IN-LINE pump with dry-running motor TP 50-900/2-A-F-A-BAQE 22.0 kW 3x400 V 96087185

Grundfos TP Inline Vertical Pumps – Reliability and Efficiency in One

Grundfos TP series pumps are single-stage centrifugal pumps in an inline arrangement, designed for a wide range of applications in heating, air conditioning and water supply systems. They are characterized by a simple construction with a short coupling, which translates to less sensitivity to impurities in the pumped medium compared to pumps with a wet rotor. The TP 50-900/2-A-F-A-BAQE model with a power of 22 kW and a voltage of 3x400V is an efficient solution for demanding installations.

Construction and operating parameters

The pump is equipped with an IE3 motor, which guarantees high energy efficiency and reduced operating costs. The pump housing is made of cast iron GG 25 (GJL-250) and the impeller is made of cast iron GGG 40, ensuring durability and corrosion resistance, especially thanks to the electrolytic coating. This makes the pump suitable for operation in ambient temperatures from -30°C to 60°C and with a medium temperature from 0°C to 120°C. The maximum working pressure is 16 bar, and the connection diameter DN50 allows cooperation with existing infrastructure.

The pump provides a nominal flow rate of 61.1 m³/h and a head of 732.37 kPa (90 meters). The maximum efficiency is also 61.1 m³/h. The motor is three-phase, with a power of 22 kW and a rotational speed of 2945 rpm, the rated current is 39.5 A, the insulation class is F and the efficiency is IE3. The housing is made of cast iron GG25, and the impeller is made of cast iron GGG40 – these materials ensure mechanical strength and corrosion resistance. The pump is ideal for heating, air conditioning, water supply systems and industrial processes requiring reliable liquid transport. The IP55 degree of protection protects the device against dust and water jets, allowing installation in various environmental conditions.

Advantages for installers and users
