Frequently Asked Questions

What type of pump is this?

This is a Grundfos CM horizontal multistage centrifugal pump. It has an axial suction port, radial discharge port and a close-coupled motor/pump construction mounted on a base plate.

Is this a CM or CME pump?

This is a CM pump, not a CME pump. CM models are fixed-speed pumps with a standard motor. CME models are the variable-speed versions fitted with a Grundfos E-motor / integrated frequency converter.

Is this a single-phase or three-phase pump?

This is a three-phase pump. The motor data lists the supply as 3 × 220–240D / 380–415Y V, 50 Hz. For a typical UK 400–415 V three-phase supply, this would normally be connected in star according to the motor nameplate and site electrical requirements.

What does CM 10-2 mean?

• CM – Grundfos compact horizontal multistage pump range
• 10 – nominal flow size, around 10 m³/h class
• 2 – number of hydraulic stages / impeller stages

What does CM 10-2 A-R-A-V-AQQV F-A-A-N mean?

• CM – Grundfos compact horizontal multistage pump range
• 10 – nominal flow size, around 10 m³/h class
• 2 – number of hydraulic stages / impellers
• A – basic pump version
• R – Rp internal Whitworth pipe thread connection
• A – cast iron material version with stainless steel hydraulic components
• V – FKM rubber components in the pump, excluding the shaft seal code itself
• AQQV – mechanical shaft seal code
• F – 3 × 220–240D / 380–415Y V, 50 Hz motor supply
• A – standard motor configuration
• A – standard connection / motor option suffix for this configuration
• N – no special sensor designation for this fixed-speed CM pump

In plain English, this is a Grundfos CM 10 m³/h class, 2-stage horizontal multistage pump with Rp threaded connections, a cast iron pump body with stainless steel hydraulic components, FKM rubber components, an AQQV mechanical shaft seal, and a 3-phase 400/415V class standard motor.

What connection does this pump have?

This pump has Rp 1 1/2 inch internal threaded suction and discharge connections. It is not supplied as a DIN flanged pump. Please check the existing pipework connection, thread type, installation space and discharge orientation before ordering.

Is this a stainless-steel pump?

No. This is the cast iron CM material version. The pump housing / inlet and discharge parts are cast iron, while the impeller and hydraulic components are stainless steel. If the application requires a stainless-steel pump body throughout, please check whether a CM-I, CM-G, CME-I or CME-G version is required instead.

What does the AQQV shaft seal mean?

The AQQV shaft seal is an unbalanced O-ring type mechanical shaft seal with a fixed seal driver, silicon carbide rotating face, silicon carbide stationary seat and FKM / Viton elastomers.

The final letter is important: V means FKM / Viton elastomers. This differs from an AQQE seal, where the final E would indicate EPDM elastomers.

Why choose an AQQV seal?

The silicon carbide / silicon carbide face pairing is a hard-wearing seal arrangement used where improved wear resistance is required compared with softer carbon-based seal faces. The FKM elastomers can offer better compatibility with some liquids than EPDM, but suitability still depends on the exact liquid, temperature, pressure and concentration.

What liquids can this pump be used with?

This pump is intended for clean, non-aggressive liquids compatible with the cast iron pump housing, stainless steel hydraulic components and AQQV shaft seal. Typical duties include clean water, treated water and suitable process-water applications.

Not suitable for:

• Liquids containing solids or fibres
• Dirty water, wastewater or drainage duties
• Flammable or explosive liquids
• Liquids incompatible with cast iron, stainless steel or FKM elastomers
• Seawater or aggressive saline solutions unless full material compatibility has been confirmed

Can this be used with glycol?

Water-glycol mixtures may be suitable, but the exact glycol type, concentration, inhibitor package, temperature and duty point must be checked. This pump is fitted with an AQQV seal, which uses silicon carbide / silicon carbide seal faces and FKM elastomers.

Glycol can increase liquid density and viscosity, which may reduce hydraulic performance and increase motor load. For glycol duties, the final duty point should be checked against the installed system conditions before ordering.

Does this pump have built-in motor protection?

The product data lists no built-in motor protection. Suitable overload protection and electrical installation should be provided by a qualified electrician in accordance with the motor nameplate and site requirements.

Can this be used as a direct replacement?

It may be suitable as a replacement where the existing pump is a matching Grundfos CM 10-2 with compatible hydraulic duty, connection type, voltage, motor power, seal type and material requirements.

Please compare the existing pump nameplate, electrical supply, pipe connections, dimensions, pressure rating and duty point before ordering. If you are unsure, send us photos of the existing pump and nameplate and we can help check suitability.

Is this a new pump?

This listing is for as new surplus stock. The unit has not been installed or used but may show cosmetic marks from storage and handling.
