Model: ISG vertical and ISW horizontal pipeline pumps
ISG and ISW share hydraulics but not layout. How the vertical and horizontal pipeline pumps differ in space, pipework, service and noise.
| Inlet / Outlet Diameter | DN25 to DN400 |
|---|---|
| Material | Cast iron, stainless steel on request |

The ISW is the horizontal version of the pipeline pump. It uses the same impellers and casings as the ISG, so a model number gives the same flow and head in either layout. The choice comes down to space, pipework and service.
| ISG vertical | ISW horizontal | |
|---|---|---|
| Floor space | Very small | Larger, on its own base |
| Height | Taller, motor on top | Low |
| Pipework | Straight through the pump | Suction at the end, discharge on top |
| Large motors | Heavy weight high up | Easier to support |
| Service | Motor and impeller lift out upwards | Accessible from the side |
Three horizontal ISW pumps with 7.5 kW motors were supplied for a dust suppression water system, specified for 30 to 60 m³/h of fresh water at 20 m on 380 V. On a site like that the low profile and the solid base of the horizontal pump suit outdoor installation.
Either layout can be picked from the same model list.
BlogHorizontal 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.
BlogA 3.7 kW vertical inline pump, 25 m³/h at 32 m, ordered complete with counter flanges, bolts and a spare mechanical seal. Why that list is worth copying.
