40kW Dual-Pump High/Low Pressure Module
Water-Cooled PMSM, IP67 Protection for Sweepers & Flushers
Product Overview
The Dual-Pump High & Low Pressure Water Pump Module is a powerful, integrated pumping solution engineered for demanding sanitation vehicle applications. It combines a 40kW permanent magnet synchronous motor (PMSM) with dual-pump configuration to deliver both high-pressure and low-pressure water output from a single, compact module.
Designed for continuous duty (S1 operation), this module provides reliable water flow for multiple functions simultaneously—high-pressure washing, dust suppression, and low-pressure irrigation—making it ideal for advanced sweepers, street flushers, and multi-purpose sanitation trucks.
