Grundfos TP In-Line Pumps

Discover the world’s most comprehensive range of high-efficiency, vertical in-line pumps featuring a mechanical shaft seal. Suitable for both small and large-scale systems, TP pumps provide the necessary flow and pressure for heating, cooling, and air-conditioning applications.

A key feature of the TP pumps is the close-coupled design, where the pump and motor are separate units. This design makes them less sensitive to impurities in the pumped liquid compared to canned rotor pumps. Additionally, the specially constructed shaft seal chamber ensures optimal water circulation without the need for external piping. An anti-corrosion surface treatment enhances durability, providing the longest possible lifespan. Low in noise and capable of withstanding temperatures up to 150°C, TP pumps are a robust and reliable choice.

A wide range of applications covered:

Use the TP pumps for maximum efficiency and reliability in the following application areas:

• Heating
• Cooling
• District energy
• Industrial cooling
• Industrial processes
• Water supply

Features:

• Advanced fan design: Advanced axial fan design means dramatically reduced noise levels. 
• Grundfos Blueflux® IE4: Grundfos Blueflux® motors come standard in TP pumps. The motor on smaller models easily meets IE4 demands, even when accounting for the energy consumption of the integrated frequency converter.
• Compact perfection: The ratio between the length and width of the pump shaft is crucial. Large shaft diameters and a short distance from the impeller to the motor maximize stability and reduce maintenance costs. Grundfos pumps are designed to achieve the optimal proportion between shaft length and width for enhanced performance.
• The all-in-one solution: In Grundfos TP pumps, the coupling and shaft are friction-welded together to form a completely stable mechanical unit, significantly reducing vibration levels. This stable, all-in-one solution extends the lifespan of both the shaft seal and bearings.
• Renewable neck rings: All TP pumps come with renewable neck rings, allowing for easy upgrades when necessary.
• Unique design of shaft seal chamber: There is no need for external piping, as the design ensures optimal water circulation, thereby prolonging the lifetime of the shaft seal.
• Anti-corrosion surface: The cataphoresis surface treatment, which includes Powercron® cathodic electrocoating and zinc phosphate coating, provides maximal protection against corrosion. This treatment on the inside of the pump ensures a longer-lasting internal surface, maintaining high efficiency over time.
• Mechanically and hydraulically balanced impeller: Minimized vibration levels and axial forces contribute to maximized motor bearing and shaft seal lifetimes.
