Our diesel engine driven water pumps that are mounted on a trailer can easily be transported from one location to another. The high-power self-priming pump features robust self-priming capability, enabling automatic gas evacuation from the suction line without pre-filling water and quickly initiating normal operation. This characteristic makes it particularly advantageous in scenarios requiring frequent relocation or height-restricted installations. For instance, it is extensively utilized in agricultural irrigation and firefighting water supply applications.
