Oilgear DN Type 230 HP Legacy Hydraulic Pump is a high-capacity variable displacement pump designed for heavy-duty industrial applications that demand strong output, maintained pressure control, and long life operational stability. Being part of the DN Series, this pump carries on the legacy of Oilgear in making hardy hydraulic solutions capable of handling demanding work in continuous-duty environments. Capable of a maximum operating speed of 900 RPM with a continuous pressure rating of up to 3000 psi, the DN Type 230 HP pump gives reliable performance where high power and controlled flow are indispensable.
This legacy pump is designed to handle huge hydraulic loads with ease while sustaining system behavior that is both smooth and agile. Its variable displacement allows the pump to adjust its output automatically to match any prevailing system resistance, ensuring thereby power use efficiency and only when required. As the operating conditions change, instantaneous reaction of the pump keeps pressure and flow stable without dissipating excessive amounts of energy as heat. This intelligent response works to improve overall system efficiency while reducing wear on hydraulic components.
The Oilgear DN Type 230 HP pump features a radial rolling piston configuration, which increases its durability and also enables it to operate effectively even with high pressure and torque. The two-way hydraulic operation of the Oilgear pump facilitates reverse flow, and as a result, it simplifies the hydraulic circuit, as fewer directional and flow control valves are required. This simplified hydraulic circuit increases its responsiveness and also helps to ensure smoother machine operation.
The DN Type 230 HP is a legacy product but still a trusted option when it comes to maintaining or upgrading hydraulic systems that were originally based on Oilgear DN Series technology. The DN Type 230 HP still has its uses due to its robustness, reliability, and performance. However, for new applications, newer models might be preferred; nevertheless, for maintaining existing hydraulic systems based on Oilgear DN Series technology, the DN Type 230 HP still makes for a good option.
