Zoom on the Pulsar W31H19
In summary, the Pulsar W31H19 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, unpainted surfaces or high reach areas
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted and fragile surfaces
- application of detergent and cleaning solutions
The Pulsar W31H19's axial cam pump, powered by an impressive 208 cc (7 hp) engine, can provide a pressure of up to 3100 PSI (approximately 52 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). The Pulsar W31H19 thus has a cleaning power of 7750 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Ducar engine.
A fuel tank with a maximum capacity of 0.3 gallon is used to store gasoline.
Design & Handling
The Pulsar W31H19 is very mobile, due to its hand truck design and approximate dimensions of D20 x W28 x H38 in. The robust metal frame guarantees longevity of the assembly. The foam-padded fixed handle adds to the W31H19 convenience of transport, while offering a comfortable grip.
Weighing 75 lbs, the unit is easy to maneuver by most people. A major component of its weight are its 208 cc Ducar engine and metal frame. Nethertheless, thanks to its two 12" never-flat wheels, the W31H19 remains very easy to manipulate and maneuver.
Along with the Pulsar W31H19 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: Detergent storage is ensured by a dedicated tank. It must be noted that the Pulsar W31H19 doesn’t come with a soap dilution mechanism. Therefore, you must always make sure that your detergent is correctly diluted. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: The 30 ft ⌀1/4" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

- Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation).
- Accessories: On top of an owner's manual (opens in a new tab) and the usual documentation to get you swiftly started, the Pulsar W31H19 also comes with wand, pressure hose, oil and spray gun.
