Commercial & Industrial Kerrick Pressure Washers

Q: What is the difference between Direct Drive and Gearbox Driven pressure washers?

This is a critical distinction for commercial operators:Direct Drive: The pump is connected directly to the engine shaft, spinning at roughly 3400 RPM. These are lighter and cheaper but generate more heat and vibration, ideal for intermittent use.Gearbox Driven: A gearbox reduces the pump speed to roughly 1450 RPM. This drastically cuts friction and heat, allowing the Kerrick machine to run continuously for 8+ hour shifts without destroying the pump.

Q: What is a turbo nozzle, and when should I use it?

A turbo nozzle takes a highly concentrated 0-degree pinpoint jet and spins it in a rapid circular motion (up to 3000 RPM). It delivers the aggressive cutting power of a straight jet with the wider coverage of a fan spray. It is perfect for stripping moss from concrete, but should never be used on car paint or soft timber, as it will gouge the surface.

When you are tasked with blasting hardened concrete off scaffolding, stripping oxidation from heavy earthmoving equipment, or maintaining a massive agricultural fleet, standard domestic water blasters simply cannot survive the workload. Kerrick Pressure Washers are built without compromise. Recognized across Australia as the heavy-duty standard for industrial cleaning, Kerrick machines deliver relentless PSI and massive water flow to strip away the toughest industrial contaminants in record time.

At Freshway Supplies, we are a leading B2B distributor of the complete Kerrick pressure washing range. Our inventory is tailored for professional contractors, offering heavy-duty Electric Washers for stationary wash-bays, alongside rugged Petrol and Diesel Washers mounted on heavy-duty steel roll-frames for complete off-grid independence on remote civil worksites.

Stop losing money to equipment failure and underpowered pumps. Upgrade your cleaning fleet with Kerrick’s industrial-grade Italian brass pumps and low-speed motors designed for continuous, all-day operation. Enjoy highly competitive wholesale trade pricing, expert technical matching, and fast, secure heavy-freight delivery right across Australia.

The Kerrick Industrial Advantage

Premium Italian Pumps: Kerrick machines utilize world-class forged brass pump heads with ceramic plungers, ensuring extreme durability and resistance to wear, heat, and corrosion.
Low-Speed Motors & Gearboxes: Many models feature heavy-duty gearboxes that reduce pump speed (often down to 1450 RPM). This drastically reduces friction, heat, and wear during continuous 8-hour shifts.
Rugged Roll-Frames: Built for brutal worksites, Kerrick petrol and diesel models are encased in heavy-gauge, powder-coated steel roll frames with puncture-proof pneumatic tires.
Massive Flow Rates: Kerrick prioritizes high Litres Per Minute (LPM) alongside extreme PSI, giving operators the heavy 'flushing' action needed to rapidly clear thick mud and slurry.

Frequently Asked Questions

What is the difference between Direct Drive and Gearbox Driven pressure washers?

This is a critical distinction for commercial operators:

Direct Drive: The pump is connected directly to the engine shaft, spinning at roughly 3400 RPM. These are lighter and cheaper but generate more heat and vibration, ideal for intermittent use.
Gearbox Driven: A gearbox reduces the pump speed to roughly 1450 RPM. This drastically cuts friction and heat, allowing the Kerrick machine to run continuously for 8+ hour shifts without destroying the pump.

Should I choose a petrol or electric Kerrick pressure washer?

If you are cleaning indoor wash-bays, food processing areas, or workshops with accessible power, an Electric Washer produces zero exhaust fumes and is significantly quieter. If you are working on remote construction sites, farms, or doing mobile municipal cleaning, a Petrol/Diesel Washer provides the ultimate off-grid power and mobility.

Why are ceramic plungers important in Kerrick pumps?

Standard pressure washers often use stainless steel plungers that easily scratch when exposed to grit. Premium Kerrick machines utilize solid ceramic plungers (or heavy ceramic coatings). Ceramic has exceptional thermal conductivity and extreme resistance to friction and hard water minerals, massively extending the lifespan of the high-pressure seals.

What does the Unloader Valve do on my pressure washer?

The unloader valve is a critical safety component. When you release the trigger on the spray gun, the engine and pump keep running. The unloader valve safely redirects the high-pressure water back into the pump inlet (bypass mode). However, you should never leave a machine in bypass for more than 3 to 5 minutes, as the trapped water will rapidly boil and melt the internal pump seals.

Can a Kerrick petrol machine draw water from an unpressurized tank?

Yes. Most heavy-duty Kerrick machines feature high-quality pumps with excellent suction capabilities, allowing them to draw water from an IBC tank or water bowser. You must use a rigid, reinforced suction hose with an integrated heavy-duty water filter to prevent the hose from collapsing or sucking debris into the ceramic pump.

Why would I need a Hot Water Kerrick pressure washer?

Cold water is excellent for blasting away mud and dirt, but it cannot dissolve thick oils. A Hot Water machine utilizes a diesel burner to superheat the water (often up to 150°C steam). This extreme thermal energy instantly melts heavy engine grease, hydraulic fluid, and animal fats, making it absolutely essential for automotive workshops and abattoirs.

What is a turbo nozzle, and when should I use it?

A turbo nozzle takes a highly concentrated 0-degree pinpoint jet and spins it in a rapid circular motion (up to 3000 RPM). It delivers the aggressive cutting power of a straight jet with the wider coverage of a fan spray. It is perfect for stripping moss from concrete, but should never be used on car paint or soft timber, as it will gouge the surface.

How often should I change the pump oil in a commercial pressure washer?

To ensure maximum commercial longevity, the oil in your Kerrick high-pressure pump must be changed after the initial 50 hours of operation (the break-in period). Following that, you should drain and replace the pump oil every 500 operating hours or at least once every 12 months.

Can I extend the high-pressure hose on my Kerrick machine?

Yes. You can easily extend your reach by connecting heavy-duty, steel-braided hose extensions using 3/8-inch Quick Connect couplers. However, avoid extending your total hose length beyond 30 to 50 metres, as the internal friction will cause a noticeable drop in pressure at the spray nozzle.

Do you supply non-marking hoses for indoor commercial cleaning?

Yes. Standard black high-pressure hoses can leave stubborn rubber scuff marks when dragged across light-colored indoor tiles or polished concrete floors. We supply premium Blue or Grey Non-Marking Hoses, perfectly suited for food processing facilities, hospitals, and indoor commercial washdowns.
