Internally Self-flushing, Unitized
Mechanical Seal
The Series e-60 features a modern unitized
mechanical seal design with a stainless steel drive
mechanism that puts less torsional stress on the
seal bellows.
The pump’s open seal chamber design delivers
ample fluid circulation at the seal face, ensuring
reduced heat buildup and increased particle
removal. The result is worry-free performance
over the long life of the mechanical seal.
Impeller
State-of-the-art vacuum cast impellers provide
smooth, quiet operation.
