KCB stainless steel gear pump for mildly corrosive or hygienic conditions at the same time without solid particles and fiber media, the temperature does not exceed 280 ℃, the viscosity of not more than 2000cst lubricating liquid. For different conditions, can design a variety of stainless steel pump products for different corrosive media. Common stainless steel gear pump main material is 304,316,316 L stainless steel. All stainless steel gear pump parts and components of all the materials through special chemical treatment, with high corrosion resistance, wear resistance and pressure resistance. Stainless steel gear pump main products are forgings products, ordinary sand casting products, casting products and silica sol casting products. The appearance of compact, beautiful, low noise, long life and other characteristics. Is the chemical and corrosive equipment supporting the preferred product. KCB series stainless steel gear pump gear involute helical gear structure, the use of corrosion-resistant fluorine rubber skeleton oil seal and PTFE packing combination of high temperature sealing, sealing effect, high temperature. Special conditions can be stainless steel corrosion-resistant mechanical seal. Stainless steel gear pump gears are common spur, helical, herringbone, helical teeth, tooth profile are mainly involute and arc type. Usually small gear pump to use more involute spur gear, high temperature gear pump often use variable gear, conveying high viscosity, high pressure melt polymer melt more use of involute helical gears. Gear and shaft made of one, its rigidity and reliability is higher than gear and shaft separately manufactured gear pump. Foreign low-pressure gear pump gear is often used square structure, that gear tooth width equal to the addendum circle diameter. The high-pressure occasions used in high-viscosity gear pump gear tooth width less than its tip diameter, which is to reduce the gear radial compression area, reduce gear, bearing load. Stainless steel gear pump is a new type of liquid conveying machinery, with the advantages of simple structure, safe and reliable operation, convenient use and maintenance, continuous and uniform liquid discharge, and stable pressure.
