Housing: The ARK90 pump's housing is typically made of high-quality cast iron, providing durability and resistance to wear and tear.
It houses all the internal components and ensures the pump's structural integrity.
Rotary Group: This core component includes the pump's pistons, swash plate, and cylinder block. It is responsible for pressurizing the hydraulic fluid. The swash plate angle determines the pump's displacement, affecting its flow rate.
Shaft: The pump's shaft connects to the engine or motor and transmits rotational power to the rotary group. It must be sturdy and precisely machined to maintain smooth operation.
Bearings: Bearings reduce friction and wear within the pump, ensuring smooth rotation of the shaft and other moving parts. High-quality bearings are essential for the pump's efficiency.
Seals and O-Rings: These components prevent hydraulic fluid from leaking out of the pump and contaminants from entering. Proper sealing is crucial to maintain system efficiency and prevent damage.
Valve Plate: The valve plate is responsible for directing hydraulic fluid into and out of the pistons and cylinders, controlling the flow and pressure of the system.
Port Plate: This plate contains various ports for hydraulic connections, including inlet and outlet ports for fluid intake and delivery.
A spare parts repair kit is essential for the maintenance and repair of the ARK90 hydraulic pump.
These kits are designed to provide operators with the necessary components to restore the pump's functionality without the need for a complete replacement. Here's what you can typically find in a spare parts repair kit for the ARK90:
Seals and O-Rings: The kit includes a variety of seals and O-rings to replace worn or damaged ones. These ensure proper sealing and prevent fluid leaks.
Bearings: High-quality replacement bearings are included to restore smooth operation and reduce friction within the pump.
Valve Plate and Port Plate: In some kits, you may find replacement valve and port plates to address issues with fluid flow control and connection points.
Gaskets: Gaskets are provided to maintain a proper seal between different pump components.
Piston Assemblies: Depending on the kit, you might receive piston assemblies with new pistons and cylinders to replace worn or damaged parts in the rotary group.
Shaft: In some comprehensive kits, a replacement shaft may be included to address issues with the pump's primary power transmission component.
