In-line pump with dry-running motor, TP 40-140/4 A-F-A-BQQE-GX3 98743317

Grundfos TP 40-140/4 in-line pump – reliability and efficiency in a compact housing

The Grundfos TP 40-140/4 pump is a single-stage in-line pump designed for use in heating, air conditioning, potable water distribution systems and in industry. It is characterized by high hydraulic efficiency and a durable construction, which translates into a long service life and low operating costs. The "top-pull-out" design simplifies pump removal for servicing purposes without the need to interfere with the piping installation – saving time and money during maintenance.

Construction and application

The TP 40-140/4 pump has a cast iron housing with an anti-corrosion coating, which ensures corrosion resistance and long-term reliability even in harsh conditions. It uses an asynchronous electric motor cooled by a fan, providing efficient operation. Pipe connections are made using PN 16 flanges, compliant with DIN (EN 1092-2 and ISO 7005-2) standards, which facilitates integration with existing infrastructure. The pump is equipped with a non-relieved mechanical seal with a rubber bellows, compliant with DIN EN 12756, guaranteeing tightness and minimizing the risk of leaks.

• Applications:
  • Heating and air conditioning installations in commercial buildings
  • Potable water distribution
  • Water pressure boosting
  • Industrial processes requiring reliable liquid pumping

Advantages for the installer and end user

• Easy access to working elements: The "top-pull-out" design allows the pump to be removed from the top without disconnecting the pipelines – simplifying servicing and maintenance.
• High corrosion resistance: The electrophoretic coating provides protection against corrosion, extending the pump's life even in an aggressive environment.
• Efficient motor: The fan-cooled asynchronous motor provides efficient operation and minimizes energy consumption.
• Standard connections: PN 16 flanges facilitate integration with the existing piping installation.
• Reliable seal: The non-relieved mechanical seal with a rubber bellows ensures tightness and minimizes the risk of leaks.
• High hydraulic efficiency: Provides optimal fluid flow with minimal energy consumption.
