Long-life materials - Valves and more are precisionmachined of high-grade stainless steel, and hardcoated for durability.

• Simple maintenance – Time-saving features include
5-minute packing change.
• Rebuild to extend ROI – After 20,000 hours, some
pumps are done for. Ours are designed to be rebuilt
and keep on working. You can see the entire range of
NLB units — with pressure, flow and horsepower data
— on Pages 6-11.
Replacement pumps, too
NLB pumps are built for continuous, trouble-free
operation, using a simple design proven in countless
applications over more than four
decades. Their
mechanical efficiency
is simply outstanding.
One reason is a heavyduty power frame that
provides stability,
gravity lubrication,
and easy access to
take out packing
and plungers for
inspection…
without removing
the stuffing box.
Although these pumps were
designed for NLB units, they also
make great replacements when
pumps wear out in other
manufacturers’ units.

NLB pumps have set the standard for performance and
reliability since 1971. Our triplex and quintuplex plunger
models operate at low rpm to minimize wear and
simplify maintenance. These proven designs are
regularly updated with the latest materials and
features to keep operating costs as
low as possible.

Units for any application, up to
40,000 psi (2,800 bar)
With 41 units to choose from —
27 of them convertible to
different pressures and flows —
NLB pumps can handle just about any
application you throw at them. Many are available with
either a hard-working diesel engine (trailer-mounted for
easy towing to job sites) or an energy-efficient electric
motor. Either way, you
get:
• 97% operating
efficiency – Advanced
engineering means
minimal turbulence
and 97% efficiency at
10,000 psi (700 bar).

NLB is known for the quality of its
high-pressure and ultra-high
pressure water jet pump units.
These include 27 models that you
can convert to different operating
pressures without a manifold
change — you simply change the
cartridge, which usually takes less
than 20 minutes.
Our convertible units operate at pressures from 4,000 psi to 40,000 psi
(275-2,800 bar). Choose the level of
power that best suits your needs,
from 60 hp to 600 hp (45 kW to
450 kW). They have a high degree of
commonality — the 125, for example,
is a smaller version of the 225, 325
and 605 — and few parts. All are
easy to operate and maintain, too.
