Buy Eaton Smf23 6423-279 6433-042 Hydraulic Pump | Partsdic®

The Eaton SMF23 6423-279 and 6433-042 hydraulic pumps are part of Eaton's extensive product line, known for their durability and high performance.

These pumps belong to the fixed displacement axial piston category, meaning they deliver a constant flow of hydraulic fluid regardless of the system pressure. They are commonly used in industrial systems that require a steady and continuous power supply.

One of the key specifications of these pumps is their displacement capacity. The Eaton SMF23 6423-279 pump has a displacement of 23 cc/rev (cubic centimeters per revolution), while the 6433-042 pump has a displacement of 33 cc/rev. This displacement value represents the volume of hydraulic fluid delivered by the pump in a single revolution. The higher the displacement, the greater the flow rate and power output of the pump.

Both pumps feature an axial piston design, where a series of pistons move in a circular motion within a cylinder block. This design ensures efficient fluid delivery and minimizes energy losses. The pistons are actuated by a swashplate mechanism that converts the rotary motion of the input shaft into the reciprocating motion of the pistons. This mechanism enables precise control over the fluid flow rate and pressure.

The Eaton SMF23 6423-279 and 6433-042 hydraulic pumps have a maximum operating pressure of 250 bar (3625 psi). This high-pressure capability makes them suitable for demanding applications that require significant force and power, such as hydraulic presses, heavy machinery, and industrial lifting equipment. The pumps are designed to withstand these high pressures and provide reliable operation in challenging environments.

To ensure long-lasting performance, these pumps are constructed using high-quality materials.

The cylinder block and valve plate are typically made of robust cast iron, providing excellent durability and resistance to wear. The pistons are often made of hardened steel or other wear-resistant alloys to withstand the repetitive motion and high-pressure conditions. These materials contribute to the pumps' longevity and reliability, reducing maintenance requirements and downtime.

Another notable feature of the Eaton SMF23 6423-279 and 6433-042 hydraulic pumps is their compatibility with various hydraulic fluids. They can operate with different types of fluids, including mineral oils, synthetic oils, and biodegradable fluids, depending on the specific application requirements. This flexibility allows users to choose the appropriate fluid for their system, considering factors such as temperature range, viscosity, and environmental considerations.
