CZ Series Trailer-Mounted Diesel Engine Water Pumps

Features of CZ Series Self-Priming Diesel Engine Water Pump Units:

High-Performance Vacuum System: Large exhaust capacity, high vacuum efficiency, low-temperature operation, maintenance-free design, oil-free lubrication, and mechanical seal-free structure.

P-S-P Auto-Switching System: The EVP self-priming system automatically switches to standby mode once the centrifugal pump completes priming. It reactivates instantly when re-priming is required.

Dry-Run Protection System: Built-in dry-run protection prevents mechanical seal burnout during prolonged dry operation of the priming pump.

Efficient Cooling System: High-pressure cooling water flows from the centrifugal pump’s maintenance port into one end of the vacuum pump’s cooling chamber and rapidly exits from the opposite end. This enables rapid and efficient cooling, ensuring minimum operating temperatures and extended EVP system lifespan.

Easy-Disassembly Structure: The vacuum pump cover on the non-drive end is easily removable, allowing quick withdrawal of vacuum pump vanes for wear inspection.

Non-Clogging Impeller Design: Wide-flow-channel impeller ensures smooth passage of solid particles up to 76 mm in diameter.

Self-Cleaning Slag Discharge: A slag-discharging pump cover prevents seal spring jamming caused by sediment accumulation, eliminating seal failures.

Dingbo Power mobile diesel engine water pumps demonstrate versatile functionality across multiple sectors:

Flood Control & Disaster Relief: Rapid deployment to disaster zones for emergency flood drainage, mitigating threats to lives and property.

Municipal Drainage: Efficient removal of urban road waterlogging and sewer blockages to restore traffic and urban operations.

Construction Sites: Foundation pit dewatering and concrete slurry transfer, enhancing on-site efficiency and safety.

Agricultural Irrigation: Flexible water supply solutions for farmland, orchards, and drought-prone regions.

Firefighting & Industrial Operations: Critical support for fire suppression and hazardous liquid transfer/discharge in chemical plants, oil facilities, and industrial complexes.
