Self-priming centrifugal pump is based on the relevant technical information at home and abroad through the digestion, absorption, improved after the development of the latest pump products, the domestic blank unique, the self-priming centrifugal pump for the oil industry, land oil depots, tankers It is suitable for marine cargo oil pump, bilge pump, fire pump, ballast pump and machine cooling water circulation. It supplies petroleum products such as gasoline, kerosene, diesel oil and navigation coal, sea water and clean water respectively. The medium temperature is -20 ℃ ~ 140 ℃, such as the transfer of chemical liquids can be used corrosion-resistant mechanical seal. Self-priming centrifugal pump Features: The pump is a self-priming centrifugal pump, self-priming centrifugal pump has the advantages of simple structure, easy operation, stable operation, easy maintenance , High efficiency, long life, with strong self-priming capability, etc. The pipeline does not need to be the end of the valve, just before the work to ensure that the pump body can be stored quantitative oil can be used for tankers or water ships, Can double as a stripping pump, stripping effect is good.
