S4000L - Pedestal Rotary Gear Pump

The S4000L is a high-performance stainless steel rotary gear pump engineered for demanding food-grade applications, especially maple syrup filter press systems. Designed as a direct drop-in replacement for the N4000L model, this pump offers superior durability, chemical resistance, and operational flexibility. Its rugged construction and food-safe materials make it ideal for handling abrasive sugar sand, filter aids, and high-temperature fluids up to 220°F (104°C).

Advantages:

  • Engineered for Maple Syrup Processing: Specifically tailored for filter press systems. 

  • Superior Durability: Withstands abrasive materials like sugar sand and filter aids. 

  • Food-Safe Materials: Meets stringent food-grade standards. 

  • Flexible Installation: Operates in any direction and orientation. 

  • Low Maintenance: Features high-quality components and easy lubrication access. 

  • Reliable Performance: Positive displacement design ensures consistent flow and pressure. 

  • Stainless Steel Construction:
    Investment cast stainless steel housing ensures long-lasting durability and corrosion resistance. 

  • Food-Grade Certified:
    Fully compliant with "Biofood" standards, safe for use in food processing environments. 

  • Drop-In Replacement:
    Seamlessly replaces the N4000L model without modifications. 

  • Versatile Operation:
    Can operate in either rotation direction and be mounted in any orientation. 

  • High-Temperature Tolerance:
    Handles raw sap up to 220°F (104°C).and hot water flushing at 140°F (60°C).

  • Graphitized Silicon Carbide Bearings:
    Provide excellent wear resistance and extended service life. 

  • Hardened Stainless Steel Shafts and Gears:
    Enhance strength and reduce maintenance needs. 

  • Viton O-Ring and Teflon Packing:
    Ensure leak-free performance and chemical compatibility. 

  • Self-Priming with Suction Lift:
    Capable of lifting fluids up to 20 feet (6.1 m) on the suction side. 

  • Lubrication Fittings Included:
    Simplifies maintenance and extends operational life.
