Hot Oil Pumps
Horizontal hot oil / heat-transfer centrifugal pumps for thermal oil circuits without abrasive particles — air-cooled path to bearings, up to +350 °C.
Share
Desan Engineering hot oil / heat-transfer pumps are suitable for heat transfer oils and low-viscosity industrial oils that do not contain abrasive particles.
Horizontal shaft, single-stage volute, end-suction closed impeller centrifugal pumps with back pull-out design: bearing group, seal box, shaft and impeller can be removed without separating the volute from the pipeline.
Highlights
- Natural air circulation provides temperature drop from casing toward bearings
- Radially closed impellers with radial vanes to balance axial force and reduce seal pressure
- High-temperature single mechanical seal
- Grease-lubricated bearings as standard
- Typical use above 100 °C in chemical, petrochemical and food processing heat-transfer circuits
