PDV22-3,81-H-M is a high speed, two-stage vacuum amplifier used in hydraulic systems for a wide range of applications. It has a robust construction, and is capable of operating reliably in conditions of extreme temperatures, humidity and pressure. It is used in a variety of industrial settings, ranging from factories and farms, to construction sites and oil fields. The PDV22-3,81-H-M is capable of creating the highest possible vacuum and pressure at the highest possible speed.

PDV22-3,81-H-M consists of two stages. The first stage is the primary chamber which houses a self-contained air-powered low-pressure cylinder and a pressure plate which moves the vacuum fluid from the primary chamber to the second stage, the secondary chamber. This is where the vacuum fluid is finally picked up by the main rotor of the pump. The rotor drives the pressure plate to the right and left side of the secondary chamber, creating the highest possible vacuum level while maintaining the pressure. The pressure plate is designed to apportion the pressure in the secondary chamber to create an even pressure distribution. This even pressure distribution allows for more efficient operation of the pump.

The pumping action of the PDV22-3,81-H-M is driven by a surge motor, which is connected to a PWM servo-motor. On reaching peak pressure, the PWM servo-motor is engaged and starts switching from negative to positive as the pressure increases. The servo-motor then controls the frequency and speed of the surge motor, thus controlling the rate of the vacuum. The vacuum generated is then used for numerous industrial applications, including the removal of heat, liquid and gas from a system.

A key feature of the PDV22-3,81-H-M is its ability to quickly respond to changing demands in pressure and change the rate of vacuum. This makes it an ideal choice for applications that require precision control over the amount of pressure and rate of vacuum. An example of this is when an oilfield needs to change pressure and rate of vacuum quickly due to varying levels of drilling pressure. The PDV22-3,81-H-M can meet these needs while providing precise control of the rate of vacuum. Its ability to respond quickly makes it a great option for industrial applications that require immediate and precise vacuum control.

The PDV22-3,81-H-M is highly efficient and reliable. Due to its robust construction, it is able to operate for an extended period of time without requiring maintenance. It is a cost-effective solution and ideal for applications that require high vacuum levels and high speed. It is also easy to install and operate making it a great choice for industrial applications.
