Model S4SD, SB4SD

Submersible Sewage Dual Seal Pumps, 4" Discharge

The Hydromatic S4SD and SB4SD sewage pumps are designed to transfer raw sewage with solids as large as 3". 4" Discharge Submersible Sewage Ejector Pump Models available:

  • S4SD:  1150 RPM
  • SB4SD:  1750 RPM
Key Features
  • The fully enclosed oil-filled motor efficiently dissipates heat and locks out moisture so you receive reliable pumping service
  • The mechanical dual seal is constructed with a ceramic stationary face and a carbon rotating face for long service life
  • The impeller is a two-vane semi-open design for efficient operation without clogging; the impeller has pump-out vanes to prevent material buildup around
  • stainless steel shaft eliminates corrosion and fatigue to give longer pump life; the minimum shaft overhang decreases deflection and increases seal life
