NLB compatible fluid ends

The Jetech AD Liquid End combines durability and high-performance design, optimized for easy maintenance and rapid servicing.
Its advanced structure includes a patented quick-lock valve mechanism and a single-spring system, reducing maintenance demands by up to 50%. Each cylinder and valve is individually accessible, enabling straightforward maintenance and conversions that can be completed in minutes.
Thanks to its modular design, Jetech AD liquid end is easily converted between pressure ranges — 10,000 to 20,000 psi or 20,000 to 40,000 psi — by a simple stuffing box kit swap, without needing to change manifolds or valves, a unique capability in the waterjetting industry.
With fewer moving parts, the AD Liquid End increases uptime and longevity, even under pressures up to 50,000 psi, making it ideal for rigorous, high-pressure applications.
Replacing Your NLB Fluid End with Jetech AD Liquid End
If you’re facing high costs and complex conversions with NLB pumps, it’s time to consider the Jetech AD Liquid End.
Designed for seamless integration, the AD Liquid End serves as a fully compatible, drop-in replacement for fluid ends in models like the NLB 225 or NLB 325, delivering enhanced reliability and simplified maintenance at a fraction of standard OEM conversion costs.
For example, if you need to convert an NLB 305 diesel unit from 20,000 psi to 40,000 psi, the standard NLB conversion kit would require a costly manifold replacement.
Jetech, however, offers a cost-effective AD Liquid End replacement ready to meet 40,000 psi requirements straight off the shelf, plus an optional stuffing box kit for conversions back to 20,000 psi. This setup provides flexibility and allows you to switch between 20,000 and 40,000 psi pressure ratings, or any other pressure in between, with ease by simply using an additional stuffing box kit from Jetech.
With Jetech, you benefit not only from cost savings but also from the flexibility, ease of service, and reliability that come standard with Jetech’s AD Liquid End technology.
