Frequently Asked Questions

What is this pump used for?

This Grundfos TPED 32-200/2 is used for commercial heating, cooling and HVAC circulation duties. It is a twin-head in-line centrifugal pump with electronically controlled motors, designed for clean circulation liquids in building-services systems.

What does TPED mean?

TPED is Grundfos’ electronically controlled twin-head version of the TP dry-rotor in-line pump range. The TP part refers to the in-line dry-rotor pump family, E indicates electronic speed control, and D indicates a twin-head pump arrangement.

What does 32-200/2 mean?

In the Grundfos model code, 32 refers to the DN32 inlet and outlet size. 200 is the maximum head reference in decimetres, equal to approximately 20 metres. The /2 indicates a 2-pole motor speed version.

What does A-F-A-BQQE-GWB mean?

• A – basic pump version
• F – DIN flanged pipe connection
• A – standard cast-iron material version
• BQQE – mechanical shaft seal code
• GWB – motor / power / manufacturer variant suffix

Is this a 230V pump?

No. Product number 98512486 is listed as a 3-phase 3 × 380–500V, 50Hz TPED pump. It should be treated as a 400V / 415V class commercial pump, not a standard 230V single-phase circulator.

What is the BQQE shaft seal?

BQQE is the Grundfos shaft seal code. It indicates a rubber bellows mechanical shaft seal with silicon carbide / silicon carbide seal faces and EPDM elastomers.

This seal is a strong choice for clean heating and cooling water circulation duties. Silicon carbide / silicon carbide seal faces offer good wear resistance and are commonly used where clean water, hot water or compatible treated water is being circulated.

What temperature range can this pump operate at?

For TP / TPE / TPED pumps fitted with a BQQE seal, Grundfos lists a liquid temperature range of -25°C to +120°C. Actual suitability still depends on the pumped liquid, system pressure, water quality, glycol concentration, additives and installation conditions.

What liquids is this pump suitable for?

This pump is suitable for thin, clean, non-aggressive and non-flammable liquids that do not contain solid particles or fibres which could attack the pump mechanically or chemically.

Typical suitable duties include:

• Clean heating system water
• Clean cooling water
• Chilled-water circulation
• Air-conditioning circulation water
• District heating and cooling water
• Softened water, subject to water quality and system conditions
• Compatible clean industrial circulation liquids

Can this pump be used with glycol?

Yes, subject to the exact mixture and operating conditions. Grundfos states that where glycol or another antifreeze agent is added to the pumped liquid, the pump must have a BQQE or DQQE shaft seal. This pump is fitted with BQQE.

Glycol concentration, viscosity, liquid temperature and inhibitor package can affect pump performance, pressure loss and motor load, so the final duty should be checked before use.

Can this pump handle dirty water or wastewater?

No. This is a clean-water circulation pump. It is not designed for dirty water, sewage, wastewater, sludge, solids, fibres or drainage applications.

Is this a complete twin-head pump?

Yes. This listing is for a complete TPED twin-head pump assembly, not just a replacement head. The pump has two electronically controlled motor/pump heads mounted on a common in-line pump body.

Can both pump heads run at the same time?

How the two heads operate depends on the control setup. Twin-head pumps are commonly used for duty/standby or alternating operation, and may be configured through the site controls or the pump’s electronic control settings. The correct operating mode should be set during commissioning.

Does this need commissioning?

Yes. This is an electronically controlled TPED pump, so the control mode, setpoint, operating limits and any external control/BMS integration should be checked during installation. It may be commissioned using suitable Grundfos tools and site controls depending on the installation.

Why is this being sold as as-new if it has run for two hours?

This pump was briefly fitted and commissioned, then removed after approximately two hours because it was the wrong size for the installation. It has not been used as a long-term working pump. We are listing it transparently as as-new surplus stock with brief commissioning use, and supplying it with a 2-year guarantee.

Will this replace my existing DN32 TPED pump?

It may be suitable if your existing pump is a matching DN32 flanged TPED / TPE style installation. Before ordering, please check the product number, flange size, port-to-port length, voltage, control arrangement and duty point.

What should I check before ordering?

• Existing pump model and product number
• DN32 flange size and flange standard
• Port-to-port length
• Electrical supply: 3-phase 3 × 380–500V / 400V / 415V class
• Control method and BMS requirements
• Required duty point: flow and head
• Pumped liquid, temperature and glycol concentration if applicable
