BZ SELF-PRIMING PUMP
BZ Self-priming pump is a new pattern of energy-saving pump in 1990s．It has simple structure，stable function and feature of less noise．It is sealed by way of ceramic-ring mechanic ,so such pumps are corrosion resistant、alkaline-resisting、high temperature-resisting and nontoxic．This pump is smaller size but produce larger flow rate，higher pump head．And it is easy and safe to install，maintain and handle．It can be used in various industrial fields，such as chemical、pharmaceutical、mining、dyes and food industries，also used for water supply and drain in mining industry 、washing sector、fire-fighting sector and building trade。Any other filtering machine equipment can support its` use and when fixed with a nozzle in farm and orchard such pump turns to a sprayer．
