Ambient -15 to +60 °C (5 to 140 °F)Fluid -15 to +80 °C (5 to 176 °F)
Seal material FKMPilot pressure supply2) ExternalOperating fluid Mineral oil according to DIN 51524 , HFD, others upon requestViscosity Allowable viscosity operational range 12 to 100 mm2/s (12 to 100 cSt)
Recommended hydraulic fluid viscosity class VG 46 to VG 100 according to ISO 3448 ; maximum viscosity 500 mm2/s during start-up with electric motor at 1,800 r/min
System filtration • NAS 1638, class 9 • ISO 4406, class 20/18/15; obtained with filter fineness of β20 = 75
Installation position AnyInstallation note To avoid pump damages the housing pressure pL must not exceed the pressure
in the low pressure line (pA or pB) by more than 1 bar. Design the drain line with lowest possible pressure losses. Maximal pump speed is preload pressure dependent on suction line, see diagram below.
1) Maximum housing pressure pLmax, pSp = f(n), see diagram below 2) For option N1 (dual displacement) only
Moog Electrohydrostatic Pump Unit and Electrohydrostatic Actuation System
Moog Electrohydrostatic Pump Units (EPU) are emerging as a viable option for industrial machine builders as the design combines the best of both electro-mechanical and electro-hydraulic technologies. The EPU is a highly integrated, compact alternative to traditional hydraulic solutions.
This catalog describes the Electrohydrostatic Pump Unit used in such electro-hydrostatic actuation systems, like the Moog EAS. The EPU is able to operate in 2 or 4 quadrant operations and has a mechanical interface, which allows to connect it directly to hydraulic cylinders or manifolds.
The Moog EAS is a modular actuation system comprised of a Electrohydrostatic Pump Unit (EPU), Servo Drive (MSD) and manifold. Adding a cylinder as part of the system is also a common option.
