Grundfos Inline Single Stage - TP (B), (I) model

TP (B), (I)

The TP (B) (I) vertical in-line pump series features a pump housing made of bronze or stainless steel, designed to resist corrosion in hot water recirculation systems and lightly acidic industrial applications. The specially constructed shaft seal chamber optimizes water circulation without the need for external piping, thereby extending the life of the shaft seal.

ADVANTAGES

  • TP (B)/(I) pumps effectively resist corrosion, ensuring long-lasting, high performance.
  • Enhanced efficiency and extended shaft seal life with the use of robust pump shaft and replaceable wear ring.
  • The close-coupled design decreases system sensitivity to impurities in the pumped liquid.
  • These pumps are highly efficient, with low energy consumption and minimal noise.

Key Specifications

  • Liquid temperature: -25 - 140 °C
  • Max. flow: 48 m³/h
  • Max. head: 10 m
  • Max. operating pressure: 16 bar
Grundfos Inline Single Stage - TPE2 (I) model

TPE2 (I)

The TPE2 (I) stainless steel inline pump is equipped with a frequency converter that significantly optimises energy consumption, preventing wasteful operation and extending pump life. This durable unit is suitable for various applications, including hot water recirculation, domestic and commercial water supply, as well as heating and cooling systems.

ADVANTAGES

  • TPE2 (I) automates flow and pressure management using external sensor inputs.
  • Integration is straightforward with the option to mount the CIM (Communication Interface Module) for connections to building management systems (BMS).
  • The front-mounted wiring box provides easy access for quick installation.
  • Electro-coated surfaces offer protection against corrosion, enhancing the pump's lifespan.

Key Specifications

  • Liquid temperature: -25 - 120 °C
  • Max. flow: 36 m³/h
  • Max. head: 25 m
  • Max. operating pressure: 10 bar

PRINCIPLE OF OPERATION

Grundfos inline single-stage pumps are centrifugal pumps where the impeller rotates to move fluid through a closed system. Initially, the pump casing is filled with the liquid. The motor-driven impeller then rotates, forcing the liquid to flow to the volute and into the discharge.

PRINCIPLE OF OPERATION

In-line pumps are centrifugal type pumps, and flow of fluid does not change inside the inline pumps. Before the single-stage centrifugal pump is started, the pump casing is filled with the liquid to be transported for priming. The impeller is then driven by the shaft to rotate at a high speed, and the liquid between the blades must also rotate. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge of the vanes and obtains energy. Liquid leaves the impeller with high speed and enters the volute casing. Here, the liquid decelerates due to the gradual expansion of the flow path, and part of the kinetic energy is converted into static pressure energy. Liquid then flows into the discharge pipe at a relatively high pressure.
