brief introduction

SJBThe series of acid resistant and wear-resistant pumps is a single-stage single suction centrifugal pump developed by Yamei Pump Industry by introducing, digesting, and absorbing advanced German technology, combined with domestic production needs , in accordance withGB/T5656Standard.

SJBThe overcurrent components of the acid resistant and wear-resistant pump, such as the pump body, impeller, and pump cover, are made of non-metallic materials with high mechanical strength, good wear resistance, and corrosion resistance, and are molded at high temperature and high pressure in one go. The shell is made of high-quality materials that are resistant to compression and impactA3Made of steel casting. The pump uses an internal mechanical seal, and the material of the mechanical seal surface is currently excellent corrosion-resistant and wear-resistant pressureless sintered silicon carbide, combined with high-quality“O”Type sealing ring, with special sealing system technology and long service life. The impeller is single suction, radial, semi open (imported)DN150The above models are enclosed, and the dynamic balance meets the requirementsISO G6.3.

Application scope

Yamei Pump Industry'sSJBThe application range of acid resistant and wear-resistant pumps is very wide.

Transport medium: solid content lower than40%(Volume ratio), temperature below150℃A highly corrosive medium that varies depending on the material.

Chemical industryTransportation and circulation of various acids, alkalis, salts, organic chemicals, and corrosive slurries.

Acid washing industryAcid circulation pumps and waste acid pumps, including stainless steel mixed acid pickling (hydrofluoric acid mixed with nitric acid, hydrofluoric acid mixed with sulfuric acid, and others), carbon steel plate hydrochloric acid pickling, titanium plate and other metal plate pickling.

Acid regeneration industryWaste acid conveying pump, acid supply pump, and acid circulation pump in the middle.

Oxidation industryThe oxidation circulation pump, sealing circulation pump, coloring circulation pump, and soup washing circulation pump used for aluminum oxidation.

Desulfurization industryThe slurry circulation pump used for ammonia desulfurization, magnesium oxide desulfurization, etc.

Other corrosive slurries.
