The KOSHIN KTH-100DHES is a heavy-duty 4" diesel trash pump engineered for high-capacity dewatering, site drainage, and sewage handling. It combines a rugged pump end with a diesel powerplant and electric start for reliable, jobsite-ready performance.

Key specifications & performance

• Inlet / Outlet: 4" (100 mm) connection — industry-standard, easy to couple to hoses and fittings.
• Flow rate: up to approximately 2,050 L/min (≈542 USG/min) depending on configuration.
• Maximum head: ~20–30 m range depending on model variant and impeller — suited for long-lift dewatering.
• Solids handling: designed for trash duty with a large impeller throat to pass debris and suspended solids.
• Engine: diesel powerpack (electric + recoil start available on DHES variants) for extended runtime and site reliability. Many KTH diesel builds are paired with robust diesel engines in the Hatz family for commercial duty.

Durability & serviceability

Built with a heavy-duty pump volute and hi-chrome cast impeller, SiC mechanical seals and a protective roll cage, the KTH-100DHES emphasizes abrasion resistance and low-maintenance service intervals—ideal for construction, municipal and emergency dewatering tasks. Quick clean-out access reduces downtime for routine maintenance.
