PUMP WITH STORAGE RESERVOIR

摘要

FIELD: electric pumps with storage reservoirs known as autoclaves. SUBSTANCE: proposed pump has delivery section actuated by electric motor and reservoir with internal membrane which divides it into first entrapping chamber for water and second chamber filled with compressible gas. Delivery section is multi-stage centrifugal section which delivers liquid through inlet passage on hermetic side discharging liquid directly to first chamber of reservoir which is communicated with outlet passage. Delivery section and reservoir are mounted without connecting pipe lines or with hydraulic joints in pump housing. Delivery section is submerged in liquid of first chamber for continuous suction of liquid. EFFECT: compact construction of pump; increased productivity. 3 cl, 1 dwg
