Overview
The TD series sits vertically on the pipework — inlet and outlet on the same axis, motor on top, no separate baseplate required. That makes it the default for plant rooms where floor space is at a premium, and it explains why HVAC specifications regularly call for “inline circulation” — this family is the answer.
Cast-iron housing with bronze or SS304 impeller options, double mechanical seal that can be replaced without disconnecting the piping, ISO 2858-compatible dimensions.
Typical Applications
- HVAC chilled-water and hot-water circulation
- Closed-loop heating boosting
- Commercial boiler circulation
- Industrial clean-water circulation
- Cooling-tower clean-side circulation
- Solar thermal primary loop
- Pool circulation
- Process-water transfer
