Shield pump manufactured by Dalian Baolong Pump Manufacturing Co., Ltd. has obvious advantages compared with petrochemical process pump.
1 flammable and explosive conditions: the use of mechanical seal of the petrochemical pump, seal principle of the closure of the mirror ring to form a liquid film at high speed rotation, the machine seal cooling. There are hidden dangers of leakage. Shielding pump machine explosion-proof, completely leak-free. Explosion-proof grade DIIBT3 / DIIBT4, protection class: IP54 / IP55, more suitable for flammable and explosive conditions;
2. Petrochemical process pump according to API610 standard, according to machine seal standard API682 in PLAN11 / PLAN11 +52 program comparison: import pressure is too large, resulting in PLAN11 machine seal service life is short. PLAN11 +52 program led to procurement costs are too large. The selection of shielding pump can be designed according to user requirements pressure, do not have to consider the import pressure.
3. The use of cost comparison: In addition to the impeller, the pump body and other components, two years of spare parts of petrochemical pump general to be reported bearing / mechanical seal / shaft nut / shaft / bearing retainer / Plum pad / coupling / machine seal Cover, etc., while the shield pump generally only need to report the bearing / sleeve + thrust plate can be.
