AHP Seals’ high-performance Rotaflon™ rotary shaft seals are designed for rotary applications where the operating conditions exceed the capabilities of elastomeric rubber lip seals, where extended seal life is required or where mechanical seals are too costly … Shaft misalignment and runout and pressure-induced component deformation are significant challenges when implementing high pressure rotary seals. Medium-pressure double-lip oil seal with integrated seal lip support, and proprietary blends of PTFE bonded onto the dynamic sealing lip. 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. The soft OD eliminates damage to housings, 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. This high-performance seal design incorporates a formed seal lip for low lip load and low friction and is capable of handling aggressive media, dry run, high surface speeds and low to medium pressures. High Pressure, Heavy Duty Seal, Single Acting, Independent of Direction of Rotation. This seal is designed to provide long service life and low friction for extreme service applications over a wide temperature range. Expediting service available. 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 … Maximum service life can be achieved by applying a suitable lubricant between the two sealing lips. Ultrahigh pressure single-lip rotary shaft seal for extreme environments. It is typically used to provide a low leak solution for hydrostatic transmissions and high-pressure rotary equipment. Most products (process fluids) that are sealed are not very clean. Seals can not be operated at their upper pressure and speed ratings at the same time. Multiple internal springs ensure these seals keep the sealing surfaces in contact in demanding applications, such as agricultural, chemical, and mining pumps. Heavy Duty MechanicalPump Shaft Seals. Premium medium-pressure double-lip oil seal, Medium-pressure double-lip oil seal with integrated steel reinforcement element. – Pumps, motors, compressors, machine tools, brakes, clutches, mixers and others. FAQ. The one-piece elastomer design makes it easier to fit in multi-port units than traditional PTFE-based seals. PV-Rating: 1.4 to 5.0 depending on seal design and material. An exceptional high temperature seal, the Chesterton180H Single Cartridge Seal uses an advanced hydropad geometry seal face that improves film formation between the mechanical seal faces and significantly enhances face lubricity. Your email will be reviewed within 1 hour and we will respond the same business day. The thermoplastic or optional metal reinforced design ensures concentric fitment and increased corrosion resistance over traditional seals. Seals can not be operated at their upper pressure and speed ratings at the same time. 1 failed on September 13, 1961, as evidenced by high seal leakage. Seals cannot be operated at their upper pressure and speed ratings at the same time. – up to 10,000psi (350bar)*; PV-Rating 6.0 to 10.0  A retaining device is recommended to hold the seal in place under pressures above *psi. The innovative high-pressure mechanical seal technology is suitable for every phase of CO 2-gas, liquid, and supercritical. Concentrate testing only on pressure spikes, or only at high system pressure. The one-piece elastomer design makes it easier to fit in multi-port units than traditional PTFE-based seals. – up to 3,500psi (240bar)*; PV-Rating 7.0 to 9.0   Elastomer Bellow Shaft Seals. Flexible lip design offers better shaft-following ability and reduced lip load over standard seal designs. A tight tolerance lip support ring ensures a flexible seal lip and enables this seal to operate at higher continuous operating pressure. This seal design incorporates an anti-extrusion and support ring for the seal lip making it capable of handling high pressures. Pressure… 50 Series high pressure mechanical seal Main crude oil transportation pumps - single and tandem Boiler feed water pumps - single Multi-phase pumps - double Flashing hydrocarbons under high pressure - … Three-piece high-pressure seal for swivels and rotary distributors. High Pressure Mechanical Seal has positive drive arrangement and sturdy construction making the seal suitable for high pressure application… Series 900B/CG is specially designed cartridge seal for pumps handling oil, water and other fluids which are being pumped at very high pressure. This seal style is able to operate efficiently in environments where the operating parameters vary over a wide range. For pressures exceeding 3,000psi (210bar), please  contact engineering. A high temperature seal also designed for high speed and pressure, External cooling requirements are not needed for most applications, eliminating support equipment, Advanced hydropad geometry minimizes seal facewear and distortion, Reduces the frictional seal face heat concerns common with standard contacting seal face designs, Hydropad geometry increases pressure velocity parameters over standard seal face designs, Compact cartridge design for easy and reliable installation, Use where external cooling is intermittent, limited, or unavailable, 711 mm (28") Hg Vacuum to 40 bar g (600 psig) outboard. It was originally designed for the enhanced oil recovery industry, … Please contact one of our experienced seal engineers to select the best seal for your application.
