ZW Diesel engine self-priming pump
Description
D-ZW type this`s a liquid stock cavity in the pump casing,together with the up return hole and down circulating hole to form a system of circulation .When the pump stop working,there`s some liquids left in the cavity.When the pump work again,the left liquids will be throught up together with air by impeller,the liquids will return to the cavity by the separator, the air will be pumped out,there form a certain vacuum,then has the function of self priming.
Using arrage
Compared with similar products,this pump has the merits of compact structure,good self priming function,large sewage pumping ability,high efficiency,easy maintenance.So it is an ideal product in international market.
