Blog316 Stainless Pump Casing on a Cast Iron Base: A Practical Mix
Horizontal pipeline pumps built with a 316 stainless steel casing and a cast iron foot. Why you only need stainless where the liquid touches the pump.

Model: IRG40-160A, 50-125(I), 80-200A, 65WQK25-15-2.2
IRG40-160A, 50-125(I) and 80-200A hot water pipeline pumps in one order with four 65WQK cutter pumps. Why one supplier for both made sense.
| Flow Rate | 5.9 to 47 m³/h |
|---|---|
| Head | 20 to 44 m |
| Power | 1.5 to 11 kW |
| Material | Cast iron |

A machinery and electrical supplier ordered pumps for one project in a single contract: three sizes of hot water pipeline pump for the building services, and four cutter submersible sewage pumps for drainage.
| Pump | Rated duty | Motor | Qty |
|---|---|---|---|
| IRG40-160A pipeline pump | 5.9 m³/h at 28 m | 1.5 kW | 2 |
| 50-125(I) hot water pipeline pump | 25 m³/h at 20 m | 3 kW | 2 |
| 80-200A hot water pipeline pump | 47 m³/h at 44 m | 11 kW | 1 |
| 65WQK25-15-2.2 cutter sewage pump | 25 m³/h at 15 m | 2.2 kW | 4 |
The hot water pumps carried the TQR names the buyer used; hydraulically they match our 50-125(I) and 80-200A builds.
