Product description: as a standard mechanical seal design actually solves the problem of leakage, reducing the maintenance of equipment; the design of flexible exhaust valve to ensure that the entire operating range in a better state. Compact is the feature of 2BV series, 2BV2,2BV5 rotor directly installed on the motor shaft without coupling, pump shell directly installed on the motor shell without centering, the standard configuration of bronze impeller to improve the corrosion resistance of the pump; The standard mechanical seal design actually reduces leakage and equipment maintenance, and the flexible exhaust valves ensure that the entire operating range is in good condition. The stainless steel 2BV6 series is suitable for more demanding environments. 2BV rotating part-impeller, through the rotation of the working fluid in the elliptical pump to form a liquid ring. At the same time, the working fluid plays the role of sealing medium, compression medium and cooling medium three, no wear, no lubrication.
In the exhaust phase, the liquid ring gradually away from the hub, the pumping medium along the axial exhaust outlet. Because the impeller is eccentric with respect to the rotating liquid ring, the fluid moves back and forth in the space between the blades-like a piston moves in a cylinder-pumping and compressing the pumping medium. In the suction stage, the impeller gradually away from the hub, the pumping medium along the axial suction port suction. Running through the whole, in the tight installation site, compact design is undoubtedly a major advantage, 2BV than the domestic traditional liquid ring pump, the volume is reduced by about 30% . Because the noise of 2BV is very low, with a soda water separator, of which 50% can be recycled, further reducing the cost of operation. Closed-loop systems can limit the generation of wastewater and reduce the need for supplemental fluids. The condensate produced in the pumping medium can be recovered and reused. Zero Maintenance, 2BV all design features make it essentially maintenance-free. Oil-free design, no need for oil, of course, no need to replace the oil filter equipment. Under normal use, the average bearing only 5 years plus once grease. Under normal operating conditions, the 2BV mechanical seal does not need to be adjusted as regularly as the packing seal.
