GRUNDFOS TPE 32-180/2 A F A BUBE Circulator Pump 98514428 230v #2463

GRUNDFOS TPE 32-180/2 A-F-A-BUBE – 230V Variable-Speed In-Line Circulator Pump (98514428) #2463

This listing is for a Grundfos TPE pump from the TP family of dry-rotor, single-stage in-line circulator pumps. It is a single-head, electronically speed-controlled unit with identical in-line suction and discharge ports, designed for heating, cooling and industrial circulation duties where energy-optimised variable speed operation and serviceability are important.

Condition: supplied as surplus / unused stock. The unit may show cosmetic marks consistent with storage. It is inspected prior to dispatch.
Guarantee: supplied with our standard guarantee.

• Pump type: TP family – dry-rotor, single-stage in-line circulator (single-head)
• Control: variable-speed operation via integrated frequency converter
• Connection: PN6/10 DIN flanges – DN32 (port-to-port 280 mm)
• Service design: Top-pull-out – power head removable without disturbing pipework
• Shaft seal: BUBE mechanical seal

Important commissioning note:
This TPE pump is typically commissioned using Grundfos GO Remote (via MI interface). Correct control mode and setpoints should be configured on site to suit the application.

Frequently Asked Questions

What does the model number mean?

• TP – TP pump range (dry-rotor in-line circulator)
• E – electronically speed-controlled pump (integrated frequency converter)
• 32 – nominal diameter of inlet and outlet ports (DN32)
• 180 – head series designation
• /2 – motor version code
• A – basic version
• F – DIN flange connections
• A – basic version
• BUBE – shaft seal code

What does the BUBE shaft seal code mean?

• B – rubber bellows seal construction
• U – tungsten carbide seal face
• B – carbon, plastic-impregnated counterface
• E – EPDM elastomers

Seal operating temperature (BUBE): 0 to +120 °C

Why choose the BUBE seal?

The BUBE seal uses a tungsten carbide against carbon-impregnated graphite face pairing. This combination provides the wear resistance of tungsten carbide together with the self-lubricating, low-noise properties of carbon. Compared with hard/hard pairings, it offers better behaviour in hot water and significantly improved tolerance to brief dry running, making it a proven and reliable choice for HVAC circulation duties.

What liquids can this pump be used with?

This pump is typically suitable for clean circulation liquids compatible with EPDM, such as:

• Heating system water meeting accepted water quality standards
• Cooling and chilled water circuits
• District heating water
• Condensate
• Softened water
• Clean industrial circulation liquids compatible with EPDM

Not suitable for:

• Liquids containing solid particles or fibres
• Flammable liquids
• Mineral oils or synthetic oils
• Strong chemicals or solvents that attack EPDM
• Sea water or aggressive saline solutions

Does this pump need to be commissioned?

Yes. This is an electronically controlled TPE pump and is typically commissioned using Grundfos GO Remote. The correct control mode, setpoints and operating limits should be configured during installation.

Is this suitable to replace other DN32 circulators?

This model uses DN32 DIN flanges with a port-to-port length of 280 mm. Where dimensions match, it can replace other DN32 in-line circulators (for example from Wilo, Lowara and KSB), subject to hydraulic duty and control compatibility. The advantage of a variable-speed circulator is that it can be tuned during commissioning to adjust the previous duty, rather than being locked to a fixed-speed curve.

Can the motor be removed without draining the system?

Yes – the pump uses a top-pull-out design, so the power head can be removed while the pump housing remains installed in the pipework.
