In-line pump with dry-running motor, TP 150-155/4 A-F-A-BQQE-NX3 98908267

Grundfos TP in-line pumps – efficient solutions for various installations

The in-line pump with dry-running motor, model TP 150-155/4 A-F-A-BQQE-NX3, is a single-stage volute pump designed for operation in heating, air conditioning, potable water distribution systems and in industry. The characteristic design with a short coupling and PN 16 flanges allows for easy integration of the pump into existing pipelines. Made of high-quality materials and with an electrolytic coating, it provides increased corrosion resistance, which translates into long life and reliability.

Construction and benefits of use

Grundfos TP pumps are distinguished by a design that allows for top removal (so-called top-pull-out). This significantly facilitates maintenance and servicing – there is no need to disassemble the entire pump from the installation, just pull out the drive head. Equipped with an unburdened rubber bellow seal compliant with DIN EN 12756, it ensures tightness and minimizes the risk of leaks. The asynchronous motor cooled by a fan is characterized by quiet operation and high energy efficiency (models with IE3 class motors are available).

• Easy access to service elements: The top-pull-out design minimizes downtime during maintenance.
• High hydraulic efficiency: Ensures optimal flow and reduces energy costs.
• Increased corrosion resistance: Electrolytic coating protects against the harmful effects of external factors.
• Versatility of application: It will work in heating, air conditioning, water supply and industrial installations.
• Safety and reliability: The seal compliant with DIN EN 12756 guarantees tightness and long-term operation.
• Quiet operation: The fan-cooled motor ensures comfortable use.

Specification and application

The TP 150-155/4 A-F-A-BQQE-NX3 pump is designed to operate in systems requiring water pressure boosting or closed-loop circulation. Thanks to its design, it is ideal for vertical mounting directly on the pipeline, which saves space and simplifies installation. It can be used both in new installations and in the modernization of existing systems. The selection of the appropriate Grundfos TP pump model should be adapted to the specific requirements of a given application, such as flow rate, head and medium temperature.
