design Standards | ASME B73.1, ISO 2858 | |
| Temperature Range | -20°C to 140°C |

This component is used in the following industrial products
A specialized pump designed to return cleaning solutions from the CIP system back to the central storage or drain after the cleaning cycle.
A pump that supplies high-pressure water flow to clean and regenerate filtration media in backwash systems.
A mechanical device that moves water through a water supply system by creating pressure differentials.
A practical evidence checklist for RFQ preparation and supplier evaluation.

Manufacturer profiles associated with Casing / Volute.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
316L stainless steel offers excellent corrosion resistance against CIP cleaning chemicals (acids, caustics, sanitizers), has low carbon content to prevent sensitization during welding, and meets food/pharmaceutical hygiene standards.
Single volute has one discharge channel and is cost-effective for standard applications. Double volute has two discharge channels 180° apart, which balances radial loads on the impeller shaft, reducing vibration and wear in high-pressure applications.
Casing wear increases clearance between impeller and volute, reducing efficiency through increased recirculation and pressure loss. Severe wear can cause vibration, noise, and premature bearing failure.
