GRH Gear Pump Characteristics - GRHiaffeS^tt By far largest number of premature failures of gear pumps are due to contamination; filtering with clogging indicating and alarms is recommended. The initial contamination of the fluid must not exceed class 10 NAS 1638. Pass experience has shown that even brand new fluid often exceed this value. In this case it is recommended below 60pm inlet side, and in the return side. nas 1638 log....
