Glossary of petroleum Industry

pump off
to pump (a well) so that the fluid level drops below the standing valve of the pump and it stops working. To prevent pumping off, a pump must be installed at the proper depth in the fluid.

Pump off occurs when the fluid level in the well bore is not sufficient to
completely fill the pump. Continuing to pump in this state can induce damaging shock loads
known as "fluid pound" causing excessive wear and possible damage to the rod string. Once
shutdown occurs, the pump remains off for a predetermined "downtime" to permit fluid build up in
the well bore before resuming.
