CZ Series Trailer-Mounted Diesel Engine Water Pumps

Product Description

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.
