Thermal Oil PumpFBOT 300-340
Large-capacity model for thermal oil circulation up to 350°C in critical industrial systems: refining, chemical, food, textile. Back pull-out construction per ASME B73.1, mechanical seal immersed in bearing oil bath.
Performance Envelope — 1750 rpm
Available impeller diameters
Each pump is supplied with the impeller diameter calculated by FB engineering for the specific duty point — flow, head and thermal fluid of the project.
Thermal oil service up to 350°C
Compatible with Therminol-66, Dowtherm A/G, Mobiltherm 600 and industrial mineral oils. Mechanical seal immersed in bearing oil bath ensures thermal stability under continuous operation. Requires thermal expansion system and nitrogen inerting on charge line (not included in pump scope).
Construction features
- Back pull-out construction — rotating assembly maintenance without disconnecting piping
- Mechanical seal immersed in bearing oil bath — continuous 350°C operation without coke buildup
- ANSI B16.42 flanges (standard) or DIN EN 1092-2 PN16 (optional European)
- Parts list per DIN EN 24250 — spare parts interchangeable with FBCN line
- Hydrostatic test pressure: 1.5× operating pressure
Typical applications
Physical dimensions and detailed curve
FBOT large-capacity models have no individual physical dimensions published in the standard technical manual. Each project receives a dimensional sheet, performance curve specific to the customer thermal fluid and material selection in direct consultation with FB Bombas engineering.
- Dimensional sheet with base, flanges, shaft and shaft end per ASME B73.1
- Performance curve printed for the operational thermal fluid (Therminol, Dowtherm, mineral)
- Material selection (Cast Iron / Carbon Steel / Stainless 316) by thermal compatibility
- Mechanical seal in bearing oil bath + thermal expansion system plan
