(1) Minimum speeds can be reduced, maximum speeds can be increased. For specific operating conditions consult out technical department.
(2) Significantly higher intermittent pressure are allowed. Consult catalog or contact our technical department.
(3) Flow shown is minimum allowed for production pump at rated pressure with 10 wt oil at 110° Fahrenheit and can be used to calculate minimum volumetric efficiency under these conditions.
(4) Indicated torque is obtained by considering the average mechanically efficiency.
