Spool plunger pumps in the CIS is represented mainly by pumps AVZ and NSL production of JSC "Nasosenergomash", Sumy, Ukraine. Pumps are not fastidious in operation and service, but require certain skills to operate and vacuum sobljudeny elementary rules of hygiene. Pumps with a nominal working pressure of 150 mm RT.St. Run them neposredstvenno with atmospheric pressure it is recommended that only via a throttling by-pass valve and only upon reaching the amount of vacuum pressure of about 150 mm of mercury.St. fully open the stop valve on the inlet of the pump.To avoid excessive condensation atmosfernoi of moisture in the oil pump, almost on all models installed gazoballonnyj device. A graph of the performance of the pressure for all pump models AVZ and NSL consolidated into one table. More details can be found in the instructions for ekspluatacii on these pumps.
