Detail

HAWE R 3.3-1.7-1.7-1.7-1.7A radial piston pump employs the classic valve-less axial port distribution principle with radial pistons. Its fundamental structural characteristic involves multiple pistons arranged radially around the drive shaft. Through the rotational movement of an eccentric shaft or bearing, the pistons are driven to perform reciprocating motion within the cylinder bores, thereby achieving oil suction and discharge.

Based on its multi-outlet and high-pressure characteristics, pumps such as the HAWE R 3.3-1.7-1.7-1.7-1.7A are typically used in high-pressure equipment requiring independent or coordinated operation of multiple actuators. For example:

Construction Machinery: In certain complex hydraulic systems, providing independent oil sources for different working devices (such as booms, buckets, and travel mechanisms).

Industrial Hydraulic Equipment: Used in machinery such as presses, bending machines, and injection molding machines that require multi-stage pressure or flow control.

Special Vehicles: Driving multiple hydraulic functional units in equipment such as fire trucks and rescue vehicles.

Usage Considerations

Oil Cleanliness: To ensure the long service life and reliable operation of high-pressure piston pumps, strict requirements for hydraulic oil cleanliness must be met, and high-efficiency filtration systems must be installed.

Correct Installation and Alignment: The pump must be installed to ensure precise alignment between the drive shaft and the prime mover, avoiding additional radial forces and extending the service life of the bearings and pump.
