[Three rain valve to recommend the star product - Mechanical seal] Introduction: HU21 mechanical seal CRK mechanical seal, the main face of all kinds of pipeline pumps, sewage pump, water pump, submersible pumps and other conditions very bad media, Its installation size is short, the balance factor, can replace a variety of light mechanical seals: 502,2100 Crane, Burgmann MG1, domestic 109, BIA, FBD and other mechanical seals, which rely on rubber drive card drive, drive fork, effective avoid failure and aging speed rubber bellows. Scope: Sealed Medium: Oil, water, and other general corrosive liquids. Seal chamber pressure: ≤0.6Mpa sealed chamber temperature: -40 ℃ ~ 120 ℃ line speed: ≤15m / s [three rain valve to recommend the star product - Mechanical seal] Introduction: Advantages a reliable sealing in a long period of operation, the sealed state is very stable, very small amount of leakage CDLF2-40 mechanical seal, according to rough statistics CDLA-22 mechanical seal, the leakage is typically only 1/100 of soft packing seal; 2, long life in oil, water class media generally up to 1 to 2 years or longer mechanical seal, usually in the chemical medium can reach more than six months; 3, friction power consumption is small mechanical seal friction power is only soft packing 10% to 50% ; 4, the shaft or sleeve essentially from wear and tear; 5, after a long maintenance cycle can automatically compensate for face wear, under normal circumstances, no need regular maintenance; CDLA-22 mechanical seal mechanical seal _ _ Ankang Grundfos machine Three letters selected by rain, rain Valve Co., Ltd., Tianjin.
