摘要： A downhole pump including a mandrel defining a passageway therein and defining an inlet to the passageway that allows fluid ingress to the passageway from an environment outside of the mandrel and defining an outlet from the passageway that allows fluid egress from the passageway, a blade extending from the mandrel and sized for a close clearance fit in a tubular into which the pump is intended to be used, the blade upon rotation of the mandrel causing a fluid flow regime in a direction across the blade, into the inlet, through the passageway, out of the outlet and back to the blade.
