Liquid ring single-stage vacuum pumps PW1 Hydro-Vacuum

Description:

Vacuum pumps

designed for suction and pumping of dry gas with temperatures up to 150 ° С and gases saturated with vapors, characterized in that their temperature does not exceed 100 ° C, with the possibility of using working fluids with viscosity up to 60 mm² / sec and density 800 - 1200 kg / m³, the temperature of the water at the outlet of the pump should not exceed 80 ° C. Hydro-Vacuum manufactures single-stage and two-stage liquid ring vacuum pumps, PW series.<

PW series pumps

- pump and motor are mounted on a common support. The torque from the motor is transmitted to the impeller through the shaft, mounted in the bearings of the support and elastic coupling. This design makes the vacuum pump noticeably longer and heavier, but it significantly facilitates its maintenance when the pump needs to be disassembled or engine replacement. In addition, the pump is mounted on 2 supports (impeller between the bearings), which gives much longer service life of pumps than a monoblock (installed on the motor shaft or landing a worker wheels) PW1-12 - PW7-14 series liquid ring vacuum pumps are single stage vacuum pumps c productivity from 24 m³ / h to 1500 m³ / h and ultimate residual pressure up to 33 mbar.

Regardless of the operating mode (PB or PZ), vacuum pumps must have a secure supply of working fluid in quantities given in the column of the operating mode PB. When used as a working fluid water, it is recommended to use chemically treated water to limit the amount of precipitation deposited on walls of the product. Precipitation leads to rapid wear of all jointly working rubbing elements of machines. It is recommended to use water with a hardness of about 40n for two-stage and about 80n for one-stage. vacuum pumps.
