The patented UNx™ Fluid End technology is the cornerstone of every Jetstream pump. Since 1987, this innovative series of fluid ends has equipped thousands of industrial and plant-cleaning contractors with the most straightforward and versatile water-blasting pumps on the market. Jetstream UNx™ bareshaft waterblast pumps are industry-leading, heavy-duty pumps designed for pressures ranging from 5,000 to 40,000 psi (344 to 2,757 bar). They combine highly durable power ends with modular, field-serviceable UNx™ fluid ends, enabling quick pressure conversions without specialised tools.
