Support Bracket
A floor-standing support: a spoked disc carried on two cast legs, with the shaft bore machined through the hub.
This is the part that holds the pump off the floor and takes the whole weight of the wet end through two feet. The spokes are not decoration — they are what stops a disc this diameter ringing and flexing under a rotating load.
Cast as one piece, legs included. A fabricated support with welded legs will do the same job until the welds start working loose; on a pump that runs continuously they always do.
| Casting process | Vertical-line sand moulding on two lines (national patent) |
| Materials | Grey iron · ductile iron · WCB carbon steel · CF8M stainless |
| Machined features | Hub bore and face · foot pad undersides · any register the pump locates on |
| Minimum order | 100 pieces |
| Certification | EN 10204 3.1 per heat, spectrometer results |
| Source of geometry | Your drawing, 3D file or a worn sample |
What Is Difficult About This One
Every casting has one or two features that decide whether the batch repeats. On this part they are these.
Spokes and rim cool at different rates
The rim is the last thing to freeze and it pulls on every spoke as it goes. Section is balanced between them so the disc comes out flat rather than dished.
Legs are part of the same draw
Both feet come off the pattern with the disc — no loose pieces, no welding. That is what keeps the hundredth one square to the floor like the first.
Bore is the only tight feature
Everything else is as-cast. The hub bore is machined, and it is machined square to the foot pads in the same set-up.
Alloy Options
The same geometry is a different part in three different plants. Chloride content, abrasion and temperature drive the choice — not the name of the fluid.
| Alloy | Grade | When it is the right choice |
|---|---|---|
| Grey iron | HT200 / HT250 | Default for water duty. Damps vibration, machines easily, lowest cost. |
| Ductile iron | QT450 / QT500 | When the duty is cyclic or the part takes shock. Tougher than grey. |
| WCB carbon steel | ASTM A216 WCB | Higher strength, weldable. For pressure-bearing bodies. |
| CF8M stainless | ASTM A743 CF8M | Chloride and corrosion duty — the cast equivalent of 316. |

What to Send Us
These are the ones specific to this part. A drawing, a 3D file or the worn original covers all of them at once.
| Item | Why it matters |
|---|---|
| Shaft centre height | From the foot pads to the bore axis — the dimension that fixes everything else |
| Hub bore and what sits in it | Bearing, sleeve or the pump spigot |
| Foot pad pitch and hole size | So it drops onto the base you already have |
