I. Overview: 
 FZB series of green ring fluorine plastic self-priming pump is combined with non-metallic pump in accordance with international standards and process design and manufacturing. Pump using a metal enclosure lined plastic, over-current components are made by a fluorine plastic alloy manufacturing, pump cover, impeller, etc. with metal insert parts outsourcing fluoroplastics overall sintering pressed, seal with the exterior advanced bellows mechanical seal , choice of 99.9% alumina ceramic (silicon carbide) in the stationary ring, snap ring with PTFE filler material, its corrosion resistant and excellent sealing. Import and export of pumps are used to cast steel reinforcement to increase the pump pressure. The actual use of the display, the pump has corrosion resistance, wear resistance, high temperature, not aging, high mechanical strength, smooth operation, advanced and reasonable structure, strict and reliable sealing performance, easy maintenance, demolition, long life, etc.. 
 Suitable temperature: -50 ℃ ~ 120 ℃ 

 Second, the design characteristics and principles: 
 The most prominent feature of the FZB self-priming pump is self-priming, pumping may be lower than the pump installation location below the liquid, and stable performance, simple operation, just after the pump before the first use irrigation fluid, the second and subsequent without irrigation fluid, you can boot directly, self-priming height medium density within 2-4 m to determine the best choice of the alternative body heavy liquid pumps. 
 Green Circle FZB self-priming pump working principle is: filled with liquid in the pump body and pump before the first boot (or pump housing itself there is liquid). Impeller high-speed rotation after the start of the original liquid in the pump row to the exit of the air-water separation chamber when the pump is the entrance to the formation of a vacuum, so that the inhalation of air into the pump tube, on the other hand, the impeller discharged to the air-water separator Room of the water due to a continuous supply of liquid to promote and flows back to the impeller suction at the entrance, with just the inhaled air mixture, the formation of a mixture of gas and water, a mixture of gas and water through the impeller row to gas and water separation chamber, the gas will be discharged go, the water will return to the pump chamber, and so forth, until the air drained, smoking and the Sheung Shui to. 

 Third, the pump seal: 
 The pump uses the most advanced, externally mounted PTFE bellows mechanical seal, with multiple layers of protection, extending the life of the mechanical seal, the transport medium containing impurities in granular media, can be equipped with a single face of cooling water is hard on the hard (silicon carbide silicon carbide) mechanical seal, the user selection when taking into account the solid content in the media. 

 4, pump special precautions: 
 Installation 
 Reach using the site. Pump by long-distance transport, must be inspected prior to installation machine parts are intact, fasteners should be tightening, check the pump shaft and motor shaft concentricity, if the shift should be corrected. 
 Installation to minimize the loss of hydraulic suction line shall not be fitted in less than 90 ° elbow 90 ° elbow of the import pipeline is not more than 2, the pump inlet should be set up filters, prevent chunk impurities from entering the pump to ensure the pump is capable of normal operation of the installation as much as possible to reduce the import pipeline a long way (this will reduce the import pipeline air, thereby reducing the time of self-absorption, increase work efficiency). 
 (3) the inlet of the connecting bolts must all force tighten tight seal must be tight, and must not leak, and to make use of a soft flange gasket (Viton), otherwise it will seriously affect pump self-priming performance. 
 Operation precautions 
 Check the operation of the motor running direction of the pump direction flag are the same, not to reverse! 
 (2) The pump body shall be filled with liquid to start running, the air operation is strictly prohibited. Self-priming pump in the prescribed height range 7 to 10 minutes is not yet out of the liquid should be shut down immediately check the reason (mainly the inspection of imported pipe leaks to prevent the working fluid within the pump warming, damage to the pump. 
 3 for the first time after the injection fluid in the pump body generally do not need another injection fluid, but the downtime, long or stop seal leakage exists, loss of liquid inside the pump, check the pump memory solution in the second car should be preceded by, Flooded and then drive. 
 Winter long-term when not in use, drain the pump body fluids against freezing, not working properly.
