Two equals one: the motor/pump hybrid system EPAI:
With the EPAI unit, Voith Turbo has succeeded in integrating the well-established internal gear pumps, type IPM (medium pressure, up to 175 bar) and type IPV (high pressure, up to 330 bar) in an asynchronous electric motor. With that, an electro-hydraulic unit is available, which is very compact in design while also ensuring remarkable low noise emissions.

Features:

• Continuous pressures up to 330 bar (IPV) or 175 bar (IPM)
• Asynchronous electric motor, 400V/3~
• Low noise levels, up to 12 dB(A) lower than the conventional motor/pump unit
• Compact design, up to 50% less space required than conventional solutions
• Very low flow and pressure pulsation
• Absence of dynamic sealing elements offers a high degree of protection against leaks
• Long service life expectancy and less maintenance through use of fewer wear parts
• Protection class IP 55, higher protection classes on request
• Designed with single or double pump
• Pressure relief and direction control valves can be attached (optional)
• Suitable for variable-speed drives (variable volume flow)

Applications:

• Low-noise compact units, mainly in industrial applications
• Systems with limited space availability (e.g. shipbuilding)
