Online Pump TP 50-120/2 A-F-A-BQQE-FW1

The Grundfos TP 50-120/2 A-F-A-BQQE-FW1 inline pump, reference 98279255, is a single-stage centrifugal pump designed for applications in heating, cooling, and water distribution systems in commercial and industrial buildings. This pump offers exceptional performance and an optimised design that allows for easy maintenance and high durability, making it ideal for demanding applications requiring continuous and efficient water flow.

Top pull-out design for easy maintenance:

One of the main features of the Grundfos TP 50-120/2 is its top pull-out design, which allows the pump head (including the motor, head, and impeller) to be disassembled without disconnecting the system pipes. This design greatly facilitates maintenance and repair, reducing downtime and costs associated with complete equipment disassembly. This type of design is especially useful in industrial applications where maintenance time is crucial to avoid prolonged service interruptions.

High-quality and durable materials:

The pump is made with high-quality materials that ensure excellent durability and resistance to corrosion. The pump body is made of EN-GJL-250 cast iron (ASTM Class 35), ensuring a solid and robust structure for high-performance applications. Additionally, the pump impeller is made of stainless steel EN 1.4301 (AISI 304), providing superior resistance to corrosion and wear, even when used with aggressive liquids or in demanding conditions.

The pump's mechanical seal is designed to comply with the EN 12756 standard, ensuring effective and reliable sealing during operation. The pump is equipped with an unbalanced rubber bellows seal, offering excellent sealing performance and contributing to the overall durability and efficiency of the equipment.

Hydraulic performance:

The Grundfos TP 50-120/2 pump offers a nominal flow rate of 17.3 m³/h and a nominal head of 8.1 m, making it an ideal choice for applications requiring constant flow and stable pressure. With a nominal speed of 2840-2870 rpm, the pump ensures efficient performance in systems needing to move large volumes of water quickly.

The actual impeller diameter of 87 mm and its optimised design allow the pump to achieve efficient water circulation with low energy consumption. Additionally, the pump is suitable for a wide range of liquid temperatures, with an operational range of -25°C to 120°C, making it ideal for both heating and cooling systems.

Installation and connection:

The Grundfos TP 50-120/2 pump is designed for inline installation, meaning the suction and discharge ports have the same diameter, facilitating integration into existing piping systems. The pump connection is made via DIN PN 6/10 flanges according to EN 1092-2 and ISO 7005-2 standards, ensuring a secure and standardised installation.

With a port-to-port length of 280 mm and a connection size of DN 50, the pump is easy to install in standard piping systems, reducing the need for additional adaptations. Moreover, its maximum working pressure of 10 bar ensures that the pump can operate safely in applications with high pressures.

Electrical data and energy efficiency:

The Grundfos TP 50-120/2 is equipped with a high-efficiency asynchronous motor that complies with the IE3 energy efficiency class, ensuring low energy consumption and optimised performance. The nominal motor power is 0.75 kW, allowing the pump to deliver powerful performance with reduced energy consumption.

The motor is designed to operate with a nominal voltage of 3 x 220-240D/380-415Y V at a network frequency of 50 Hz, ensuring compatibility with most standard electrical installations. The motor also features an IP55 protection class, protecting it against dust ingress and water jets, ensuring a long service life and safe operation in demanding industrial and commercial environments.
