Hydraulic unit model 9П61А
Purpose
Hydraulic units type 9П61A (9P61А) are designed for individual drive of hydraulic press working elements with a force of 630 ... 2500 kN.
The hydraulic units operate on pure mineral oil with kinematic viscosity of 50-200 mm2 / s at oil temperature of 15 ... 50°C and ambient temperature of +1 ... +45°C.
Cleanliness class of working fluid is not lower than 12.
Recommended brands of oils: ВНИИ НП-403, ИГП18, ИГП30, ТУ3810.1413-78, И20, И40А.
