API Plan 22 adds a strainer to Plan 21. Flow is routed from the discharge side of the pump, through a strainer, an orifice, and a cooler before being returned to the seal chamber. The addition of pressure gauges on either side of the strainer allows the strainer to be monitored for servicing. In dry climates, air-cooled tubing arrangements are preferred to reduce common issues associated with water cooled systems.
