2BV2 071 Water Ring Pump Used for Vacuum Rotary Drum Filter
The 2BV2 071 water ring pump is a low-pressure, single-stage pump that operates based on the vacuum pump theory. It is primarily used as an air pump and is powered by electricity. The pump body and impeller are made of stainless steel or cast iron, providing durability and resistance to corrosion.
This pump is commonly used in various applications, such as extruders, autoclaves, sterilizers, milking machines, and grinding machines. It is designed to handle different power capacities ranging from 0.81KW to 15KW, and the motor voltage, frequency, and phase can be customized according to specific requirements.
The 2BV2 071 water ring pump belongs to the single stage directly connected liquid ring vacuum pump type. It features a small volume and compact structure, allowing for easy installation in a horizontal position without the need for a chassis.
The pump works based on the water ring principle. The impeller is eccentrically installed inside the pump body, creating a liquid ring (concentric with the pump body) when the pump is in operation. The impeller transfers motor power to the liquid ring, causing the liquid ring to pulse periodically between the impeller vanes. During the pulsation, gas is suctioned in through the disk suction inlet and discharged from the disk exhaust vent.
