Prime 38 Hydraulic Power Units – 38 HP / 2250-3000 PSI / Up To 17 GPM

DAE Pumps Prime 38 Hydraulic Power Units provide high-quality power for your hydraulic tools and equipment through a heavy-duty diesel-driven engine. The Prime 38 offers 38 HP at an operating pressure between 2250 and 3000 PSI with hydraulic flow up to 17 GPM, and a 25 gallons hydraulic tank capacity. This powerful HPU system delivers the force and torque needed to operate a variety of power tools. 

Even though the Prime 38 has a small footprint, this portable and robust system has a high-capacity hydraulic cooler and a powerful Isuzu engine. The Isuzu engine is equipped with a 12 gallons capacity fuel tank for extended operating time. DAE Pumps Prime 38 is the right size hydraulic power pack for many heavy-duty tools. 

The Prime 38 provide complete power for all our 3″ hydraulic submersible slurry pumps. These hydraulic power systems include high-quality and carefully designed safety, environmental, and maintenance features. Our high-performance HPU is designed without a diesel particulate filter (DPF). By doing so, we have eliminated the tremendous maintenance headaches caused by active regeneration used by other engine manufacturers.

The Prime 38 is part of the Prime Series HPUs which offer a variety of sizes, power, configurations, and more to match your needs.
