Oilgear C-3525 Radial Rolling Piston Pump is a constant delivery, one-way hydraulic pump specifically designed to serve open-loop hydraulic applications that require a stable flow rate and a long service life. With a rich history in the C Series line of Oilgear’s legendary products, the C-3525 continues to use a radial rolling piston architecture that has been in service in the industry for a period exceeding a century.
This particular pump has been designed to provide smooth and accurate flow rates with reduced pulsation even in a continuous duty. Since it has fixed displacement characteristics, it will provide predictable performance in machines where accurate control of flow rates is required. The radial rolling piston design of this particular pump will provide low wear and tear inside it.
The maximum displacement for the Oilgear C-3525 stands at around 117.93 cc/rev, and this ensures reliable flow discharge depending on the selected size of the pump, the operational pressure, and the rotational speed of the drive shaft. The hydraulic fluid will flow in one direction, although it will be possible to reverse the flow by using the system directional valves if the need arises.
Oilgear C-3525 is designed to operate at a maximum RPM of 1200 RPM, and it also features a maximum pressure rating of 3000 psi and a continuous pressure rating of 3000 psi. The pressure ratings of the pump not only enable the pump to work under continuous pressure but also withstand the pressure peaks.
Every Oilgear C-3525 pump is provided with an adjustable relieving valve that safeguards against overload pressure within the hydraulic circuit. The available input shaft rotation options of these pumps include clockwise rotation, counterclockwise rotation, and reverse. Additionally, the manufacturer offers other models such as the CG type of these pumps that involve the inclusion of built-in gear pumps and relieving valves used within the pilot valves or auxiliary valves.
