Build your own custom K7.


Choose the length of hose, gun and lances to build your very own custom Kranzle K7.


As standard all Kranzle machines are now supplied with D12 Quick Release Guns & Lances.


As part of our custom build option, you can still choose the traditional M22 threaded connection. See build options below.


All hoses are M22 Thread. Quick release applies to the connection between the Lance & the Gun to enable quick interchange of lances (dirtkiller, vario, foam bottle etc.)

If you choose an D12 Quick Release Gun, you will also need a D12 Quick Release connection on all lances and accessories.


A D12 Quick Release Adapter is available to convert traditional M22 threaded accessories to Quick Release.

Designed for Heavy Duty Trade use the K7 is ideal for valeters’ and detailers’  due to its compact size and extremely robust design, an ideal investment due to very low maintenance costs and exceptionally long life expectancy.


Unlike many small units, the K7 is self priming and will happily pull water from a tank and can even lift water from a depth of one metre! Perfect for the mobile valeter or detailer. Plus with the new Easy-Start technology you no longer need to squeeze the trigger gun to fire up your machine.

Standard Machine K7/122 or Auto Shut Off K7/122 TS


What is the difference? The K7/122 Auto Shuff Off / Total Stop (TS) automatically turns off the pump when the trigger on the gun is released (i.e the pump switches on when you hold the trigger gun and spray water and switches off when you release the trigger and aren't spraying water). The K7/122 Standard will run continuously whilst connected to power (this however does not result in a pressure build up, due to the intelligent design of the K7).


K7/122 Standard


The K7/122 Standard machine is more suited to mobile valeters and detailers that are on the move throughout the day and using a generator for power connectivity.


K7/122 Auto Shut Off / Total Stop TS


The K7/122 Auto Shut Off / Total Stop TS is ideal for operators who have the machine fixed in a static position and connected to power for use most of the day. The Auto Shut Off / Total Stop Function will save energy consumption and prolong pump life over extended use when used all day.


The Auto Shut Off / Total Stop TS Version is not ideally suited for use with a generator as the repeated on/off function will cause surges in supply - potentially causing issues with the generator. For generator use Kranzle recommend the standard K7 model.

All Kranzle machines are manufactured with special forged brass housings with a 10 year anti-corrosion guarantee on the pump head, they will not just ‘wear out’ like many domestic pressure washers. Connections are all brass screw fittings sealed by an O-ring making maintenance extremely simple.


To achieve more pressure you can purchase the DirtKiller Lance which is available to buy separately. The DirtKiller is ideal for cleaning stone work and block paving, but a bit too aggressive for car cleaning.


Chemical Injector Kits including Chemical Lance and are also available as an option below.

Kranzle M22 Threaded DirtKiller Lance | 028 Nozzle | 41570-028
The 028 Nozzle is suitable for Kranzle K7 series machines.
Dirtkiller lance's give fantastic results when cleaning stone work and block paving, etc. It is very aggressive, you wouldn't want to use it on your car, the spinning pencil jet combines concentrated power over a larger working area enabling you to clean twice as fast.
Dirtkiller lances and Turbokiller lances work in the same way; the Turbokiller lances are physically larger than the Dirtkiller lances. Do not think that because the Turbo lances cost more they are more powerful - they are not. They are simply bigger, designed for machines pumping out higher volumes of water.
Dirtkillers work well with outputs upto a maximum of 15 ltrs/min. More than 15 ltrs/min output and you need the bigger Turbokiller.
Both types have a floating spinning pencil jet nozzle, impacting all of the available pressure over a very small impact area.
The concentrated spinning jet creates a more powerful ripping force, and rotatating around its central point covers a much bigger area of coverage. Maximum impact pressure over a larger area than previously possible. 
Built by Kranzle with solid brass ends, either protected by plastic, or a rubber casing. Inside is ceramic. While using ceramic is not cheap it is extremely hard wearing, and offers very long life that is unlikely to ever wear-out. Long stainless steel pipe is used for its durability.
