FB type the pump be applicable to not imply the solid grain to lie the quality, and lie the quality temperature to O ℃ the ～ 120 ℃ , import the pressure not very in 2 kgs/ cm2. AFB type it is improvement design that stainless steel bear to decay to leave the heart pump on the F type bear the foundation of the corrosion pump of, all adopt the new to pay a motive stalk seal to equip, and belong to the type of single arm of single class to bear decay to leave the heart pump. That pump with transport to lie the quality contact over the partial spare parts of , and all adopt 1 Cr18Ni9Ti material manufacturing. Used for to transport to not contain the solid grain, and have the causticity liquid, and is transported to lie the quality temperature is-20 ℃～ 130 ℃s, pump import the pressure not very in 2 kgs/ cm2.
