1. Introduction-SVP –Servo Variable-speed Pump (each pump 25 cc ~250 cc) SVP system is formed by pressure and flow double closed-loop control. The power and speed of whole press system is optimum adjustable, after SVP replaces the classic AC motor and pump system. • Pressure and flow double closed-loop control • ESTUN servo system • PQ Decoupling control algorithm • Rexroth (or specified) Internal gear pump

1. Introduction-SVP • Permanent magnet synchronous servo motor • PQ Decoupling control algorithm • 40%~80% Energy saving • 1‰ repeatability precision • ± 0. 3 bar accuracy • ± 0. 1 mm Injection • Flow response 20 ms • Pressure response 70 ms • Decompression time 120 ms Energy saving High Efficiency Accuracy Durable • Triple protection • high overload capacity

2. Features, Advantages & Benefits Product features Advantages Benefit No need valve control system high efficiency, low power consumption up to 80% energy saving, Block-based design, compact oil tank 50% less Installation volume high productivity, easy to install, retrofitting position, pressure and flow triple closed-loop control Up to 80% Hydraulic oil saving Accurate, maintenance free Full process monitoring System self-diagnose Low failure rate Total solution is ready for use Short developing, designing, and installation time. extremely testing, training and maintenance costs saving. Specially designed algorithm for hydraulic system
