ZW self-priming non-blocking sewage pump is a novel structure developed on the basis of repeated research on similar technologies at home and abroad. Compared with other similar products, self-priming sewage fire pump...

Diesel self priming pump is suitable for urban environmental protection, construction, fire protection, chemical, pharmaceutical, dye, printing and dyeing, brewing, electric power, electroplating, papermaking, industrial and mining washing, equipment cooling, etc.

The principle of the diesel engine self priming pump is to use the flow velocity of the water. The impeller drives the pump impeller to pump water onto the river bank. The pump can be pumped by throwing it into the river, but water flow must be in a hurry or where there is a drop.

Application of frequency conversion energy-saving technology. For diesel engine multistage pump with design parameters greater than the actual operating conditions, after installing the variable frequency speed control device, it always runs in the high efficiency zone.
