"We converted the 600 from 10 to 20K in no time..."

Next-Generation Engineering

By using ductile iron and other high-quality materials, PSI's power ends are made to operate at higher horsepowers, resulting in higher frame loads, giving our customers the ability to run higher flow rates.


Lowest Cost of Operation Pump in the Industry

The NX-Series pumps, engines, and transmission drive trains have been engineered to place the engines at its BEP (Best Efficiency Point), resulting in substantial fuel savings and longer lasting life on drive train components, as well as the pump. The standard 352, 365, 465, and 600 HP engines operate at up to 10 DBA quieter than other manufacturers. An Eaton Fuller heavy-duty transmission is installed for maximum flexibility and fuel economy.


Low Profile Platform

The NX-Series low profile trailers offer a lower center of gravity, making them easier to access and safer to transport.

pressure gauge due to specific discharge ports for each pressure range. This feature also means the pump cannot be operated with a conversion kit which does not match its rupture disc. The unique pressure-specific conversion cartridges simply lift out of the fluid end, making PSI's pump the quickest conversion in the industry.


Safest Pump in the Industry

The patented fluid end ensures the NX-Series pumps cannot be operated at any pressure higher than the fluid end components installed, making it the safest high-pressure water blasting pump to operate.


Quickest Pressure Conversion in the Industry

PSI's patented fluid end features the only discharge manifold in the world rated for all pressures up to 40,000 psi (2,800 bar), also making it the quickest conversion in the industry.

The NX (Next Generation) high-pressure water blasting pump units are simply best-in-class. Leading the industry in safety, maintenance, flexibility, performance, cost of operation, and reliability, the NX-Series pumps will provide its users with the ultimate in operational flexibility and safety. With the combination of PSI's standard transmission and its electronically controlled engine, operators can match virtually any nozzle size with the unit deispalcment, thereby making it the most efficient method of transferring energy from the engine to the nozzle tip with no by-pass or flow control.


The heart of the NX-Series is PSI's patented fluid end conversion system, making it the only pump in the world capable of operation throughout its pressure range of 8,000 psi to 40,000 psi (550 bar to 2,800 bar) with a single discharge manifold for all discharge pressures. Additionally, there is no need to change or remove the accessory manifold, rupture disc assemblies, or

“The ability to convert this pump from 10K to 40K, in the field quickly, and easily, is brilliant.”
