High Temperature & Circulation Pumps Manufacturer & Supplier

OVERVIEW

High Temperature & Circulation Pumps Selection Guide

High-temperature and forced circulation pumps handle thermal oil, hot water, and process fluids at elevated temperatures. Features include centerline mounting, thermal expansion compensation, and specialized sealing for continuous high-temperature service.

Common Applications

Thermal oil heating systems
Chemical reactor circulation
Boiler feed and condensate
District heating networks
Bitumen and asphalt processing

Typical Media

Thermal oil (mineral/synthetic)
Hot water and steam condensate
Molten salts and heat transfer fluids
Bitumen and heavy oils
High-temperature chemical solutions

Key Standards

API 610 (high-temp designs)
ISO 2858
DIN 24256
CE/PED certified

SELECTION CONSIDERATIONS

How to Choose the Right Pump

Thermal Expansion

Centerline mounting essential above 150C to accommodate casing expansion. Use piping loops or expansion joints to absorb thermal growth.

Seal Cooling

Plan 23 cooling loop for 150-250C; Plan 32 external flush above 250C. Consider magnetic drive for temperatures above 300C to eliminate seals.

NPSH Calculation

High-temperature fluids have high vapor pressure. Calculate NPSHa at operating temperature, not ambient. Elevate supply tank or use booster pumps.

Material Selection

Carbon steel to 350C; 316SS to 450C; alloy steels for higher temperatures. Impeller and shaft materials must match casing thermal expansion.
