BLN/MV Vacuum Pump
Single-stage vacuum pumps with rotors between bearings and sealed by gaskets or mechanical seals.
Operational Parameters
Capacity: ___ up to 10.700 m3/h
Vacuum: ___ up to 160 torr
Project Features
- The BLN/MV series liquid ring vacuum pump operates with auxiliary liquid (usually water) in a controlled quantity. As the rotor rotates eccentrically inside the casing, the liquid is driven by centrifugal force to the periphery of the casing. The rotor blades are immersed in the liquid ring, which is formed up to the level of the hub of the ring at a point on the periphery of the ring, with only the tips of their blades immersed at the opposite end of the ring. As the rotor blades, which are fully immersed, rotate, only their tips are immersed in the liquid ring, creating an empty space in the cavities between two consecutive blades. These cavities coincide with the inlet port through which air or process gases are induced. In a similar but reversed sequence, the air or gases are expelled through the outlet port of the side plate at the other end. The degree of vacuum achieved depends on the energy supplied to the liquid by the rotor speed and the characteristics of the auxiliary liquid used.
- Sealing by gaskets or mechanical seals;
- BLN/MV series liquid ring vacuum pumps are composed of sides, rotors, and eccentric body;
- They have eccentric intermediate elements made of carbon steel and a chrome steel shaft;
- The pumps can be manufactured in stainless steel ASTM A 744 Gr.CF8 and CF8M (AISI 304 and 316), subject to consultation for other special alloys or mixed materials.
Advantages
- When sucking dry or saturated gases, it allows the entry of liquids that may be entrained;
- Reaches a vacuum of 30 mbar;
- Low noise and vibration levels.
Applications
- BLN/MV liquid ring vacuum pumps are used in a wide range of industrial processes where medium vacuums are used, such as degassing, cooking, deodorization, deaeration, concentration, condenser exhaustion, distillation, solvent recovery, plastic extrusion, vacuum filtration, centrifugal pump priming, vacuum packaging, among others, always subject to consultation.
