Single-stage single-suction full stainless steel corrosion-resistant centrifugal pump

Product Overview
FB type anti-corrosion pump is a single-stage single-suction cantilever centrifugal pump. The factory absorbs the characteristics of various anti-corrosion pumps and uses advanced hydraulic models. Compact and beautiful appearance, high efficiency and energy saving, stable performance, etc.

Product Features
FB type corrosion resistant pump has stable and reliable performance, good sealing performance, beautiful appearance, convenient use and maintenance. The main parts of the pump body, pump cover, impeller, shaft sleeve are made of stainless steel. FB type adopts mechanical seal device. Single-end or double-end mechanical seal is selected as required. Water in the sealing cavity is flushed with a certain pressure to wash the frictional end surface for cooling. The temperature of the medium is between -20 ° C and 130 ° C. Flow: 2-400m3 / h ;, head: 10-105m.

Product use
FB type anti-corrosion pump is suitable for chemical, petroleum, metallurgy, light industry, printing and dyeing, pharmaceutical, environmental protection, seawater desalination, offshore oil extraction, papermaking, food, power generation and other industrial sectors to transport organic or inorganic chemical media without solid particles, petroleum products And corrosive liquids. It can also be used for water supply and drainage of enterprises and cities.
