If you look at the Kranzle brand, you will see sophisticated high-pressure cleaners with technical benefits that are designed to extend the service life of the machine. Many of these techncal details are innovations that original in the Kranzle development center in Illertissen Germany and are exclusive to Kranzle machines. A properly designed pressure washer has a brass pump head, a 4 pole (slow revving) electric motor, continously adjustable pressure and of course a decent a warranty, So we’ll just explain the key features that are unique to Kranzle and why it’s important to know these things.
The kranzle pump head is manufactured by Kranzle in Germany from forged special brass and guarantees an extremely long service life, in fact it come with a 10 YEAR GUARANTEE!
All kranzle pump have ceramic coated stainless steel plungers. These provide excellent thermal conductivity and when combined with the positive characteristics of a hard ceramic coating, offer an extremely low-wear surface.
Kranzle pumps can be run without water for quite some period without suffering any damage. This is called the ‘Dry-run-safety’ and is achieved by creating a water cushion between the high-pressure seals on the plungers which prevents any sucked in air from reaching the pump chamber.
Each plunger is equipped with a fabric sleeve and a Teflon graphite backing ring. the excellent Iubricating properties of Teflon graphite serve to reduce both the friction and temperature inside the pump.
