Fluoroplastic pump

Fluoroplastic pump

1. Overview of fluoroplastic pump

The fluorine plastic alloy pump is designed according to standard size. The pump body is organically combined with metal and polyfluoroethylene propylene (F46). The pump cover, impeller and shaft sleeve are all made of metal inserts outsourcing the fluorine plastic integral computer temperature control sintering press molding, shaft seal It adopts external bellows mechanical seal, the static ring is made of 99% alumina ceramic or silicon nitride, and the moving ring is made of tetrafluoroethylene filling material, which is corrosion-resistant and wear-resistant. It is suitable for conveying any concentration of sulfuric acid, hydrochloric acid, acetic acid, hydrofluoric acid, Nitric acid, aqua regia, strong alkalis, strong oxidants, organic solvents, oxidants and other strong corrosive media under harsh working conditions are currently one of the strong corrosion-resistant materials. Avoid running, spilling, dripping, and leakage. Fluoroplastic alloy pumps are widely used in chemical industry, acid making, alkali making, smelting, rare earth, pesticides, dyes, medicine, papermaking, electroplating, electrolysis, pickling, electronic components, scientific research institutions and other industries .

2. Model meaning of fluoroplastic alloy centrifugal pump
50FSB-30DL
50 represents the diameter of the suction port (mm)
FS means that the material of the parts in contact with the medium is fluoroplastics
B stands for single-stage single-suction cantilever centrifugal pump
30 represents the head (m)
D stands for short bracket connection type

L stands for shaft connection (with bottom plate)

3. Product features of fluoroplastic alloy centrifugal pump:
Fluoroplastic alloy pump is composed of pump body, impeller, closure, seal, bracket, pump shaft, coupling, lifting bolt, nut, bottom plate and so on.
1. Pump body: One steel flange ring is embedded in the connecting department on the left and right sides, and one is molded into plastic alloy. It has the advantages of compact and reasonable structure, strong corrosion resistance, tight and reliable sealing function, stable operation, low noise, high mechanical strength, non-aging, simple decomposition, convenient maintenance, smooth flow channel, high efficiency, and energy saving.
2. A piece of stainless steel (1Cr18Ni9Ti) pressed plastic alloy is embedded in the right side of the gland.
3. Impeller: the shaft connection method is adopted. The metal shaft is processed by steel round and then outsourcing fluorine plastic to be formed by high-temperature compression molding, so that the impeller and the metal shaft are firmly integrated to ensure that the shaft root and the rear of the impeller bear the torque force during rotation. , So the medium flow part is plastic alloy.

4. Mechanical seal: Adopt WB2 type and ST type adjustable single-end mechanical seal technology without cooling water, made of silicon carbide, high-purity alumina ceramics, filled with tetrafluoroethylene, graphite and other materials.
