Kamco SystemSafe KS8 Hyperflush is a non-acidic powerflushing cleaner formulated to mobilise and disperse sludge, limescale, rust and general corrosion debris from central heating systems. Unlike acid-based one-shot flushing chemicals, KS8 is gentle enough for aluminium components, making it the correct choice on systems that combine aluminium radiators, aluminium boiler heat exchangers, or other mixed-metal circuits where acidic flushes are unsuitable.
Designed for use with a Kamco Clearflow powerflushing pump for a full system deep clean, KS8 can also be dosed through the system circulator pump and left to work as a pre-treatment for up to 7 days before flushing on particularly stubborn systems. This dual application method gives installers flexibility on site, whether carrying out a same-visit powerflush or setting up a system for a scheduled flush.

Good to Know
KS8 Hyperflush is suitable for all metals including aluminium, unlike acid-based one-shot flushes such as Kamco FX2. Where a system contains an aluminium heat exchanger or aluminium radiators, KS8 should be used in place of an acidic flushing chemical.
Key Features
Non-Acidic Formula
Breaks down sludge, limescale, rust and corrosion deposits without the acidic action of one-shot flushing liquids.
Safe for Aluminium
Suitable for all metals including aluminium, making it compatible with mixed-metal and modern low-mass heat exchanger systems.
Powerflushing or Pre-Treatment
Use with a Kamco power flushing pump for an immediate deep clean, or dose via the system circulator pump and leave to work for up to 7 days before flushing.
Restores System Efficiency
Clears built-up debris that restricts flow and heat transfer, helping resolve cold radiators, noisy boilers and reduced efficiency.
Odourless Liquid
A colourless-to-pale-yellow, odourless liquid that is straightforward to handle and dose on site.
Suitable for New and Old Systems
Formulated for use across a wide range of system ages and configurations, both new installations and older heating systems.
Important Safety Information
KS8 carries hazard classifications H315 (causes skin irritation) and H319 (causes serious eye irritation). Wear protective gloves and eye protection when handling, and avoid direct skin or eye contact with the undiluted product.

Frequently Asked Questions
Can KS8 Hyperflush be used on aluminium radiators or boilers?▼
Yes. KS8 is specifically formulated to be suitable for all metals including aluminium, unlike acid-based one-shot flushing liquids which are not recommended for aluminium components.
Do I need a powerflushing pump to use KS8?▼
Not necessarily. Best results come from using a Kamco power flushing pump for a full deep clean, but KS8 can also be circulated using the system's own circulator pump as a pre-treatment before a separate flushing visit.
How long can KS8 be left in the system before flushing?▼
KS8 can be used as a pre-treatment for up to 7 days prior to a flushing process, allowing it time to mobilise stubborn sludge and scale deposits ahead of the flush.
What size bottles are available?▼
Kamco SystemSafe KS8 Hyperflush is available in 500ml (BHF003), 2.5L (BHF007) and 10L (BHF005) pack sizes to suit both single-system doses and trade-volume use.
Is KS8 acidic like Kamco FX2?▼
No. KS8 is a non-acidic formulation, which is why it is compatible with aluminium and mixed-metal systems where acid-based flushes such as FX2 are not recommended.
