China Danfoss 45 series FRL hydraulic pump | replacement parts

Pump Housing: The pump housing serves as the main body of the pump and provides a secure enclosure for the internal components.

It is typically made of durable materials like cast iron or aluminum alloy, ensuring strength and longevity. The specifications for the pump housing include dimensions, bolt patterns, and port sizes, which need to match the original housing for proper fitment.

Rotor and Vanes: The rotor is a crucial component responsible for creating the pumping action. It features specially designed vanes that trap and transport hydraulic fluid within the pump. The rotor and vanes should be manufactured to precise tolerances to maintain efficient fluid displacement. Material composition, dimensions, and vane profiles should adhere to OEM specifications.

Shaft and Bearings: The pump shaft transfers rotational motion from the driver to the rotor, enabling fluid displacement. It must be strong, durable, and precisely machined to minimize wear and ensure smooth operation. Bearings support the rotating shaft and help reduce friction. Specifications for the shaft and bearings include material type, dimensions, and tolerances.

Seals and Gaskets: Sealing components are crucial to prevent fluid leakage and maintain system efficiency. Replacement seals and gaskets for the Danfoss 45 series FRL hydraulic pump should meet OEM standards for material composition, dimensions, and pressure ratings. Common types of seals used include O-rings, lip seals, and mechanical face seals.

Valve Plates: Valve plates control the flow of hydraulic fluid within the pump. They consist of channels and ports that direct the fluid to the appropriate sections. Replacement valve plates must match the original specifications in terms of dimensions, port sizes, and pressure ratings to ensure proper operation and compatibility with other system components.

Springs: Springs are used in the pump to provide tension and assist in the movement of various components.

They need to meet specific strength and compression requirements as specified by the OEM. It's important to ensure that replacement springs have the correct dimensions, material composition, and load capacities.

Fasteners: Various fasteners such as bolts, nuts, and screws are used to secure different parts of the pump together. It's essential to use replacement fasteners that meet or exceed the original specifications in terms of material strength, thread size, and length. Using incorrect or substandard fasteners can compromise the integrity of the pump assembly.
