Volute pump cover
The volute shapes the flow leaving the impeller, so its surface and section should be smooth and consistent. The cover also closes the pump, which makes the sealing face and bolt pattern the critical machined features.
We gravity cast volute covers, with cores where the design needs them, then machine the sealing face and fixing holes in house.
Process, alloys and indicative ranges
| Process | Gravity die casting, with cores where needed |
|---|---|
| Typical wall | 4 to 10 mm, indicative |
| Alloys | LM25, LM6 |
| Supplied | As cast or machined |
Ranges are indicative for this kind of part. We confirm process, machine, alloy and tolerances for your design at drawing review.
Critical features and how we check them
| Sealing face flatness | Surface plate check in house |
|---|---|
| Bolt pattern | Functional gauge in house; first article inspection on every new tool |
| Volute surface | Visual inspection in house, at every stage |
| Pressure tightness, when specified | Leak test arranged through a specialist partner |
