SIP TEMPEST P660/150 Electric Pressure Washer

Italian-Built Commercial Pressure Washing Performance — Engineered to Last Twice as Long

Introducing the SIP TEMPEST P660/150 Electric Pressure Washer — a premium, Italian-manufactured commercial cleaning machine built around heavy-duty components that set it apart from the competition at every level. With a 2.9kW brushless induction motor, a corrosion-resistant brass-headed Triplex crankshaft pump, 150bar maximum pressure, and an impressive 660L/hr flow rate, the P660/150 is engineered for demanding commercial applications where reliability, longevity, and sustained performance are non-negotiable.

Why the SIP TEMPEST P660/150 Is in a Class of Its Own

Most pressure washers at this power level use brush motors and standard pump configurations that degrade over time under heavy use. The P660/150 takes a fundamentally different approach — combining a 4-pole low-rotation brushless induction motor with a brass-headed in-line Triplex crankshaft pump to deliver a machine that SIP rates at double the lifespan of comparable alternatives. For commercial users who depend on their equipment day in and day out, this is not a marginal improvement — it is a significant long-term investment advantage.

Key Features & Benefits

2.9kW 4-Pole Brushless Induction Motor — Built for Commercial Endurance

The heart of the P660/150 is its 2.9kW (3.9hp) 4-pole low-rotation brushless induction motor, running at just 1450rpm. This lower rotational speed is a key engineering advantage — generating less heat, less friction, and less wear over sustained operating periods compared to higher-speed brush motors. Brushless induction motors have no brushes to replace, run significantly cooler under load, and are the motor technology of choice in professional industrial machinery worldwide. The result is a motor built not just for today's job, but for years of reliable commercial service.

Brass-Headed In-Line Triplex Crankshaft Pump — Double the Lifespan

The corrosion-resistant brass-headed in-line Triplex crankshaft pump is the defining component of the P660/150's engineering superiority. A Triplex pump — featuring three pistons working in sequence — delivers smoother, more consistent pressure output with significantly reduced vibration compared to single or dual piston alternatives. The brass pump head provides outstanding resistance to corrosion from water minerals and cleaning chemicals, while the crankshaft drive mechanism is inherently more durable and efficient than wobble plate designs. SIP rates this pump configuration at double the operational lifespan of standard pump systems — a compelling commercial proposition.

150bar Maximum Pressure & 660L/hr Flow Rate

The P660/150 delivers 150bar (2175psi) of maximum pressure with an operating pressure of 130bar (1885psi) and a class-leading 660 litres per hour flow rate. This combination of sustained pressure and exceptional volume output means the P660/150 doesn't just blast dirt — it removes it rapidly across large surface areas, dramatically reducing cleaning time on expansive commercial sites, vehicle fleets, and industrial premises.

Total Stop Function — Energy Saving & Pump Protection

The Total Stop function cuts power to the motor automatically when the trigger is released and restarts it on demand — reducing energy consumption during natural pauses in use and preventing unnecessary wear on the pump and motor components. On a machine designed for extended commercial use, this function plays a significant role in protecting the investment over its operational lifetime.

Manufactured in Italy — Premium European Build Quality

The P660/150 carries the genuine credential of Italian manufacture — a mark of quality that carries significant weight in professional pressure washing equipment. Italian-built pressure washers are widely regarded as the benchmark for pump engineering and component quality in the commercial sector, and the P660/150 fully reflects that heritage in its construction, materials, and performance specification.

10m Hose with Integrated Reel — Professional Reach, Zero Tangle

The P660/150 is equipped with a generous 10-metre high-pressure hose — double the length of many competing machines — stored on an integrated hose reel for tangle-free deployment and neat storage. This exceptional reach is particularly valuable on commercial sites, large driveways, agricultural premises, and vehicle bays where constant machine repositioning wastes time and disrupts workflow.

Integrated 7.5-Litre Detergent Tank — Chemical Cleaning on Demand

The large 7.5-litre onboard detergent tank allows cleaning chemicals, degreasers, and sanitising agents to be drawn into the water stream for direct application through the lance — enhancing cleaning power on grease, oil, biological matter, and stubborn staining where water pressure alone is insufficient. The generous tank size reduces refilling interruptions during extended commercial cleaning sessions.

Stainless Steel Lance — Corrosion-Resistant Professional Quality

The P660/150 is supplied with a high-quality stainless steel lance — a component that directly reflects the machine's commercial-grade credentials. Stainless steel provides far greater corrosion resistance and durability than the aluminium or plastic lances supplied with domestic machines, ensuring consistent performance and long service life even under regular heavy use.

5 Versatile Nozzles with Accessory Holder — Complete Cleaning Flexibility

Five nozzles are included for complete spray pattern versatility, stored neatly on an integrated accessory holder that keeps everything organised and within reach. From a pinpoint jet for stubborn deposits to a wide fan for large surface coverage, the P660/150 adapts to every commercial cleaning task with the right nozzle for the job.

Extra-Large Wheels — Confident Mobility on Uneven Terrain

At 28kg, the P660/150 is a substantial commercial machine. Its extra-large wheels are specifically designed to handle the uneven ground, gravel, cobbles, and rough terrain found on commercial sites, agricultural premises, and outdoor industrial environments — keeping the machine stable and genuinely easy to manoeuvre wherever the job demands.

How the P660/150 Compares — Brushless Induction vs Standard Brush Motor Machines

Frequently Asked Questions

What makes a Triplex crankshaft pump better than a standard pump? A Triplex pump uses three pistons operating in sequence, delivering smoother and more consistent pressure output with less vibration and pulsation than single or dual piston configurations. The crankshaft drive is more mechanically efficient and durable than wobble plate designs, and the brass pump head provides exceptional corrosion resistance — all contributing to the double lifespan rating SIP attributes to this pump system.

What is the advantage of a 4-pole low-rotation induction motor? The 4-pole configuration reduces the motor's operating speed to 1450rpm — significantly lower than the 2800–3000rpm of standard brush motors. Lower rotation means less heat generation, less friction, and substantially reduced wear over time. Combined with the brushless design, this results in a motor built for sustained commercial use with a far longer service life than conventional alternatives.

Does the P660/150 require a special power supply? No. The P660/150 operates on a standard 230V 13A supply — compatible with a standard domestic or commercial socket. No specialist wiring or three-phase supply is required.

How does the Total Stop function protect the pump? When the lance trigger is released, Total Stop cuts power to the motor immediately — preventing the pump from running under load without flow. Continuous running without trigger operation generates heat and pressure within the pump system, accelerating wear. Total Stop eliminates this entirely, directly extending pump service life.

Is the 10m hose sufficient for large commercial sites? The 10m hose provides a generous working radius around the machine — double that of most domestic pressure washers. For very large sites, repositioning the P660/150 is made straightforward by its extra-large wheels, which are specifically designed for movement across uneven commercial terrain.

What nozzles are included with the P660/150? The P660/150 is supplied with five versatile nozzles stored on the integrated accessory holder. For specific nozzle angle details, please refer to SIP's full product documentation or contact us directly.

Can the detergent tank be used with any cleaning chemical? The integrated 7.5-litre detergent tank is designed for use with pressure washer-compatible cleaning chemicals. Always check that any detergent or cleaning agent used is approved for pressure washer application and compatible with the pump and lance materials. Refer to the SIP product documentation for specific guidance.
