NTT Centrifugal Pumps for Optimal Operational Safety

Special design with effective thermal barrier

We know that pumping hot fluids can be challenging. You can overcome it with NTT centrifugal pumps designed specifically for pumping mineral oil-based organic heat transfer fluids. The special pump design with an effective thermal barrier effectively reduces the temperature at the seal and in the fluid leakage.

High Mechanical Stiffness

The high mechanical stiffness of the pump between the casing and the bearing bracket ensures high operational reliability and long wear part life. Other safety features, such as a packing behind the impeller, effectively minimize leakage in the event of a shaft seal malfunction. Decisive advantages for the safety of your plant.

EASY MAINTENANCE

Special Bearing & Sealing Design

Pumps of our NTT family do not require external liquid cooling of the shaft seal despite high operating temperatures. This not only reduces operating costs, but also eliminates the need for additional cooling equipment. In addition, the use of a shaft seal allows for easy maintenance of the centrifugal pumps and provides long-term cost savings by eliminating the need for specialized sealing systems. Another aspect of NTT’s ease of maintenance is the use of standard wear parts, such as the two roller bearings. These wear parts are available worldwide and allow efficient maintenance of your pump.

OPTIMAL INTEGRATION

NTT Pumps for Efficient Installation

We understand that heat transfer equipment is used in a wide variety of systems. For optimal integration of the pump into your system, we offer three variants. In addition to the horizontally installed NTT series, where the pump and drive motor are coupled on a common baseplate, we also offer the close-coupled NBT and NIT in-line pump series, which can be installed horizontally or vertically and are ideal for limited installation space.
