The redundant seal lips enable this seal to handle higher pressure and create additional sealing capabilities, especially under flooded conditions. The high temperature and high pressure mechanical seal produced by our company can be used to seal oil, water, weak base, weak acid, flammable, explosive, and toxic gases, propylene, toluene, potassium … For dirty, dusty or polluted environments, our ASHP5 style with additional…, Supreme medium-pressure double-lip oil seal. Mechanical seal for nissin pump. Most products (process fluids) that are sealed are not very clean. Materials: NBR (Nitrile), FKM, Viton®, HNBR, EPDM, SIL, CR, ACM, VMQ, PTFE, low-temperature material grades and FDA-compliant grades. Ultrahigh pressure single-lip rotary shaft seal for extreme environments. For dirty, dusty or polluted environments, our R2HP1 style with additional dust lip should be used. The one-piece elastomer design makes it easier to fit in multi-port units than traditional PTFE-based seals. This seal is able to accommodate press-in fitment in housings with short axial length. It looks like your browser does not have JavaScript enabled. Flanged V-Spring-loaded high-pressure rotary shaft seal. The soft OD eliminates damage to housings manufactured from expensive metals, and the integrated O-ring on the OD of the seal serves as an anti-rotation device and maximizes static sealing between the seal and the bore. Small quantities are available in 1 to 3 days. The thermoplastic reinforced design ensures concentric fitment and increased corrosion resistance over traditional seals. Application-specific and proprietary seal designs are available. Symbols A Area of sliding face A H Area hydraulically loaded by medium pressure … Bi-directional High-Pressure Rotary Seals- capable of sealing pressure from both sides, Small cross-section low-friction internal swivel seal. This seal is designed to retrofit O-ring glands, to minimize system friction, and to provide a positive seal on the rod. High Pressure, Heavy Duty Seal, Single Acting, Independent of Direction of Rotation. – up to 500psi (35bar)*; PV-Rating 5.0 to 9.0. The wave … The rubber OD provides better static sealing. Packing Although mechanical seals had been around for many decades, by 1955 industry had converted only a small percentage of pumps from packing to mechanical seals. Fits in the same hardware pocket as SB40 Style. Small quantities are available in 1 to 3 days. Hydropad designs are useful in high-pressure applications—​where pressure has a tendency to distort the seal faces and where the face velocity increases heat generation and in sealing fluids that have poor lubrication properties. The thermoplastic or optional metal reinforced design ensures concentric fitment and increased corrosion resistance over traditional seals. Bellows Seal. This seal provides excellent positive sealing and fluid separation, much superior to PTFE seals. A retaining device is recommended to hold the seal in place under pressures above *psi. The dynamic seal lip is made of a premium low-friction Duralast™ material to reduce friction, heat build-up, and wear. This design creates very low parasitic friction under load and adds much lower heat generation than most seal designs. This seal is for high PV applications characterized by high pressure and low speed. As a result of growth in excess of 20% per year, AES Seal has become the only major international new entrant to the mechanical seal … Up to 3,500*psi. Leakage control of medium to high pressure on rotary equipment is one of the most challenging sealing applications. More Info Under higher pressure, the sliding contact area between the seal lip and the shaft will generate much higher friction, heat and wear of the seal lip than under zero system pressure, causing premature or catastrophic seal failure in a very short period of time when using rotary seals … Elastomer Bellow Shaft Seals. Many early mechanical seal designs placed the spring inside the process fluid. This seal has a relatively small footprint and is available in many materials specially suited to handle aggressive chemicals and environments. End face seals depend upon the constant flatness and … Under higher pressure, the sliding contact area between the seal lip and the shaft will generate much higher friction, heat and wear of the seal lip than under zero system pressure, causing premature or catastrophic seal failure in a very short period of time when using rotary seals not specifically designed for higher pressures. Metal Bellows. AES Seals are also mechanical seals that are used in pumps and rotating equipment to prevent liquids and gases from escaping into the environment. The design is an O-ring energizing a wear-resistant PTFE cap. The rubber-covered OD of the seal creates a tight seal with the housing bore. High-pressure, low-speed external rotary/swivel seal.
