2BV2 Series Liquid Ring Pump – Compact, Efficient, and Water-Saving Design

Product Description

Product brand: NASH Product name: 2BV2 water ring vacuum pump Air pumping capacity: 27m3/h to 110m3/h Ultimate vacuum: 3300 pa Production model: 2BV2060, 2BV2061, 2BV2070, 2BV2071

Application areas: * Vacuum filtration * Pharmaceutical/laboratory vacuum * Vacuum distillation * Vacuum sterilization * Wood treatment drying * Solvent recovery * Extrusion molding * Food processing * Water pump diversion * Vacuum packaging * Liquid degassing

The 2BV series liquid ring vacuum pump is suitable for suction of gas and steam, and the suction pressure can reach 33mbar (absolute) (i.e. 97% vacuum). When the liquid ring vacuum pump works under the condition that the suction pressure is close to the ultimate vacuum (the saturation pressure of the working liquid) for a long time, it should be cooperated with the cavitation protection tube to protect the pump. When used as a compressor, the maximum pressure is 0.26 mpa (abs). As a new generation of energy-saving products, 2BV series liquid ring vacuum pumps will completely replace SK and 2SK series liquid ring vacuum pumps and W, WY, WL series reciprocating vacuum pumps with their superior performance and advantages.

Applications:

Pulp and paper industry: black liquor evaporation, vacuum dewatering machine, raw material and white water degassing system, water suction tank, sofa roller, absorption shift roller and transmission roller, windbreak box.

Chemical industry: methane gas recovery, petroleum recovery, gas collection, exhaust gas compression, steam collection, filtration deceleration, polyester production, PVC production. Power plant: condenser exhaust, water tank filling, flue gas desulfurization, fly ash transportation, geothermal gas removal, transformer vacuum pressure impregnation. Sugar industry: sewage filtration, CO2 production and more

Product Features

lCompact pump body structure, coaxial direct coupling design of pump and pump, easy installation * The rotor is directly installed on the motor shaft, no coupling required * The pump casing is directly installed on the motor casing, no centering required * The standard bronze impeller greatly improves the corrosion resistance of the pump * Adopts mechanical seal as standard configuration to eliminate leakage and reduce maintenance * Adopts patented flexible exhaust valve to ensure that the equipment is in * running state * Oil-free design, greatly reduces water consumption and is beneficial to environmental protection * It has self-priming function and is easy to operate

lDirect coupling design, easy installation, space saving. * The pump has cavitation protection port open (or connected with the separator) to ensure maximum suction, eliminate cavitation noise, protect the pump * 2BV full series adopt aluminum bronze impeller, high strength, improve its corrosion resistance and durability. If the liquid flow parts are stainless steel, the pump can operate in tougher conditions.
