Pump ATEX

Berarma ATEX pumps

ATEX pumps are low- or high-pressure variable-displacement vane pumps with a mechanical (PLPX), hydraulic (PHPX) or constant-power (PHPKX) pressure regulating device that allow the flow rate delivered to be instantly adjusted according to the circuit demands.

Variable displacement vane pumps are positive displacement pumps; therefore, they deliver a maximum flow rate equivalent to its displacement times its rotational speed.

The operating pressure is due to the pressure drops that the fluid encounters as it travels through the system. When the discharge pressure (on the system) equals the set pressure of the pump, the flow rate delivered adjusts to the values required by the system; once this value is reached, the pump reduces its flow rate to zero, keeping the pressure nearly constant. Under conditions of zero required flow rate, the pump delivers only oil to compensate for any leakage and piloting.
This series of pumps is certified for applications in potentially explosive atmospheres.
