VICKERS Variable Piston Pump PVM131 PVM141 Stamping Machine

Core Features
Compact shell structure: Using high-strength cast iron shell, the structure is very compact, with high power density, and easy to install on equipment with limited space.
Axial drive capability: The rear end of the pump can be connected in series with a PVM pump of the same specification or smaller, or a gear pump (such as the V series), as an auxiliary pump, without the need for additional connecting shafts and bearing supports, simplifying system design and saving space and costs.
Multiple control methods:
Pressure compensation control (PR): The most commonly used control method. The pump automatically adjusts its displacement to maintain the preset pressure (adjustable) of the system. When the system pressure reaches the set value, the pump's displacement decreases to only compensate for leakage, thereby achieving energy conservation and reducing heat generation. This is the standard configuration of PVM131.
Load sensitive control (LS): The displacement automatically changes according to the load demand, providing only the flow and pressure required by the load, with extremely high energy efficiency.
Electric displacement control (EP): By controlling the displacement through a proportional electromagnet, the electric proportional stepless regulation of flow is achieved, making it an ideal choice for modern automation equipment.
Constant power control (HP): Ensure that the input power of the pump does not exceed the set value, and protect the prime mover (such as motor, engine) from overload.
Remote pressure control, etc.
High performance rotating components: adopting a validated plunger shoe design and durable distribution plate, ensuring long-term operation life and low noise under high pressure.
High working pressure: The rated continuous working pressure can reach 280 bar, and the peak pressure can reach 350 bar, which is sufficient to cope with harsh industrial applications.
Excellent oil absorption characteristics: good self-priming ability, allowing for higher installation speeds and lower inlet pressures, simplifying inlet pipeline design.
