The Hydromatic S4SD and SB4SD sewage pumps are designed to transfer raw sewage with solids as large as 3".

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
