Parker piston pump PVP series, Parker PVP

Thread Content

The Parker PVP series of axial piston pumps have a maximum displacement ranging from 16 to 140 ml/rev, a rated operating pressure of 250 bar, and a minimum rotation speed of 500 revolutions per minute. PVP series axial piston pumps -- Product features: 1. A new type of inclined plate shaft structure along with a large compensating piston, which significantly reduces vibration and noise as well as flow fluctuations. 2. The rigid structure and design featuring high speed and low friction result in an oil pump with an even more optimal lifespan and efficiency. The models include: PVP016, PVP023, PVP033, PVP041, PVP048, PVP060, PVP076, PVP100, PVP140, etc. The main characteristics of PARKER piston pumps are: ① The head generated by a given pump at a certain rotational speed has a limited value. The flow rate at the operating point and the shaft power depend on the conditions of the system to which the pump is connected (head, pressure difference, and pipeline losses). The head changes with flow rate. ②Stable operation, continuous conveying, with no pulsations in flow rate and pressure. ③It generally lacks self-priming capability; the pump must first be filled with liquid or the pipeline must be evacuated to vacuum before it can start operating. ④Centrifugal pumps are started with the discharge line valve closed, while vortex pumps and axial flow pumps are started with the valve fully open in order to reduce starting power. ⑤Centrifugal pumps are suitable for direct drive by high-speed electric motors and steam turbines, featuring a simple structure, low manufacturing costs, and easy maintenance. ⑥It has a wide range of applicable performance; the flow rate of centrifugal pumps can range from a few to several hundred thousand cubic meters per hour, while the head can range from a few meters to several kilometers ； Axial flow pumps are generally suitable for high flow rates and low head (below 20 meters). The efficiency of centrifugal pumps and axial flow pumps is generally below 80%, with higher values reaching up to 90%. The performance curves of PARKER piston pumps show certain interdependent relationships among the various performance parameters of the pump. By testing the pump, it is possible to measure and calculate these parameter values, which can then be plotted as curves; these curves are known as the pump’s characteristic curves. Each pump has a specific characteristic curve provided by the pump manufacturer. Typically, the characteristic curves provided by the manufacturer also indicate the performance range recommended for use, which is referred to as the operating range of the pump. The Parker piston pump is an important component in hydraulic systems. It relies on the reciprocating movement of the plunger within the cylinder block to change the volume of the sealed working chamber, thereby enabling oil suction and oil compression. Plunger pumps feature high rated pressure, compact structure, high efficiency, and easy flow regulation, and are widely used in applications that require high pressure, large flow rates, or flow regulation, such as hydraulic presses, construction machinery, and ships. The Parker PV/GP series dual pumps consist of a PV series axial piston pump and a GP series gear pump, allowing for various displacement combinations. The maximum displacement of the PV series plunger pumps ranges from 16 to 270 ml/rev, with a rated operating pressure of 350 bar; the minimum rotation speed is 300 revolutions per minute, and the oil drain port is positioned at the top. The displacement of the GP series gear pumps ranges from 1.6 to 7.9 ml/rev, with a rated operating pressure of up to 210 bar.
