Prime 174 Hydraulic Power Units – 174 HP / 2500-4000 PSI / Up To 80 GPM

DAE Pumps Prime 174 Hydraulic Power Units provide high-quality power for your hydraulic tools and equipment through a heavy-duty diesel-driven engine. The Prime 174 offers 174 HP at an operating pressure between 2500 and 4000 PSI with hydraulic flow up to 80 GPM, and a 130 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 174 has a small footprint, this robust system has a high-capacity hydraulic cooler and a powerful Yanmar engine. This Tier 4 Final Yanmar engine is fixed speed and equipped with a 14 gallons capacity fuel tank for extended operating time. The Prime 174 is the right size hydraulic power pack for many heavy-duty tools. 

Our 174 HP hydraulic power unit provides complete power for all our 3″ and 4″ hydraulic submersible slurry pumps and many hydraulic dredge 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 174 is part of the Prime Series HPUs which offer a variety of sizes, power, configurations, and more to match your needs.
