Question by: Hubert C on Mar 28, 2025, 10:18 AM
How does the internal charge pump in this Danfoss/Eaton hydrostatic pump improve its performance?
Answer by: Customer Support on Mar 30, 2025, 6:26 AM
The internal charge pump in the Danfoss/Eaton hydrostatic pump is a key feature that enhances its overall performance. It helps maintain system pressure and assists in the smooth operation of the pump, especially in heavy-duty applications. This makes it well-suited for demanding environments where consistent performance is critical.

reckon this danfoss eaton pump is meant for closed circuit setups?
Answer by: Customer Support on Jul 6, 2025, 5:06 PM
Yeah, the Danfoss/Eaton Series 2 focuses on heavy duty closed circuit hydrostatic pumping with servo control and an internal charge pump built right in.
Question by: Daryl T on Feb 9, 2026, 9:12 AM
Got a Series 2 heavy duty closed circuit application that needs servo control - will this pump handle that kind of setup?
Answer by: Customer Support on Feb 10, 2026, 1:16 PM
Absolutely, servo control applications are exactly what this pump was built for. The Series 2 heavy duty design gives you the closed circuit operation with integrated charge pump functionality, so you get precise control response along with the reliability needed for demanding servo applications. The built-in charge pump means you won't need separate auxiliary pumping, which simplifies your hydraulic circuit considerably.
