Kamco Clearflow CF40 Evolution — 39L translucent HDPE tank | 0.80 kW / 230V motor | Up to 25 radiators (2–3 storeys) | The class-leading domestic professional power flushing pump
The Kamco Clearflow CF40 Evolution is the most popular professional power flushing pump in the UK, trusted by heating engineers for over three decades. With a 0.80 kW motor delivering up to 90 litres per minute, the CF40 clears even the most heavily sludged domestic systems in a single visit — without the need for disruptive pre-treatment.
Kamco pioneered power flushing in 1992, and the CF40 reflects everything learned since: an instantaneous flow reverser to dislodge debris from both directions, acid-proof construction for dual-purpose descaling capability, a large translucent 39L HDPE tank for chemical visibility, and 75mm wheels plus an integral handle for easy manoeuvring between jobs.
In the 60% of the UK with hard water, the CF40's acid-resistant materials allow it to also descale boilers, water heaters and heat exchangers using Kamco's Scalebreaker range — giving engineers two tools in one.
🎓 Free Proficiency Training Included — Every Clearflow purchase includes a free session at Kamco's UK Training Academy, St Albans. Includes a 10-piece BSP adapter set for connection to virtually any UK heating system.
Key Features
Instantaneous Flow ReverserSingle lever reverses circulation direction immediately — disturbs and mobilises stubborn blockages without disconnecting hoses or waiting.
High-Flow 0.80 kW MotorDelivers up to 90 L/min flow rate, generating the turbulent velocity needed to lift and suspend heavy corrosion sludge throughout the system.
Acid-Proof ConstructionAll wetted parts resist commercial acids and alkalis — enabling descaling of boilers, calorifiers and heat exchangers with Scalebreaker chemicals.
39L Translucent HDPE TankLarge tank reduces refilling stops mid-flush. Translucent material gives a clear view of chemical colour and water clarity during flushing.
3-Port Combination ValveCombines isolation and dump functions in one valve, simplifying the flushing sequence and reducing the risk of accidental flooding.
IP55 Motor RatingProtected against ingress of dust and water jets, ensuring reliable operation in the demanding on-site environments that heating engineers work in.
75mm Wheels & HandleCompact transport solution — wheels under the base and integral handle allow easy movement in hallways and up stairs without lifting assistance.
Run Dry CapabilityMotor tolerates brief operation without liquid, protecting against accidental damage when the tank empties during final dump-down.
10-Piece BSP Adapter SetComprehensive set of BSP adapters included, enabling connection to virtually all UK domestic circulator pump configurations.
Waterproof Hose CaddyRobust waterproof carry crate keeps hoses organised, clean and protected between jobs — a professional touch appreciated by repeat customers.
Operation to 75°CHot-water flushing mode activates the heating system to mobilise temperature-sensitive deposits more effectively than cold flushing alone.
2-Year Parts & Labour WarrantyFull manufacturer warranty with Kamco's dedicated service workshop and technical helpline for ongoing support throughout the pump's life.

Frequently Asked Questions
CF40 vs CF90 — which should I buy?The CF40 handles domestic systems up to 25 radiators over 2–3 storeys. If you regularly work on larger domestic or small commercial properties (up to 40 radiators, 3 storeys), the CF90 is a better fit. The CF90 has a 57L tank, 150 L/min flow rate and 200 mm wheels. For most domestic heating engineers, the CF40 is the optimal balance of performance and portability.
What chemicals should I use with the CF40?Kamco Power Flush FX2 is the recommended one-shot flushing chemical for steel/copper/plastic systems. For aluminium radiators or heat exchangers, use HyperFlush instead. Always follow with a DWTA-approved corrosion inhibitor such as SystemSafe DM. FX2 must be neutralised before disposal using Kamco Neutralising Crystals.
Can I connect the CF40 to a combi boiler?Yes. The most common connection method for combi boilers is to connect the CF40 across the system pump ports (removing the pump) or across the boiler flow and return after isolating the boiler. The included BSP adapter set covers the most common UK boiler and pump configurations.
Is free training really included?Yes — every Clearflow purchase includes one free proficiency training place at Kamco's St Albans Training Centre. Kamco also offers a Weblink scheme that lists Clearflow-trained engineers on their public directory, which can generate new business from homeowners searching for local power flushing services.
Can I use the CF40 for descaling?Yes. The acid-proof construction means the CF40 can circulate Kamco Scalebreaker descaling chemicals to remove limescale from boilers, water heaters, calorifiers and heat exchangers — making it a dual-purpose tool worth investing in for hard water areas.
