The Story

The Kamco Clearflow CF40 Evolution is a compact 230V power flushing pump built to clean domestic central heating systems of up to 25 radiators, spanning 2–3 storeys, including underfloor heating systems. Water is circulated through the system at high velocity to dislodge black magnetite sludge, corrosion debris and scale in line with BS7593:2006, restoring flow and heat transfer across the system before a new boiler or components are fitted, or as remedial maintenance on an existing installation.

An instantaneous flow direction reverser lets the engineer alternate flow through each radiator without disconnecting hoses, so every part of the system is scoured with turbulent water — improving cleansing efficiency and cutting job time. The pump is supplied as a complete start kit: hoses, couplings, BSP adapters, a starter pack of flushing chemicals and a waterproof hose caddy are all included, so engineers can begin flushing straight from the box.

Complete Start Kit Included
Every CF40 Evolution ships with a starter pack of flushing chemicals, a 10-piece BSP adapter set, hoses, couplings and fittings, a waterproof hose caddy, and a full operating manual — ready to flush the moment it arrives on site.
Power & Water Supply
The CF40 Evolution runs from a standard 230V supply and requires a mains water connection to refill the tank during flushing. A 110V site version is also available from Kamco for sites requiring reduced voltage equipment.
Instant Flow Direction Reverser
Combined isolating and dump valves mean a single twist of one handle switches the pump into dumping mode, so the whole system can be scoured with high-velocity turbulent water from both directions without re-plumbing hoses.
Acid-Resistant Construction
Built from corrosion-resistant materials throughout, the CF40 Evolution doubles as a descaling pump for domestic boilers, water heaters and heat exchangers — useful across the roughly 60% of the UK with a hard water supply.
Large 39L Translucent Tank
The 39 litre HDPE tank is translucent for at-a-glance level checks and sized to minimise overflow risk during flushing, while still keeping the unit compact enough for van storage.
75mm Wheels & Integral Handle
Fitted with 75mm wheels and a carry handle, the Evolution can be wheeled or carried around site even when the tank is full, making it practical to move between properties or up to first-floor systems.
High-Flow 0.8kW Motor
The 0.8kW, IP55-rated motor delivers flow rates up to 90 l/min and a maximum head of 20m — enough turbulence to maximise removal of sludge and corrosion debris from typical domestic systems.
2-Year Parts & Labour Warranty
Every CF40 Evolution is backed by a 2-year parts and labour warranty, plus a free proficiency training session and ongoing telephone support from Kamco's helpline and service workshop.

Frequently Asked Questions
How many radiators can the CF40 Evolution handle?
It is rated for domestic heating systems of up to 20–25 radiators across 2–3 storeys. Larger systems can still be flushed if they are suitably sectioned into smaller loops.
Can the CF40 be used for descaling as well as power flushing?
Yes. Its acid-resistant construction makes it a dual-purpose pump, suitable for descaling domestic boilers, water heaters and heat exchangers using commercially available acids, alkaline solutions or chlorine solutions.
Does it come with everything needed to start flushing straight away?
Yes — the start kit includes hoses, couplings, a 10-piece BSP adapter set, a starter pack of chemicals sufficient for two flushes, a waterproof hose caddy and the full operating manual.
What power supply does it need?
The standard CF40 Evolution runs from a 230V mains supply. A 110V site-safe version is also available from Kamco for sites requiring reduced voltage tools.
How is the flow direction reversed during a flush?
The CF40 Evolution uses an instantaneous flow reverser — combined isolating and dump valves that switch the pump into dumping mode with a single twist of one handle, without needing to disconnect or swap hoses.
Is training provided?
Yes. Kamco includes a free proficiency training session at their St Albans training centre with every Clearflow pump, plus ongoing telephone helpline support.
