Cold Water High Pressure Cleaners | Kränzle South Africa

The Kränzle cold water range consists of commercial and industrial high pressure washers, which are different to the domestic range as they make use of bigger motors and components. They run at 1,400 r.p.m and are built for continuous use. Any electric high pressure washer with a motor speed of 2,800 r.p.m is not recommended for extended periods of use.

Each machine is supplied ready to work, with a Starlet gun, high pressure hose and lance as standard. A range of further lances and nozzles, including the Dirtkiller for concentrated impact, is available to suit the work.

The pump

The heart of every high pressure cleaner is the high pressure pump. Kränzle pump heads are machined from forged special brass, with ceramic-coated stainless steel pistons. Brass resists corrosion and the ceramic working surface reduces wear at the water seals, which is what determines service life in daily use.

It is the same pump whichever format the machine is supplied in. A mobile unit, a machine on a frame, and one built into a locally manufactured stainless steel cabinet all run the same German Kränzle pump – only the housing around it changes.

The quality of the components in the pump head, as well as the safety features that protect the pump, is what determines how long a machine lasts. It is on this that Kränzle guarantees users the highest quality, superior cleaning power and a particularly long service life.

Frequently asked questions

What makes a cold water high pressure cleaner suitable for continuous use?

The motor speed. Commercial and industrial machines use a four-pole motor running at 1,400 r.p.m, against 2,800 r.p.m on domestic and compact machines. At 1,400 r.p.m the pump valves complete approximately 84,000 opening and closing cycles per hour, against approximately 168,000 at 2,800 r.p.m. Any electric high pressure washer with a motor speed of 2,800 r.p.m is not recommended for extended continuous use.

What voltages are these machines available in?

230V single-phase on machines up to approximately 11 L/min, 400V three-phase above that, and 525V for underground mining. A 525V machine is a special-order build, as the motor must be specially wound for it, which adds cost and lead time.

Which machines carry a water tank, and what does it do?

It buffers fluctuations in the incoming supply, with a float valve controlling the inflow, 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 Kränzle Carwash, Core and Quadro machines carry one, as do the locally built stainless steel cabinet and wall-mounted systems. The compact Kränzle HD and K 2000 machines are fed directly and carry no tank. Water starvation is the leading cause of high pressure cleaner damage across all brands.

Can a cold water machine be wall mounted?

Yes. The same pump and motor platforms are supplied in locally manufactured stainless steel cabinets or on open-style frames. A wall mounted installation can include a break tank and float valve, a low level cut-out, an electrical control panel, remote hose reels or a swivel boom, and chemical or foam injection. Centralised systems serve several wash points from one machine.

Can the machine draw water from a tank rather than a tap?

Most 1,400 r.p.m models can draw from a clean external container or reservoir through an approved suction hose and filter, at a typical lift of 1.5 m or 2.5 m depending on model. Suction performance depends on airtight connections, priming, a clean filter, hose size and vertical lift.

What water supply is required?

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.
