The Grundfos TPE series is a complete line of electronic inline pumps built for modern industrial and commercial systems. These pumps feature a dry rotor motor and come with a built-in frequency converter, making them ready to plug into your 400V power supply. The series covers a wide range of sizes, from compact TPE 32 models to heavy-duty TPE 200 units, all rated for PN16 pressure. Whether you are upgrading an old circulation loop or designing a new industrial setup, the TPE series gives you reliable flow control and long-term durability without complex external wiring.

Built for Easy Installation

Installers will appreciate the straightforward inline design that fits directly into existing pipe runs. The dry rotor motor keeps electrical components separate from the pumped fluid, which simplifies maintenance and reduces the risk of leaks. Each unit arrives pre-wired with the frequency converter already integrated, so you skip the extra cabinet work and separate VFD mounting. The compact footprint and standard flange connections mean you can swap out old pumps with minimal pipe modifications. Clear labeling and straightforward terminal access save you time on site.

High Efficiency and Smart Control

Every pump in the TPE series carries the IE5 efficiency rating, which means lower electricity bills and less strain on your electrical system. The integrated frequency converter adjusts motor speed in real time to match the exact flow and pressure demands of your system. This smart control prevents energy waste from throttling valves and reduces mechanical stress on pipes and fittings. You get precise flow regulation, quieter operation, and extended pump life, all while staying within modern energy compliance standards.

Reliable Performance in Demanding Environments

Industrial environments demand equipment that can handle continuous operation and varying load conditions. The TPE series is engineered for steady performance across a wide range of flow rates and head pressures. The robust PN16 pressure rating ensures safe operation in high-pressure circuits, while the dry rotor design protects sensitive electronics from moisture and contaminants. With consistent thermal management and proven Grundfos engineering, these pumps deliver dependable service year after year, even in demanding HVAC, process water, and industrial circulation applications.

Quick Selection and System Compatibility

Choosing the right TPE model is straightforward thanks to the clear naming system that matches flow, head, and motor power to your project needs. The series covers everything from small circulation loops to large industrial circuits, so you can find the exact size without over-specifying. All units are compatible with standard control signals and can be easily integrated into building management systems. With fast delivery options and widespread availability of spare parts, you can keep your projects on schedule and your clients satisfied with a pump that just works.
