Having added two Silence pump series and optimized the standard series, Rexroth expands its line of external gear units to more than 5000 pump variants and over 500 motor variants available for a range of requirements in all power classes. The redesigned B and G Series pumps offer improved power, with the B featuring 7 cm3 (0.43 in3) per revolution displacement, making it suitable for the assembly of compact power packs, and the G Series offering up to 63 cm3 (3.8 in3) per revolution to meet specific demands in the upper power classes. Cast-iron bodies are available for special requirements, such as high numbers of load cycles and long service life. With the U and T Series, the Silence low noise emissions and vibration pump is available in two nominal sizes for displacements between 4 and 63 cm3 (0.24 and 3.8 in3) per revolution. The external gear pump series features a maximum operating pressure of 4000 psi (276 bar).
