SKGS High Temperature Centrifugal Pump
The highest temperature rating in the vertical range, for pressurised circulation at up to 240 degrees Celsius.
Overview
What This Pump Does
The SKGS is the high temperature build of the inline body, published for a maximum permissible fluid temperature of 240 degrees Celsius.
Hydraulics match the rest of the vertical family, 1.5 to 1500 m3/h with head to 150 m and drives to 160 kW, so upgrading the temperature rating does not change the installation envelope.

Key Benefits
Temperature Rating Without A Layout Change
240 Degree Fluid Rating
Covers pressurised high temperature circulation above the limit of hot water models.
Same Envelope As The Standard Model
Flange sizes and installation dimensions follow the vertical family, so pipework does not have to be redesigned.
Seal Specified For Heat
Hard alloy mechanical seal faces or a packing gland, chosen against temperature and system pressure.
Inline Mounting
No floor footprint, which matters in energy centres where equipment is already packed together.
Application Scenarios
Where It Is Installed
High Temperature Water Circuits
Pressurised circulation in process plants operating well above 100 degrees.
Heat Recovery Systems
Continuous circulation of recovered heat at high temperature.
Industrial Heating Distribution
Distribution loops where the medium is held under pressure above its atmospheric boiling point.
Who It Is For
- Process plants running high temperature circuits
- Energy and heat recovery contractors
- Engineers replacing pumps that fail at temperature
- Plants standardising on the inline envelope
Problems It Solves
Seal life measured in weeks
A pump rated for the real circuit temperature removes the repeated failure that comes from running past a rating.
Upgrading means re-piping
Because the body matches the rest of the family, the temperature upgrade fits the existing flange positions.
Uncertainty over pressurisation
We ask for design pressure as well as temperature, because above 100 degrees one without the other is meaningless.

Compared With Other Options
| SKGR hot water pump | The SKGR is rated to 120 degrees. Above that this model is the correct selection. |
|---|---|

Use Guide
Running A High Temperature Inline Pump
Confirm Pressurisation
Water above 100 degrees must be held above its vapour pressure throughout the circuit.
Allow For Expansion
Pipe supports and guides must let the line move without loading the pump flanges.
Heat Up In Stages
Gradual temperature rise protects the seal faces and the casing.
Record And Compare
Log flow, pressure, temperature and current when stable, then compare monthly.
Answers
SKGS High Temperature Centrifugal Pump FAQ
What is the maximum fluid temperature?
240 degrees Celsius as published.
Does the flow range change with the temperature build?
No. It remains 1.5 to 1500 m3/h with head to 150 m.
Can it be used on thermal oil?
For thermal oil use the magnetic drive heat transfer line, rated to 350 degrees with no shaft seal.
How is the seal protected at this temperature?
Hard alloy faces plus correct circuit pressurisation and venting. The circuit design matters as much as the seal specification.
Is a horizontal version available?
Yes, the SKWS carries the same 240 degree rating.
