Oilgear DN Type 300 HP Legacy Hydraulic Pump is designed for high-power applications and environments where a high level of hydraulic power is required. The DN Series of pumps was developed to support the high functionality and continuous operation of high-pressure machines. The design of the DN Type 300 HP pump reflects a maximal operating speed of 1200 RPM and a continuous working press Maximally of 3000 psi. The machine is capable of delivering high and continuous horsepower.

The Variable Displacement Legacy Pump has a variable displacement feature that makes the pump able to control the amount of fluid being discharged autonomously depending on the requirement of the system. The pump will not run at full capacity all the time but will vary the amount of displacement according to the amount of resistance. In turn, the result will help in extending the lifespan of the entire system.

The Oilgear DN Type 300 HP pump also features a strong radial rolling piston mechanism that is suitable for high torque and high-pressure applications. The two-way hydraulic system supports reversed flow funtionality. This allows it to work with fewer direction-control valves. The pump is beneficial in that it results in smoother system performance. This is because it results in low-pressure shock. The system also is beneficial because it increases system response accuracy.

Even though the DN Type 300 HP is considered a legacy product, this does not stop it from being a reliable option for maintaining, overhauling, and upgrading existing systems that originally used Oilgear’s DN Series technology. In fact, many industrial facilities still continue to use this particular pump due to its mechanical durability, predictable power output, and historical success in continuous duty operations. Even though there might be more advanced models available for upgrading existing systems, such as enhanced pump technology, this particular model is not a bad option regarding compatibility and hydraulic precision.
