Product Description General InformationType WLZ,WZY pump,derived from three advanced kinds of national patents and developed by our factory is our country's pioneering product.It adopts installation of vertical type featuring save occupied area.Meanwhile,the series of pump is subject to start without liquid filling and is characterized by short time self-suction,especially suitable for the work condition of frequent start,boasting advantages of non-leakage,reliable operation and maintenance-free. ApplicationThis kind of pump is widely used in the fields of petroleum,chemical,metallurgy,power station,steel,mine,paper-making,electroplating,environmental protection,fire-extinguishing,architecture and sewage treating.Part of them can take place of inundated pump,long-shaft pump or pump started frequently.It is suitable for delivering clear water,sea water,sewage with little particles(no fiber) ,industrial waste water,oil and other medium with corrosion.

It has the features of space-saving and less cost for construction.It needn't dismantle inlet and outlet pipes while maintenance.2.ControllingPump can be equipped with controller which can automatically start or stop pump according to liquid level,and give an alarm for over loading.Pump can work automatically without any help of people.3.Self-priming diskSelf-priming disk is subject to air-water vane segregate design with multiple passages(self-suction disc) which is capable of completing self-priming process in a quick time,even 1/3-1/2 much shorter than that of WFB with single volute pressure water chamber.The pump has small cubage and light weight.4.Drive modePump is connected with motor through rigid coupling.Viewed from the motor end,the rotating direction of pump is clockwise.5.ImpellerThe impeller adopts closed structure with excellent performance.compared with WFB pump type of open structure,its efficiency is 10%-15% much higher and the permissible installing suction depth is 0.5-1m deeper.In the meanwhile,the motor power of this kind pump can be much lower than that of other pumps with the same performance parameters,so it saves more energy.6.Vacuum-destroy modeThis type of pump has air balance-hole and U pipe which can automatically break siphon,and when pump stops operating,siphon system can not pump all water out of pump,so only if pump be injected with liquid upon first start,it can be free from refilling permanently.Why Us
