Siemens Answers with the SINAMICS Servo Pump — Optimized Efficiency for Modern Hydraulic Systems

SINAMICS Servo Pump

Highest Efficiency Down the Entire Line

High efficiency, superior dynamics and low noise emission are crucial criteria when developing state-of-the-industry hydraulic systems. The Siemens servo pump solution is based on the SINAMICS S120, SINAMICS G120 and SINAMICS V20 drives in combination with SIMOTICS S servomotors, SIMOTICS M main motors and SIMOTICS GP 1LE1 motors. The Siemens extensive and flexible product portfolio supports the appropriate, tailored combination of components – from top performance through cost efficiency requirements.

The functional principle used is simple: Hydraulic fluid is moved only as required – it’s not the pump, but the pump drive that makes the difference – a theory that can be applied to almost any hydraulic system. The Siemens servo pump generates only the energy required in the relevant process phase. This yields a significant savings effect, particularly during times where the hydraulic cylinder rests and therefore no power (intervals) or little power (maintaining pressure with inactive cylinder) is required. During a break, the pump is virtually stopped and requires significantly less energy compared to solutions during which the pump continues running.

Shorter Payback Period for Your Investment
- usually less than two years.

Based on Standard Components

SINAMICS Drive Modules in Blocksize & Booksize Formats

The SINAMICS servo pump solution is based upon a variable speed drive powering an electric motor that is coupled to an internal gear pump. It’s built using standard components such as the SINAMICS S120 drive and distributed I/O. This allows fast and simple access to replacement parts — and, as a result, secures the highest availability and productivity of your hydraulic system.
