Performance data

Page 3

Performance data is valid for the range of HMC motors when fully run-in and operating with mineral oil. The appropriate motor displacements can be selected using performance data shown on pages 4 to 10. Refer to the table on this page for pressures and speed limits when using fire-resistant fluids.

Rating definitions

Continuous rating The motor must be operated within each of the maximum values for speed, pressure and power. Intermittent pressure rating Intermittent max pressure: 275 bar.This pressure is allowable on the following basis: (a) Upto 50 rpm 15% duty for periods upto 5 minutes maximum. (b) Intermittent power rating Over 50 rpm 2% duty for periods upto 30 seconds maximum.Static pressure to DNV rules 380 bar. This is permitted on a 15% duty basis for periods upto 5 minutes maximum.
