Notes
1 The value of FEED characteristic is calculated.
2 ATTENTION! After the first launching the rig should pass through 60-hours breaking-in. During the breaking-in the value of PRESSURE characteristic should not exceed 75 % of mentioned one. After the termination of the breaking-in you should discharge hot oil from the pump and gear-box, wash the oil reservoir and fill up with fresh oil.
3 * Overload capacity of discharge pressure in appropriate plunger diameter, at which the rig can operate for a short period of time.

The unit on-stream time at any regime is limited by the reheat temperature of oil in pump frame crankcase.
