), shut down the equipment, investigate and remove the cause. The seal is tailored to the conical installation space of the pump and perfectly suitable for solids-laden fluids. Combined with a single KSB 4HL mechanical seal this is an optimum sealing solution for demanding fluids. Barrier fluid must flood dual seals at all times during equipment operation. Locate the gland(s) against the face of the seal chamber. Orient the connections on the seal gland(s) as indicated by the seal assembly drawing. Avoid inadvertent operation of valves located in the cooling system that might result in shutting off the cooling flow. Other setting aids such as spacer rings may be indicated on the assembly drawing. Keep the mechanical seal in its original container until ready for installation. To ease installation, gaskets may be lightly lubricated. Cartridge seals unitize the complete seal assembly on a sleeve such that the entire seal is installed simultaneously. There are primarily 2 types of Seals … Make adjustments as necessary. The... Closed pressurised barrier fluid system compliant with all requirements of API 682, 4th edition*.

From mechanical seal installation to failure analysis, Chesterton offers a wide range of specialized field services to optimize your plant's performance as well as increase efficiency and reliability. For sleeve type bearings, refer to manufacturer instructions. For use in waste water, boiler feed, and compressor pumps, these seals have an extra-long spring that accommodates variations in seal cavity length. Single mechanical seal, bi-directional and balanced. Cut the plumbing. a pump shaft against a pump casing. They also help reduce the risk of seal damage during installation, which would inevitably lead to unwanted leakage and unscheduled … Double cartridge seal, bi-directional and balanced. Thermosyphon system compliant with all requirements of API 682, 4th edition*. 2. This allows for a shaft to spin, while a seal is being maintained mechanically. Through each stage of the repair / rebuilding process the seal is tested to exceed manufacturer’s specifications. Single cartridge seal, bi-directional and balanced. KSB SE & Co. KGaA uses cookies to be able to optimally design and continually improve its web site. Vent casing and tubing of heat exchange (if applicable). After bringing the unit up to operating conditions (pressure and tempera- ture), recheck pump to driver alignment. Mechanical Seals Installation Procedure. Concentricity of the shaft to the seal chamber bore should be within 0,025 mm per 25 mm shaft diameter (.001" per 1" shaft diameter) to a maximum of 0,125 mm (.005") TIR. "Leak-Pack Engineering (I) Pvt Ltd" is engaged in the design, manufacture and installation of Mechanical Shaft Seals for corrosive, volatile, abrasive, precious, flammable fluids on Pumps, Agitator, Blenders, Reactors, Blowers, compressors, mixers, steam turbines and other rotary-motion equipment. The mechanical seal used in the water pump seal is one of the most effective ways of rotating mechanical seal. Single mechanical seal, bi-directional, tailored to the seal installation space and the submersible mixer‘s requirements. Seal chamber squareness to the shaft centreline should be within 0,015 mm per 25 mm seal chamber bore (.0005" per 1" seal chamber bore). The design is tailored to the cooled pump... Special bi-directional single mechanical seal. Sturdy and practical seal design. Generally 0,05 - 0,10 mm (.002” -.004”) will be applicable for ball or roller type bearings. For performing maintenance, the seal may have to be dismantled and reinstalled. Some mechanical seals are sensitive to direction of rotation. Single cartridge seal, bi-directional and balanced. Cut the plumbing tubes connected to the centrifugal pump. This Mechanical Seals Installation and Repair training course includes delivery of training content by a highly experienced professional from the relevant domain as well as self-participation and learning through role-plays, group activities and projects. The animation video describes a typical dismantling procedure of a mechanical seal. It is assumed that the installer is familiar with seals and certainly with the requirements of their plant for the successful use of mechanical seals. Single mechanical seal, specially developed for hot water applications, with hook sleeve and "thermal barrier". Shaft runout should not exceed 0,05 mm (.002”) TIR (Total Indicator Reading) at any point along the shaft for ball or roller type bearings. Finally, evenly torque the three assemblies … Without the right tool, it’s easy to damage or dis-tort the seal lip or case. Inspect surfaces under gaskets to ensure they are free from pits or scratches. If the disassembly method is not appropriate or is in improper use, mechanical seal after assembly not only can not achieve the purpose of sealing, but also damage the assembled sealing elements. Clean and inspect pump parts. 2 Shaft runout should be checked against the equipment manufacturer‘s specifications. Open valves to flood equipment with product. These custom-designed tools greatly simplify handling and ease installation, making the process quicker and more straightforward. Lack thereof can damage o-rings or rubber bellows on the seal, causing them to tear, or roll. De très nombreux exemples de phrases traduites contenant "seal installation" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. Appropriate environmental and plant safety regulations also must be met. “If installing or replacing a mechanical seal, you’re going to bolt the seal adapter plate to the pedestal, and you’re going to hand-tighten it on,” Bryant explains. Tightening mechanical seals. The single cartridge seal can be connected to all common API Plans, such as 01, 02, 11, 31, 32 + 51, 61 (62) and 23 + 51, 61 (62). Correct seal setting is important in the successful operation of a mechanical seal. Shaft endplay should not exceed 0,25 mm (.010”) TIR, regardless of thrust bearing type. The stationary seat must be inserted into the seal gland. Verify the smoothness of the seal chamber face for a good gasket joint. Seal faces are lapped so flat it is impossible for a liquid or gas to flow through them. Since this step happens during installation, GIW ships mechanical seals with the tabs in place. Component seals are assembled sequentially on the equipment and require careful measurements to properly locate and lock the rotating components relative to the stationary components. Thermosyphon system for use with pressurised barrier fluid or unpressurised buffer fluid (Plans 53A and 52). KLOZURE® is a global company with installations worldwide, solving demanding applications big and small. When measuring the setting or securing cartridge seals, always make sure the shaft is in the same position as when the equipment is operating (e.g. We believe the best way to service the end user is through our strategic alliances with distribu-tion partners. A mechanical seal is a device designed to seal a rotating shaft against a stationary housing, e.g. Prior to installation, wipe lapped surfaces clean with a lint free cloth and quick drying solvent. There are many options available, from petroleum jelly, to silicon grease, to special lubricants. including the effects of thermal growth or contraction of the shaft relative to the casing). The gland is tightened evenly so that the seal is compressed to it’s recommended length. where a rotating shaft passes through a stationary housing or … Because mechanical shaft seal failures are the number one cause of pump downtime, we decided to dedicate this column to mechanical seal basics. The axial spring force is evenly distributed over the entire circumference of the primary ring. Be sure to remove the plastic spacers. Once disconnected, you are free to set the pump on a table or … Ensure seal faces and joints are free of scratches, contamina- tion and other damage. This could result in reduced spring force and length. The precision of its own processing is relatively high, especially the dynamic, static ring. The mechanical seal comes in two main pieces: The piece on the left is fitted into the hole in the rear engine cover and the piece on the right fits into the back of the water pump impeller. This video provides a hands on demonstration of how to install the seal.
