Low-Noise External Gear Pump
By DE staff
Fluid Power RexrothRexroth’s SILENCE PLUS features a noise level reduced by 15dB(A).
Rexroth introduced SILENCE PLUS, a generation of external gear pumps whose noise level has been reduced by an average of 15 dB(A) compared with a conventional external gear pump, the company says. The design key is the non-involute helical gearing, which uses its tooth profile for continuous fluid delivery. The internal axial forces generated in the helical gearing are cancelled out in a wear-free manner using hydrostatic bearings. The SILENCE PLUS will be available successively in sizes from 12 to 28 cm³/rev.
