[Three rain valve to recommend the star product - Mechanical seal]: 1, during installation, dismantling the mechanical seal carefully, prohibited the use of hand-hammer and flat shovel 109-110 mechanical seal to avoid damage to the sealing element. If less than the time scale demolition, should be cleaned before the demolition. 2, if both ends of the pump mechanical seal, in the assembly, disassembly process to take care of each other, to prevent a loss. 3, for the run-off of mechanical seals, where a loose gland seal moves in the case, the static ring parts must be replaced, should continue to be used to re-tighten. Because friction original tracks changes will happen after running loose, sealing contact surfaces easily damaged. [Three rain valve to recommend the star product - Mechanical seal] Introduction: HG9 type mechanical seals are single face 109-80 mechanical seal, unbalanced rubber bellows structure, HG9 type mechanical seal its compliance with DIN24960 standard G60, G50 in line with European 109-100 standard mechanical seal, G55 meet US standards mechanical seal, its floating regulation performance, can enhance or reduce the number of turns of the spring, to accommodate axial installation requirements, simple structure, easy installation, good performance, is the international authority of the pump factory authorized, welcomed by users. Vice friction materials and auxiliary materials were selected according to the actual working conditions. Scope: Sealed Medium: cold water, hot water, beverages, weak acid weak base, with a variety of media particles.
