Flow and pressure performance

Published plunger configurations.

Column headings show pump strokes per minute / pinion revolutions per minute. Flow is theoretical at 100% volumetric efficiency. Pressure is based on 90% mechanical efficiency and intermittent well-service duty. Application review is required above 15,000 psi. Maximum flow and maximum pressure are not simultaneous operating points.
