GRUNDFOS TPE 32-120/4 A F A BAQE 0.55KW SINGLE STAGE IN LINE 415v 98514395 #1408

GRUNDFOS TPE 32-120/4 A-F-A-BAQE – 0.55 kW 415V Variable-Speed In-Line Circulator Pump (98514395) #1408

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 2-year guarantee.

• Pump type: TP family – dry-rotor, single-stage in-line circulator (single-head)
• Control: variable-speed operation via integrated frequency converter
• Connection: DN32 DIN flanges (PN16)
• Port-to-port length: 440 mm
• Service design: Top-pull-out – power head removable without disturbing pipework
• Shaft seal: BAQE 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)
• 120 – head series designation
• /4 – 4-pole motor
• A – basic version
• F – DIN flange connections
• A – basic version
• BAQE – shaft seal code

What does the BAQE shaft seal code mean?

BAQE describes the mechanical seal materials used in this pump:

• B – rubber bellows seal construction
• A – carbon graphite seal face (impregnated)
• Q – silicon carbide counterface
• E – EPDM elastomers

Seal operating temperature (BAQE): suitable from 0 °C up to 120 °C in water duties (EPDM-limited).

Why choose the BAQE seal?

BAQE uses a carbon against silicon-carbide face pairing. This soft–hard combination gives quiet, low-friction running in clean heating and cooling water, while the silicon-carbide counterface provides excellent stability and wear resistance. It is a proven, widely-used seal selection for HVAC circulation duties where smooth operation and reliability are priorities.

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 PN16 DIN flanges with a port-to-port length of 440 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 better match the duty of the unit being replaced, 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.
