High-Temperature End-Suction pump

Product Introduction The Series is the high-temperature, heavy-duty evolution of the standard IS end-suction pump. It is specifically engineered with advanced cooling features and heat-resistant components to provide exceptional reliability when handling hot water, thermal fluids, and other high-temperature industrial liquids. Built on a robust, long-coupled platform, the Series is the definitive choice for the most demanding applications, including boiler feed, condensate return, and industrial process heating.


Design Philosophy & Construction The pump enhances the proven long-coupled design with critical features to manage and withstand extreme heat.

  • Robust Long-Coupled Platform: The pump and motor are mounted as separate units on a rigid, shared baseplate. This heavy-duty configuration is ideal for continuous 24/7 operation and allows for easy maintenance through its back pull-out design, where the entire rotating assembly can be removed without disturbing the motor or piping.
  • Engineered for High Temperatures: The pump incorporates several key upgrades to ensure long life in hot applications:
    • Bearing Frame Cooling: The bearing housing is often equipped with an integrated cooling water jacket. By circulating a small amount of external cooling water, heat conducted from the hot pump casing is effectively removed, protecting the bearing lubricant and extending bearing life.
    • High-Temperature Mechanical Seal: The pump is fitted with a specialized mechanical seal that uses advanced, heat-resistant materials like flexible graphite and hard faces like Silicon Carbide to provide a durable, leak-free seal at high temperatures.
  • Centerline Mounting: For applications with very high temperatures, the pump casing is centerline-mounted. This ensures that the pump shaft remains perfectly aligned as the casing expands with heat, preventing excessive wear on the seal and bearings.

Key Features & Benefits

  • Reliable High-Temperature Operation: The combination of a specialized seal and an actively cooled bearing housing allows the pump to operate continuously and reliably with hot liquids.
  • Extended Bearing and Seal Life: The cooling system dramatically lowers the operating temperature of the pump’s most critical wear parts, leading to fewer failures and longer maintenance intervals.
  • Built for Heavy-Duty Service: The robust, long-coupled construction is the most durable configuration for demanding, high-temperature industrial processes.
  • Maximum Serviceability: The back pull-out feature allows for quick and easy maintenance of the entire rotating assembly, minimizing plant downtime.
  • Stable Performance: The centerline mounting design maintains pump alignment across a wide range of operating temperatures, ensuring smooth and efficient performance.

Common Applications The Series is the workhorse for high-temperature fluid handling in industrial settings:

  • Boiler Systems: A primary choice for boiler feedwater and hot condensate return applications.
  • District Heating: Circulating hot water in large-scale municipal and industrial heating networks.
  • Industrial Process Heating: Handling hot water, thermal oils, and other process fluids in chemical plants, refineries, and manufacturing facilities.
  • Food & Beverage Production: Pumping hot water, wort, and other high-temperature liquids.
  • Textile and Paper Industries: Circulating hot process fluids for drying and heating.
