Hydraulic units series P32 type
Purpose
Hydraulic units of the P32 type are designed for individual drive of the working bodies of hydraulic single-column presses from 100 to 2500 kN with a hydraulic pusher-ejector and without a hydraulic pusher-ejector. Hydraulic unit works on pure mineral oil with viscosity of 21-260 mm 2 / l at oil temperature ranged from 10 to 60 o C and the operating fluid temperature from 1 to 45 o C according to GOST 14066-68.
The cleanliness class of the working fluid is not lower than 12 according to GOST 17216-71. The nominal fineness of filtration is 25 μm. Recommended brands of oils: ИГП-30, ИГП-38, ТУ3.810.1413-78, ВНИИ НП-403 GOST 16728-78.
