QXEH Series Pump
Internal Gear Pump – up to 280 bar with One Gear Stage, 10,0 – 160,5 Displacement cm³/rev.
Energy-efficiency and productivity for fixed – and variable-speed drives. The QXEH series consists of single-stage pumps for both constant and variable speeds. Thanks to the use of high-precision gear parts with a pinion shaft (pinion and shaft as one component), extremely low pulsation levels are produced even at low speeds. In highly dynamic servo drives with reversing operation, the QXEH pumps offer maximum reliability.
In the overall product portfolio of QX internal gear units, the QEXH – as a single-stage pump with a maximum operating pressure of 280 bar – is positioned between pressure ranges 2 and 3 of the QX internal gear pumps.
The pumps in the new QXEH range are single-stage units that use just one pair of gear wheels. Their compact and heavy-duty construction introduces a new and pioneering benchmark for pumps. The improved dimensional stability of all rotating components results in higher overall rigidity levels, and this in turn decisively enhances the performance ratings of the QXEH pumps.
In addition, a vital improvement to the hydrodynamic lubrication of the ring gear has been implemented by regulating the flow profiles in the critical bearing areas by means of selective oil supply.
The good inlet characteristics, and the extremely low noise emissions, even at high speed, are ensured by our tried and tested special gear-tooth technology.
