Glossary Z
Z - symbol for pump hydrodynamic size.
Zero percent head loss NPSHR (NPSH0) - the lowest net positive suction head
required (NPSHR) by a pump that will result in no, or zero, head loss from its
original performance curve obtained when the pump is tested with ample NPSHA.
The standard criteria for establishing NPSHR is based on three percent head
loss, or NPSH3. NPSH0 is sometimes specified in high energy application to
provide the pump with extra margin of protection from cavitation damage.
Zymaxx - a commercial brand of composite material containing carbon fibers
used in making pump parts such as bearings, bushings, wear ring inserts, etc.,
comparable to those made of Peek material.
