Key Specifications & Features
- Design: Valve-controlled radial piston arrangement with 2, 3, 5, or 7 pumping elements.
- Pressure & Flow: Available in 28 displacements and 7 pressure ratings (up to 550 bar / 700 bar depending on model).
- Rotation: Bi-directional (no restriction on direction of shaft rotation).
- Mounting: Face mounting, intended for external mounting horizontally outside an oil tank, though they can also be submerged.
- 1RC vs. 1RCE Difference:
- 1RC: Basic radial piston pump with casing.
- 1RCE: Includes an extension shaft for through-drive, allowing for the coupling of an additional low-pressure pump.
