Product Details

High capacity monoblock pumps

Available in both cast iron and stainless steel construction,the 2BV5 family provides capacities up the 600 m 3/h (360 CFM) in a compact monoblock design.

Space-saving installation

When compared to conventional pumps, the 2BV5's monoblock design delivers the benefits of a simple, compact and economical installation. Since the pump and motor are integral and self supporting, there is no need for additional baseplates, couplings or guards, which add to the cost, complexity and overall size of the installation.

Rugged and reliable

We focused on durability and dependability when we developed these liquid-ring pumps.

With a reinforced stainless steel shaft andsealed bearings, the 2BV5 can provide up to 20,000 hours of maintenance-free operation.

Additional features such as the iron pump's ceramic coated casing prevent wear and ensure constant performance, even under harsh conditions.

Quiet operation

The 2BV5 is expertly designed and manufactured to be quiet and vibration free. With sound pressure levels of less that 75 dBA, it complies with the strictest noise standards, eliminating the need for additional sound attenuating devices.

2BV Liquid ring vacuum principle

The impeller is mounted off-center in the approximately cylindrical casing. When the impeller revolves at the direction as shown in the Figure, the working liquid is thrown against the inner of the casing by centrifugal force and forms a cylindrical liquid ring with uniform thickness. As a result, a crescent chamber is developed between the inner surface of the liquid ring and the impeller hub. As the impeller rotates to Point B from Point A, the chamber space between adjacent vanes increases gradually, and the gas is drawn in. As the impeller rotates from Point C to Point A, the corresponding chamber space decreases gradually to compress the gas drawn in previously. When the pressure is equal to atmospheric pressure, the compressed gas is expelled through the discharge port.
