Frequently Asked Questions

What is this pump used for?

This Grundfos TPD 100-160/2 is used for commercial heating, cooling and HVAC circulation duties. It is an in-line centrifugal twin-head pump, designed for moving clean circulation liquids around closed-loop building services systems.

What does TPD mean?

TPD is Grundfos’ twin-head dry-rotor in-line pump range. A TPD pump has two pump heads mounted on one common pump body, allowing the system to run one head at a time, alternate between heads, or use the second head as standby depending on the installed controls.

What does 100-160/2 mean?

In the Grundfos model code, 100 refers to the nominal DN100 inlet and outlet connection size. 160 refers to the nominal maximum head class of approximately 16 metres. The /2 indicates a 2-pole motor speed version.

What does A-F-A-BQQE-KW1 mean?

• A – basic pump version
• F – DIN flanged pipe connection
• A – standard cast-iron material version
• BQQE – mechanical shaft seal code
• KW1 – motor / voltage / speed variant suffix

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 is a common seal choice for clean heating and cooling water duties where the liquid is compatible with EPDM.

What temperature range can this pump operate at?

For this TPD 100-160/2 A-F-A-BQQE-KW1 version, the fitted BQQE shaft seal has a listed liquid temperature range of -25°C to +120°C.

The wider TP Series 300 PN16 pump range may be available with alternative shaft seals for higher-temperature duties, but this exact pump is fitted with BQQE, so -25°C to +120°C is the suitable temperature range to use for this listing.

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.

For this BQQE version, suitable liquid examples include:

• Central heating system water – water quality must meet accepted heating-system standards
• District-heating water – up to 120°C with the fitted BQQE seal
• Cooling water / chilled-water circuits
• Hot tap water / domestic hot-water circulation, subject to system design and material suitability
• Boiler-feed water – up to 120°C with BQQE, subject to water quality
• Condensate – up to 120°C with BQQE
• Softened water – up to 120°C with BQQE; oxygen-free conditions may be required depending on duty
• Clean industrial circulation liquids compatible with cast iron, EPDM and silicon carbide / silicon carbide seal faces

Can this pump be used with glycol or antifreeze mixtures?

Yes, subject to the exact mixture and operating conditions. Grundfos states that if 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.

Suitable coolant / antifreeze examples listed for BQQE include:

• Ethylene glycol mixtures – up to 120°C, subject to concentration, viscosity and system design
• Propylene glycol mixtures – up to 120°C, subject to concentration, viscosity and system design
• Glycerine / glycerol mixtures – up to 120°C, subject to concentration and viscosity
• Potassium acetate brines – up to 120°C in standard guidance, with some conditions listed separately up to 110°C
• Potassium formate brines – up to 120°C, subject to concentration and system design
• Sodium chloride brine – listed at up to 30% and below 5°C, subject to corrosion risk and system design

Glycol and brine mixtures can have higher density and viscosity than water. This can reduce hydraulic performance, increase pressure loss and increase motor load, so the final duty should be checked before use.

What treated-water or chemical duties are listed for BQQE?

Grundfos lists a number of treated-water and chemical duties where BQQE is shown as the selected shaft seal for TP Series 300 PN16 applications. These should be treated as guidance only, because concentration, temperature, pressure, water quality and additives all affect compatibility.

• Hydrogen peroxide – below 40°C and below 2%
• Ammonium bicarbonate – below 20°C and below 15%
• Calcium acetate – below 20°C and below 30%
• Potassium bicarbonate – below 20°C and below 20%
• Potassium carbonate – below 20°C and below 20%
• Potassium permanganate – below 20°C and below 10%
• Potassium sulphate – below 20°C and below 20%
• Sodium acetate – below 20°C and below 100%
• Sodium bicarbonate – below 20°C and below 2%
• Sodium carbonate – below 20°C and below 20%
• Sodium nitrate – below 0°C and below 40%
• Sodium nitrite – below 20°C and below 40%
• Disodium phosphate – below 100°C and below 30%
• Trisodium phosphate – below 90°C and below 20%
• Sodium sulphate – below 20°C and below 20%
• Sodium sulphite – below 20°C and below 1%
• Ammonium hydroxide – below 100°C and below 30%
• Calcium hydroxide – below 100°C and below 10%
• Potassium hydroxide – below 20°C and below 20%
• Sodium hydroxide – below 40°C and below 20%

What liquids should this pump not be used for?

• Dirty water, wastewater, sewage, sludge, solids or fibres
• Flammable liquids
• Liquids that chemically attack cast iron, EPDM or the BQQE shaft seal materials
• Mineral oils, synthetic oils, vegetable oils and fuel-related liquids unless the seal and elastomers are specifically reviewed and changed if required
• Seawater or aggressive saline duties unless the full material selection is confirmed as suitable

Is this suitable for potable water?

This is a cast-iron commercial circulator and is not normally selected for potable domestic hot-water duties. For potable or domestic hot-water applications, pump material, water quality, temperature, system design and local regulations must be checked carefully. Stainless-steel or bronze versions are usually preferred where potable-water compatibility is required.

Is this a variable-speed pump?

No. This is a fixed-speed TPD pump, not a TPE or TPED electronically controlled version. Any duty/standby or alternating operation would normally be handled by the external control panel or BMS arrangement on site.

Can both pump heads run at the same time?

The pump body contains two pump heads, but how they operate depends on the system controls. In many installations, twin-head pumps are used for duty/standby or automatic alternation, with one head running while the other remains available as backup. Some systems may use both heads depending on the control arrangement, but this should be checked against the site design.

Will this replace my existing DN100 TPD pump?

This pump has DN100 DIN flanged connections, PN16 pressure rating and a 500 mm port-to-port length. It may be a suitable replacement for existing matching Grundfos TPD 100-160/2 installations, but the product number, flange standard, port-to-port length, voltage, motor power and duty point should be checked before ordering.

What electrical supply does it need?

This pump is a 3-phase 50 Hz unit with a 3 × 380–415V Delta motor configuration. Electrical installation should be carried out by a qualified person using suitable overload protection and control gear.

Does this pump need a control panel?

The pump itself is fixed speed. Twin-head operation, duty/standby changeover, overload protection and any BMS integration are normally handled by the external control panel or site controls. The motor protection thermistors should be connected to suitable protection equipment where required.
