A Proven Design to Provide Extended Mechanical Seal
With multiple configurations available the Model A9 offers an ideal environment for all sealing options, especially the precision components used in mechanical seals. Available in oversized tapered and cylindrical designs, the robust A9 seal housing offers features proven to extend service life.
- Oversized taper seal housing is self-venting and removes heat build-up from seal faces
- Flow is recirculated in the seal area, removing solids and homogenizing two phase fluids
- Pressure balance holes transmit the lowest possible pressure to seal for reduced wear and seal drag
- Fluid is recirculated by pump out vanes to promote heat removal and solids expelling
Robust Shaft Design
Wilfley designed the Model A9 with an incredibly stout power frame system that offers maximum precision and fortified positioning for single and double mechanical seals. This heavy duty design achieves industry dominating load capacity and L3/D4 values while still providing a sleeve to isolate the shaft from the pump fluid.
