TUSSU® SH Series High-Head Submersible Dewatering Pumps

TUSSU® SH Series is engineered as a direct drop-in replacement for Tsurumi® LH series pumps. Featuring identical discharge dimensions, shaft centers, and mounting footprints, TUSSU® SH pumps allow you to swap existing units or spare parts with zero piping or panel modifications.

Direct Tsurumi LH Interchangeability

Drop-in Replacement: Matches Tsurumi LH hydraulics, mounting dimensions, and performance curves.
Flow-Through Cooling: Top-discharge, slim-body design allows continuous operation at low water levels without motor overheating.
Built for Abrasives: High-chromium cast iron impellers and ductile iron pump casings handle sand, silt, and slurry in underground mines and construction sites.
Heavy-Duty Seal Protection: Silicon carbide dual mechanical seals housed in an isolated oil chamber keep water out of the motor casing.
