The HAWE R 51.0-AT radial piston pump from Germany belongs to the 6016 series, featuring six cylinder rows with a maximum flow rate of 51 l/min, a displacement of 36.1 cm³/rev, a maximum pressure of 350 bar, and a piston diameter of 12 mm.
Considering bearing service life, when the pump operates continuously under 75–100% load (e.g., accumulator charging or similar pressurization tasks), the maximum allowable working pressure should not be fully utilized. If pressurization is indeed required, a pump with a similar displacement but a higher pressure rating should be selected.
Installation Instructions:
Whether the HAWE R 51.0-AT radial piston pump is mounted externally as a motor-pump unit or installed inside the tank as a complete hydraulic power unit, it is essential to ensure that the pump is positioned below the oil tank's liquid level. The cylinders are arranged in a star configuration within the pump housing, forming a closed assembly. Therefore, the pump can only be properly vented during or after oil filling.
