Oilgear C-20035 Radial Rolling Piston Pump is a constant performing, one-wau hydraulic Pump designed for use in closed-loop systems whose applications entail a high flow rate, especially when reliable performance, constant hydraulic pressure, and a longer service life are a priority. The pump has been based on Oilgear’s proven C Series radial rolling piston designs, which date back to 1921.

C-20035 is designed to meet challenging tasks, ensuring smooth and uniform hydraulic output and minimizing pulsations, which allows keeping the system in a stable operating condition. Its fixed displacement pump enables a predictable flow rate, which is ideal in critical applications performed in industries.

The Oilgear C-20035 has the highest displacement of 528.97 cc/rev to provide high flow rates relative to the size and pressure rating of the pump as well as the speed of the drive shaft. The hydraulic fluids are discharged in one direction only. The directional control valves in the system can control the flow of the hydraulic fluids in case of need.

The system operates at a speed of 900 RPM and a rated continuous pressure of 4000 psi, making it efficient and convenient for use in a high-pressure environment. The product is also rated to handle a peak pressure of up to 3000 psi.

The Oilgear C-20035 Radial Rolling Piston Pump finds applications in:

  1. Industrial hydraulic power packs
  2. High presses and forming machines
  3. Large material handling systems
  4. Manufacturing and processing machines

Though Oilgear has a recommendation to upgrade the older C-Type pumps to the modern PVV line, the C-20035 can still serve as a reliable alternative in upgrading the units that already exist. Rexton Hydraulic provides sales and service for the Oilgear C-20035 Radial Rolling Piston Pump. These pumps are perfectly suitable for various operations and are utilized in numerous tasks with excellent results.
