The PV080 is a compact-sized pump with a maximum displacement of 80 cc/rev, while the PV092 has a displacement of 92 cc/rev.
These pumps are suitable for applications that require moderate flow rates and pressures. They feature a variable displacement design, which allows the output flow to be adjusted according to the system requirements. This feature not only improves efficiency but also enables precise control over the hydraulic system.
Moving up in displacement, the PV140 offers a maximum displacement of 140 cc/rev, making it suitable for applications that require higher flow rates. The PV180 and PV270 have even larger displacements of 180 cc/rev and 270 cc/rev, respectively. These pumps are ideal for heavy-duty applications that demand high flow rates and pressures.
All of these pumps operate on the axial piston principle. They consist of a rotating cylinder block that houses several pistons, which are positioned in radial slots. As the cylinder block rotates, the pistons reciprocate due to the eccentricity of the cylinder block. This reciprocating motion creates a pumping action, drawing in fluid through the inlet and forcing it out through the outlet.
The displacement of these pumps can be adjusted either manually or automatically.
Manual adjustment is typically achieved by controlling the swashplate angle, which determines the stroke of the pistons. Automatic adjustment can be achieved through various methods, such as electronic controls or pressure compensators. This flexibility in displacement control allows the pumps to adapt to different operating conditions and optimize energy consumption.
These pumps are designed to handle a wide range of hydraulic fluids, including mineral oils, synthetic fluids, and biodegradable fluids. They feature robust construction with high-quality materials, ensuring durability and long service life. The pumps are also designed for ease of maintenance, with easily replaceable wearing parts and accessible service points.
In terms of performance, these pumps offer high overall efficiency, which translates into reduced energy consumption and operating costs. They provide smooth and precise control over the hydraulic system, ensuring accurate positioning and response. The pumps are also designed to operate at high speeds, allowing for efficient power transmission in demanding applications.
