Heavy duty high pressure cleaning equipment for industrial sites, workshops, factories and other high demand environments – machines specified for long shifts, repeated cycles and high frequency work.
Supplied on 230V single phase through to 525V for underground mining, and in service across agriculture, food and beverage manufacturing, automotive, transport, mining, construction, municipalities and contract cleaning.
Choosing between the three ranges
Cold water does most commercial work – vehicles, plant, buildings, yards and workshops. Hot water is chosen where the soiling is oily or greasy: heat dissolves oils, so the chemical is used sparingly at the end rather than doing the whole job. Petrol and diesel are for sites with no electrical supply, or none suitable for a machine of the size required.

What makes a Kränzle pump last in industrial service
Forged special-brass pump head
The heart of every machine is a pump head forged from special brass rather than cast. Brass resists corrosion, and both the long-established axial pump and the in-line RP pump run low-wear components - which is what gives the pump its service life.
Ceramic-coated stainless steel plungers
Stainless steel conducts heat away from the seal; the hard ceramic coating gives an extremely low-wear working surface. The two together are what slow the wear at the water seals, and the seals are what decide when a pump needs rebuilding.
Slow-running 1,400 r.p.m motor
The machines built for continuous operation use a four-pole electric motor turning at 1,400 r.p.m rather than 2,800. The lower speed reduces the starting current and, more importantly, halves the work the pump does for the same output - which is where the saving on wear and maintenance comes from. It also runs quieter.
Dry-run safety
Each plunger carries a fabric sleeve and a Teflon graphite backing ring, which lubricate and hold the temperature down inside the pump. A water cushion between the high pressure seals stops any air that is drawn in from reaching the pump chamber, so the pump tolerates a period without water.
Total-Stop and safety shutdown
Closing the trigger gun switches the motor off automatically, which relieves the pump and drive, cuts the noise and reduces power consumption. If a machine is left switched on but unused, it deactivates itself after approximately 20 minutes.
Built, stocked and serviced in Cape Town
The stainless steel frames, cabinets, wall-mounted installations and custom systems these pumps are supplied in are manufactured at our own facility, so a machine can be built to the application rather than chosen from a catalogue. Spares, servicing, repairs and operator training run from the same place.
The water tank and low level cut-out
Water starvation is the leading cause of high pressure cleaner damage across all brands. Where the pump is not supplied with enough water it draws air on the compression stroke, which causes cavitation, loss of pressure and premature damage to the seals and valves. The available supply should be measured into a container for one minute rather than judged by the size of the tap, and should be approximately one third more than the rated output of the pump: a 10 L/min pump wants roughly 13.5 L/min at the machine.
The Kränzle Carwash, Core, Quadro and Electra machines all carry a water tank with a low level cut-out, as do the locally built stainless steel cabinet and wall-mounted systems. A float valve controls the incoming water, so the pump draws from a buffer rather than off a line that may surge or drop away, and the cut-out stops the machine rather than letting it run dry. The compact Kränzle HD and K 2000 machines are fed directly and carry no tank.
German-built pumps in locally built stainless steel
The Kränzle high pressure cleaners in this range are built in Bavaria by a German manufacturer that has made high pressure cleaners for over 50 years. Kränzle South Africa has supplied them here since 1989.
Machines are supplied nationally through direct sales and our dealer network, and are backed by technical service, spare parts, repairs and operator training. Specifications for each range are on its own page - cold water, hot water and petrol and diesel.
Frequently asked questions
What is the difference between a commercial and a domestic pressure washer?
Commercial and industrial machines use bigger motors and components. The professional range runs four-pole motors at 1,400 r.p.m, against 2,800 r.p.m on domestic and compact machines. At half the speed the pump valves complete half the cycles per hour, which is why the professional machines are the ones rated for continuous use. Any electric high pressure washer running at 2,800 r.p.m is not recommended for extended continuous operation.
Should a machine be chosen on pressure or on water flow?
Both, and separately. Pressure determines the impact force that breaks the bond between the dirt and the surface. Water flow determines how quickly the loosened contamination is flushed away. A machine rated 200 bar at 4 L/min and one rated 100 bar at 13 L/min suit different work. Where the soiling is bonded, take the pressure; where it is bulk, take the flow.
When is a hot water high pressure cleaner necessary?
Where the soiling is oily or greasy. Heat dissolves oils, so hot water removes the majority of that soiling before any chemical is applied. Without hot water the same result requires chemical to do the whole job. Hot water machines are supplied electrically heated or with a diesel burner coil.
What electrical supply do these machines need?
Single-phase 230V for the smaller machines, 400V three-phase from approximately 12 L/min upward, and 525V for underground mining applications. A 525V machine is a special-order build – the motor is specially wound for it, which adds cost and lead time. Confirm voltage, phase, available amperage and plug type before quoting.
What water supply does a high pressure cleaner need?
Approximately one third more than the pump’s rated output. A 10 L/min pump needs roughly 13.5 L/min available at the machine. Measure the supply into a container for one minute rather than judging it by the tap size. Water starvation is the leading cause of high pressure cleaner damage across all brands.
What do TS and TST mean on a Kränzle model number?
TS is a Total-Stop model, where closing the trigger gun stops the motor. TST is the same machine with an integrated hose reel. D12 indicates the professional quick-release coupling system, as against D10 on the private-user range.
Where can these machines be bought in South Africa?
Directly from Kränzle South Africa in Cape Town, or through our national dealer network. Enquiries from anywhere in South Africa and neighbouring countries are handled centrally and either quoted directly or routed to the dealer for that region.
