Why Engineers Choose Flowline FTX Over Water-Cooled Pumps

No Cooling Water Infrastructure

Eliminates auxiliary piping, cooling water pumps, scale formation, and water disposal costs. The pump cools itself completely through natural convection air ribs.

Zero Water Ingress Risk

Traditional water-cooled heat exchangers can leak cooling water into the hot oil system, causing violent steam explosions. Air cooling completely prevents this risk.

Back Pull-Out Maintenance

Complete rotating element and seal can be removed for inspection without loosening suction or discharge pipe flanges or disturbing pump alignment.
