GENERAL DESCRIPTION
Pumps P04 are high pressure variable vane pumps equipped with hydraulic pressure regulating device that allow you to instantly adjust the flow rate accordingly to circuit requirements. Variable displacement vane pumps are volumetric type so they deliver a maximum flow rate equivalent to its displacement for their speed of rotation. Operating pressure is due to pressure loads encountered by the fluid within the system. When the outlet pressure (on the system) equals the pump setting pressure, the flow rate is adjusted to the values required by the system. When this value is achieved, pump reduces its flow rate to zero, keeping the pressure almost constant. In zero flow conditions, pump delivers oil only to compensate any possible drain and piloting.
The new series of P04 pumps was created as a response to the increasingly stringent requirements for energy saving and noise reduction on compact hydraulic systems, where usually are used fixed displacement external gear pumps. This new series of pump gathers 60 years of experience and innovation applied to hydraulic pumps. It allows high performances combined with extremely compact dimensions, maintaining high standards of solidity (robustness) and reliability. Replacement of external gear pumps with P04 pumps on systems where work cycle includes pressure and / or speed control phases allows to:
- Reduce the number of components on the system
- Â Reduce power consumption
- Â Reduce oil heating
- Â Reduce or avoid heat exchangers installation
- Â Significantly reduce noise
The series of P04 pumps is supplied with:
- Standard mounting flanges and shafts
- Â Gas BSP standard port connections
- Â Max. flow regulator device to mechanically reduce pump max. displacement
- Â Different types of devices for hydraulic, electric and proportional control for flow rate and / or pressure
- Â Different types of seals depending on the type of fluid and operating temperature
What makes the Berarma P04 series pumps a unique product of its kind?
- 210 bar operating pressure
- Â Extremely small overall dimensions that allow the replacement of external gear pumps size 1
- Â New functional concept of the pressure compensator device (reduction of peak pressure values and response times)
