Pipeline Circulation Pump
Inline Pipeline Circulation Pumps
Pipeline circulation pumps sit directly in the pipe run, so they need no foundation and take up almost no plant floor. That makes them the natural choice for heating, cooling and process loops where the pump is one component in a long circuit rather than a standalone station. The range covers two series: the ISG vertical inline design and the multistage GDL design.
Series overview
- ISG — vertical inline pipeline pump for general circulation duty.
- GDL — vertical multistage inline pipeline pump for higher head in the same footprint.
Published performance range
Flow is published from 1.6 m³/h to 1200 m³/h, head from 5 m to 150 m, with motor power from 0.18 kW up to 132 kW. Because the two series overlap across that envelope, the choice usually comes down to how much head is needed in a given pipe size: the multistage GDL adds stages rather than adding floor area.
Typical applications
- HVAC heating and cooling loops
- Hot water circulation
- District heating networks
- Industrial process loops
- Pipeline circulation and pressure boosting
Frequently asked questions
What is the difference between the ISG and GDL series?
Both are vertical inline designs. ISG is the single-stage circulation pump; GDL is multistage, which delivers higher head within the same pipe-mounted footprint.
What flow and head does the range cover?
Flow 1.6–1200 m³/h, head 5–150 m, and motor power from 0.18 kW to 132 kW.
Do inline pumps need a foundation?
No. Mounted directly in the pipe run, they need no separate foundation, which is the main reason they are used in building services and plant rooms with limited space.
