Hydraulic Fit

The DMX is engineered to perform reliably at the required hydraulic capacity while mitigating thrust loads. In addition to ensuring reliable performance, bearings and seals last longer thanks to an innovative design that optimizes axial and radial thrust balance over the full operating range, virtually eliminating shaft deflection and vibration. This inherent hydraulic balance allows both seal chambers to operate at pump suction pressure.

Bearing Arrangements

The DMX is offered with a variety of bearing and lubrication designs, including:

- Standard self-aligning, anti-friction radial bearings

- Thrust consisting of two single-row, angular-contact anti-friction bearings

- Split-sleeve radial and ball thrust

- Split-sleeve radial and tilting pad thrust

Standard lubrication is via an oil ring system, which incorporates a constant-level oiler and a sight glass. This system prolongs bearing life by ensuring oil penetrates the bearings without foaming. Oil mist and pressure lubrication options are also available.
