Oilgear C-1225 Radial Rolling Piston Pump was designed as a constant-delivery, one-way hydraulic pump intended for use in an open loop hydraulic system where a certain amount of dependability, performance characteristics, and useful life are required. The C-1225 was not the only Oilgear model offering hydraulic performance dependability going back to 1921. That honor belonged to their C Series.
The C-1225 is designed to provide smooth, quiet operation with a robust rolling piston mechanism. This provides a stable flow of hydraulic fluid even in diverse industrial settings. Its reliable design makes it a preferred option in many settings where performance is a major factor.
Oilgear C-1225 has a displacement of 36.65cc/rev, which enables accurate control of the hydraulic flow rate based on the pump size, pressure rating, and the rotational speed of the drive shaft. The fluid movement occurs in one direction, and the use of directional control valves may be necessary when there is a need to reverse the flow in the hydraulic circuit.
It operates at a maximum speed of 1800 RPM and entails a rated continuous pressure of 2500 psi along with a rated peak pressure of 3000 psi. This makes it capable of handling not only the constant pressure but also the peak pressure.
Oilgear C-Type pumps are provided in several pump sizes with varying flow rates at 2500 psi and normal drive speed. This allows system designers to select pumps with flow rates corresponding to particular applications. In addition, these are provided with flanges and an adjustable relief valve to prevent overloads in the hydraulic system and are offered with clockwise, counterclockwise, or reverse input shaft rotation.
Oilgear C-1225 Radial Rolling Piston Pump is designed for durablity in heavy duty applications, this model used in a variety of applications in the industrial world in applications involving hydraulic fluids. Other recommendations made by Oilgear are to upgrade C Type pumps to the newly designed PVV type in applications involving technological updates.
