Hydraulic unit model У27.908Е
Purpose
The hydraulic unit model У27.908E (U27.908E) is designed for individual drive of hydraulic press bodies for pressing special mixtures with 63 ton-force. The operating conditions of the hydraulic unit make it possible to use it in an explosive atmosphere.
Category of placement is 4.2 in accordance with GOST 15150-69. The hydraulic unit operates on pure mineral oil with kinematic viscosity of 20-400 mm2 / s at oil temperature of 10 ... 55оС and ambient temperature of +1 ... +40°С.
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, ТУ.3.810.1413-78, ВНИИ НП-403.
