Gearbox vibration limits
WebAug 3, 2024 · For a given capacity, vibration levels of a PCP are necessarily higher than other API 676 pump types based on concentric motion. A standard PCP may exceed the limit of 3.8 mm/s (para 6.11). This low frequency vibration is inherent in the design and not a sign of trouble, thus vibration monitoring makes little sense.
