REXROTH HYDRAULIC PUMP

Service Details:

A variable vane pump is a type of hydraulic pump that can adjust its output flow rate based on system demands, unlike fixed vane pumps that have a constant output. This adjustment is achieved by changing the pump's internal geometry, allowing for efficient operation in applications with fluctuating hydraulic needs. Key Features and Function:

• Adjustable Displacement:The pump's displacement (volume of fluid moved per rotation) can be varied to match system requirements, leading to energy savings and reduced heat generation. 

Service Details:

A hydrostatic test pump is a mechanical device that exposes pressure vessels, pipes, and other containers to high-pressure water to check their integrity and strength. This test identifies potential leaks or weaknesses and assures the structural soundness of the tested components for safe operation

Service Details:

Features unique low noise generating mechanisms throughout. An energy saving type with drastically reduced power loss. NACHI's unique semi-cylindrical swashplate, a plate in which pressure is received on the surface, enables constant and stable discharge amounts.

Service Details:

The Rexroth A4VSO250 is a high-performance, variable displacement axial piston pump designed for open-circuit hydraulic systems. It has a 250 cm³/rev displacement, making it suitable for high-flow applications in industrial and mobile equipment. Key features include its high-pressure capability (up to 400 bar), durability, low noise, and a swashplate design that provides precise flow control. It is commonly used in applications like construction machinery, presses, and injection molding machines. 

Service Details:

Hydraulic pumps convert electrical energy into fluid pressure by using an electric motor to drive the pump. They are necessary for all hydraulic drives. The fluid pressure is then delivered by hydraulic fluid to cylinders and actuators and hydraulic motors at the required pressure level and volume.

At King Hydraulic, we specialize in professional Rexroth hydraulic pump repair, including models like A10VSO, A4VSO, A2FE, A4VG, and more. Whether you're dealing with performance issues, leaks, or complete pump failure, our expert technicians provide fast diagnostics, OEM-grade repairs, and full testing to restore your pump to factory specifications.

We use genuine Bosch Rexroth parts and follow strict quality control to ensure maximum efficiency and longevity of your hydraulic equipment. All pumps are thoroughly tested on our in-house test bench before returning to service.

Rexroth pump troubleshooting involves checking for basic mechanical and hydraulic issues, like low fluid levels, incorrect fluid viscosity, pump coupling damage, fluid contamination, and component wear. The process often starts with installing a pressure gauge to detect a lack of flow, then using a heat gun to pinpoint hot components, and inspecting parts such as seals, vanes, and bearings for leaks, wear, or damage. Essential steps also include verifying correct system settings, confirming the pump isn't running in reverse, and analyzing the hydraulic fluid for contamination or bubbles
