BERARMA PLP PUMPS CATALOG
Menu
The PLP pumps are variable-displacement vane pumps designed for low operating pressure, equipped with a mechanical pressure control device that allows the delivered flow to be instantly adjusted according to the circuit’s requirements.
Variable-displacement vane pumps are volumetric pumps; therefore, they deliver a maximum flow rate equal to their displacement multiplied by the rotational speed. The operating pressure is determined by the pressure losses that the fluid encounters along its path within the system.
When the delivery pressure (in the system) equals the pump’s set pressure, the delivered flow automatically adjusts to the values required by the system; once this value is reached, the pump reduces its flow down to zero while maintaining the pressure nearly constant. In conditions where no flow is required, the pump delivers only the oil needed to compensate for possible leakages and pilot controls.
The Berarma PLP pumps are variable-displacement vane pumps for low pressure, equipped with a mechanical pressure regulator. The delivered flow rate is proportional to the set displacement and rotational speed. When the pressure reaches the set value, the displacement automatically reduces until it compensates only for internal leakages, maintaining constant pressure.
