Equipped with cooling circulation flushing system, can adapt to a wider temperature range and more complex media. Sealing ring and matrix structure provide a variety of material choice, can adapt to a variety of corrosive media. Applicable industries: paper and paper products industry, chemical raw materials and chemical products industry, pharmaceutical manufacturing industry, ferrous metal smelting, non-ferrous metal smelting.

Mechanical seal for SLZB slurry pump

Shandong double-wheel solid-liquid two-phase flow slurry pump, speed: n=580 ~ 1485r/min, working pressure: pump working pressure is 1.6Mpa and 2.5Mpa, of which 2.5Mpa has (SLZC 80 -- 630, SLZC 150 -- 980) two. Operating temperature: T ≤ 140°C, the proportion of solid particles <1.1 ~ 1.8t/m3, with strong abrasive, corrosive slurry media, the maximum volume concentration of the transport medium can reach 25%, the maximum weight concentration can reach 65 ~ 70%, the maximum conveying particle diameter can reach 60mm.

Mechanical seal for SLZC twin-wheel pump

Mechanical seal at the beginning of the start, because the axial string is too large, and often make the friction pair face pressure has a large increase or decrease, this is mainly because the axial string of mechanical seal spring compression increased or decreased, increase or reduce the spring pressure. The resulting increased specific pressure of the end face is one of the main reasons for the appearance of thermal cracks, gluing and serious wear during the end face driving. For this purpose, the axial stringer of the mechanical seal should be limited. Under normal conditions, the allowable axial stringer of the TJ-166/85 mechanical seal is plus or minus 0.5mm.

SLZC slurry pump mechanical seal

Installation method: slurry pump shaft with mechanical seal positioning seam allowance should be clean, coated with oil, and the mechanical seal screw pump shaft sleeve, pushed to the end, put on a 12 (o-ring), superior impeller, made out in about 30 ° above, evenly tighten 6 - M12 bolts, turning operation no touch, no brush, feel a slight laboring. Pressure test with cooling sealing fluid.

SLZB, SLZC solid-liquid two-phase flow slurry pump has a wide range of spectrum, reasonable structure, advanced hydraulic design, strong flow capacity, high efficiency, long life, high reliability, convenient, low operating cost, and other significant advantages, the flow parts adopt a new generation of high wear resistance, corrosion resistance material. It is widely used in electric power, metallurgy, mining, coal, building materials, chemical industry, shipping, port and other industrial sectors to transport all kinds of slag slurry containing strong abrasion and corrosion medium.
