CYZ-A self-priming centrifugal pump is based on the relevant technical information at home and abroad through digestion, absorption, improved after the development of the latest pump products, the pump for the oil industry, land oil depot, the ideal product tanker, and It is suitable for oil cargo pump, bilge pump, fire pump, ballast pump and machine cooling water cycle. It supplies petroleum products such as gasoline, kerosene, diesel oil and navigation coal, seawater and clean water respectively. The medium temperature is -20 ℃ -80 ℃, Such as the transfer of chemical liquid can use corrosion-resistant mechanical seal. CYZ-A self-priming centrifugal pump features: 1, the pump is a self-priming centrifugal pump, it has a simple structure, easy operation, stable operation, easy maintenance, high efficiency, long life, with strong self-absorption capacity Etc. No need to end of the valve in the pipeline, just to ensure that the pump body before storage can be cited quantitative oil. Used in tankers or ships on water, can double as a stripping pump, stripping a good effect. 2, the pump is made of high quality materials refined, sealed with carbide mechanical seal, durable, spit out the pipeline does not require the installation of safety valves, suction pipe without the need to install the bottom valve, thus simplifying the piping system and improve Labor conditions.
