Double Cartridge: SPW-516

HydroMax Seal SPW-516 | Double Cartridge Stationary Seal with Integral Flow Inducer

The SPW-516 is a multi-spring, hydraulically balanced double cartridge stationary seal featuring an integral flow inducer, barrier fluid quench & drain ports, and O-ring secondary seals.

This Stationary Pusher Wet (SPW) Double Cartridge Seal includes shrink-fitted seal faces and is designed for use with parallel rotating equipment shafts.

With advanced design features such as directed barrier fluid flow and self-aligning seal faces, the SPW-516 ensures optimal heat removal and reliability in demanding applications. The cartridge design simplifies installation with pre-set seal faces, eliminating the risk of incorrect face load settings. It includes Quench, Drain, and Flush ports as standard.

Factory assembled and tested, the SPW-516 is suitable for use with seal support systems and compatible with Plan 52 and Plan 53 configurations.
