Technical Specifications
The Comet KM 3.11 11/120 M Classic and Classic Plus is a professional single-phase 230V pressure washer with a power consumption of 2.9 kW and a 4-pole 1400 RPM electric motor. The Classic version is equipped with an LW-KM motor pump , while the Classic Plus version uses a ZW motor pump with flanged valve, both designed for intensive professional use. The machine is equipped with an 18-litre boiler fuel tank , with a consumption of 3.5 l/h , and a 3.5-litre detergent tank for low-pressure suction.
In terms of performance, this professional hot water pressure washer works with an operating pressure of 30 to 110 bar and a maximum pressure of 120 bar , offering a flow rate of 340 to 660 l/h with an outlet temperature of up to 110°C . The maximum inlet temperature is 60°C and the machine is supplied with a 10-metre high pressure hose , an ideal configuration for professional cleaning, industrial washing and continuous technical applications.
LW-KM pump (classic model)
The Comet LW-K pump is a high-performance professional pump designed for high-pressure washers intended for continuous intensive use. The brass head with high-efficiency stainless steel check valves and the integrated automatic regulation valve ensure pressure stability and immediate response to load changes. The industrial ceramic plunger pistons , combined with hardened stainless steel guide pistons and a double seal with Buna V-seals , ensure resistance to heat and abrasion and long operating life. The finned construction , the optimized oil bath and the oversized ball bearings maintain low operating temperatures even at high speeds, while the stamped bronze connecting rods with lifetime warranty and the 24 mm S male shaft make the Comet LW-K pump a reliable, stable solution suitable for professional transmissions in industrial and commercial environments.
ZW pump (Plus model)
The Comet ZW hot water pump is designed for professional and industrial applications up to 85°C , offering high reliability under continuous load. The brass head with one-piece stainless steel check valves , full ceramic plunger pistons , and Kevlar seals ensure resistance to wear, high temperatures, and chemicals. The large, reinforced crankcase , with increased oil capacity, improves lubrication and reduces operating temperatures, while the deeper fins optimize heat dissipation. The oversized industrial bronze connecting rods and 24 mm solid shaft make the pump ideal for professional transmissions and guarantee mechanical stability, long life, and consistent performance even under intensive use.
FUNCTIONAL Specifications
Low/High Pressure Detergent Suction
In the Classic model the detergent suction system takes place at low pressure with regulation from an external tank, while in the Plus model the detergent suction takes place at high pressure with regulation of the quantity from an internal 3.5 L tank or from an external tank.
EASY START start-up
The EASY START system allows for a progressive start, reducing absorption peaks and protecting both the electrical network and the internal components of the professional single-phase pressure washer.
Professional 4-pole motor
The Comet KM 3.11 11/120 M Classic and Classic Plus is equipped with a 4-pole 1400 rpm electric motor , designed for intensive professional use and prolonged work cycles.
Delayed Total Stop and Safety Valve
The delayed Total Stop automatically shuts down the motor when the gun is released, limiting wear, overheating, and fuel consumption. The professional safety valve protects the hydraulic circuit from overpressure, while the Classic Plus version features a flanged valve and ZW motor pump for advanced technical configuration for professional washing and industrial hot water cleaning applications.
Boiler system with thermal control and delayed burner start
The professional hot water boiler integrates thermal protection, a temperature control thermostat and delayed burner start , ensuring operational stability and precise control up to 110°C . The 18-litre diesel tank with level float and filling filter allows for continuous work during intensive professional cleaning operations.
