Extreme Thermal Duty • Up to 400°C (752°F)

FXT Centerline-Mounted High-Temperature Pumps

Heavy-duty centerline support brackets prevent pump-to-motor misalignment caused by severe thermal expansion at extreme temperatures.

Centerline Mounting • Thermal Growth Compensation

Bi-Directional Thermal Expansion Control

FXT High-Temp Closed Impeller

Support feet positioned exactly on horizontal centerline ensure the casing expands uniformly upward and downward, preserving coupling alignment up to 400°C.

Foot-Mounted vs. Centerline-Mounted Under 400°C Thermal Loads

Centerline Feet Geometry

Conventional foot-mounted pumps expand strictly upward from the baseplate, driving the pump shaft out of alignment with the motor. FXT centerline support keeps the shaft axis fixed.

API 682 Metal Bellows Seals

Operates without elastomer O-rings that degrade or melt above 200°C. Welded high-nickel alloy bellows withstand extreme temperatures with long MTBF.

100% Captive Foundry Traceability

Cast in our Coimbatore foundry in pressure-containing ASTM A216 WCB steel, verified by radiography (RT) and optical emission spectrometry.
