Grundfos TPE 65-340/2 Pump Circulator 415v 96096584 DN65 5.5kW #4031 Used

GRUNDFOS TPE 65-340/2 A-F-A-BAQE – 5.5 kW 415V Variable-Speed In-Line Circulator Pump (96096584) #4031 (Used)

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 a used pump. The unit has been previously installed/used and will show cosmetic wear consistent with service use. It is inspected prior to dispatch. Guarantee: supplied with a 6-month guarantee.

• Pump type: TP family – dry-rotor, single-stage in-line circulator (single-head)
• Control: variable-speed operation via integrated frequency converter
• Connection: PN16 DIN flanges – DN65 (port-to-port 360 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)
• 65 – nominal diameter of inlet and outlet ports (DN65)
• 340 – maximum head (dm)
• /2 – 2-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 (antimony impregnated) seal face
• Q – silicon carbide counterface
• E – EPDM elastomers

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

Why choose BAQE?
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 retaining the chemical stability of a silicon-carbide counterface. It is the standard choice for modern HVAC circulation duties where smooth operation is more important than extreme abrasive resistance.

What liquids can this pump be used with?

This pump is typically suitable for clean circulation liquids compatible with the pump materials and 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

Water/glycol mixtures are permitted (ethylene or propylene glycol), but the allowable temperature and concentration depend on operating conditions. Refer to the Grundfos glycol chart in the manual for the correct temperature and glycol percentage limits.

Not suitable for:

• Liquids containing solid particles or fibres
• Flammable liquids
• Mineral oils or synthetic oils (without alternative seal selection)
• 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 DN65 circulators?

This model uses DN65 PN16 DIN flanges with a port-to-port length of 360 mm. Where dimensions match, it can replace other DN65 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 to adjust the previous duty – the pump can be set up or down during commissioning to better match the operating point 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.
