1500 bar ultra-high-pressure water blasting at a glance
The ESF-20150 is the 1,500 bar / 21,750 psi model in the ESF-20110 / ESF-20150 range of mobile electric high-pressure washers. It pairs a low-speed electric motor with a stainless-steel pump and a built-in water tank that keeps inlet pressure stable. The specification sheet supplied with the machine rates it at 20 L/min (5.28 gpm) and 60.3 hp / 45 kW on a 380/440 V, 50/60 Hz supply, in a 1,650 x 950 x 1,220 mm frame weighing 720 kg. It is designed for continuous cleaning operations in the shipbuilding industry — hull surface preparation, rust and coating removal, deck and tank cleaning — where water blasting replaces abrasive methods.

Reading the pressure and flow figures
1,500 bar equals 150 MPa, or 21,750 psi. The valve body in the product photographs is marked 150 MPa / 21,750 psi, and the gauge is a dual-scale EN 837-1 instrument with a range to 1,600 bar / 23,000 psi, so the working pressure sits below the instrument’s full scale. A 20 L/min flow equals 5.28 US gpm. These figures come from the machine’s own nameplates and specification sheet; confirm them against the factory data sheet for the exact configuration you order.
Standard configuration
- 20 m high-pressure hose
- Water purification filter
- Overflow high-pressure gun
- Four spray nozzles
- Safety valve and dual-scale pressure gauge
- Water-inlet filter system
Main configuration and functional features
The pump is stainless steel and is driven by a low-speed motor, with a safety valve, pressure gauge and water-inlet filter system fitted as standard. Stepless pressure regulation lets the operator match the jet to the surface. The control panel carries an emergency stop and SET / RUN / STOP controls. The machine is rated for continuous operation for 24 hours and includes water shortage protection. The built-in water tank stabilises inlet supply, which matters on sites where the water pressure fluctuates.
Typical applications
Shipbuilding and ship repair: hull surface preparation, marine growth and rust removal, paint and coating stripping, deck, hold and tank cleaning. Industrial maintenance: heat exchanger and tube bundle cleaning, concrete surface preparation, and removal of paint, scale and deposits in yards and plants. For work that does not require 1,500 bar, the lower-pressure 1000bar marine high pressure cleaner (14,500 psi) is also listed on this site.
ESF-20150 versus ESF-20110
Both models share the same 20 L/min flow, the same 1,650 x 950 x 1,220 mm footprint and the same 380/440 V, 50/60 Hz supply. Moving from the ESF-20110 to the ESF-20150 raises working pressure from 1,100 to 1,500 bar, motor power from 37 to 45 kW and net weight from 650 to 720 kg. Choose the ESF-20110 for general coating removal at 1,100 bar, and the ESF-20150 where the coating or surface preparation standard calls for the higher 1,500 bar jet.
Frequently asked questions
What is 1,500 bar in psi? 21,750 psi (150 MPa) on the supplied specification sheet.
How much water does the machine use? 20 L/min, or 5.28 US gpm, for both the ESF-20110 and the ESF-20150.
What electrical supply is required? 380/440 V at 50/60 Hz.
Can it run continuously? The specification sheet states capability for continuous operation for 24 hours, with water shortage protection.
