Features as Follow

All diesel water pump units are ideal for industrial or agricultural applications.
Â
All pumps have silicon carbide mechanical seals that resist corrosion, wear better, and handle heat more effectively than standard seals.
Â
The long-lasting high-end silicon carbide seals are suitable for heavy-duty applications such as pumping contaminated or abrasive fluids.
Â
The cast iron impeller and volute reduce vibration and wear on the mechanical seal and engine, extending their lifespan for semi-trash operations.
Â
Excellent fuel consumption: average operating time per tank of fuel is 12 hours. Auto-return decompression ensures efficient starting in all temperature conditions. Easy to operate, durable aluminum.

Used in the Process of Possibility of Failure and Solution

Problem Cause Solution

1. Water pump not priming Water diversion, water pump and pipeline leak. Suction height is too high, wrong rotation direction, insufficient speed. Packing loose or worn. Add water, tighten the water inlet joint screw, reduce the suction lift, change the direction of rotation, increase speed, compress packing or replace it.

2. Flow rate is too low Bottom valve jam, impeller blockage, high suction height, packing wear. Clear the jam, lower the suction height, increase speed, replace the packing.

3. Pump power consumption Impeller wear, bearing damage. Replacement.

4. Pump overall vibration Improper fixed installation, impeller damage, pump shaft bending. Reinstall the fixed unit, replace the impeller, replace the spindle.
