  • HPO Piston Seals - HPO
HPO Piston Seals
Model - HPO
Product Description
The HPO Piston Seals are a combination seal made of a PTFE profile ring and an O-Ring energizer. The PTFE seal has low friction characteristics which make it perfect for reducing energy loss and increasing the service life of the mechanism. Since the PTFE profile ring has a wide operating temperature range, the seal’s operating temperature range can be suitably adjusted by choosing an optimum O-Ring material. Thus providing a wide temperature range for the Seal. While similar to an HOD Piston Seal, the HPO Piston Seal can save installation space, while still being able to maintain a tight seal for a high-speed, high pressure, double acting environment.

Product Description The UOP Piston Seal is a single acting, U-cup piston seal with an asymmetrical design. The seal can be in a double-acting cylinder by using two seals in a back-to-back arrangement. The outer diameter of the seal has a shortened lip which increases the cross-sectional area. This seal is both an excellent dynamic as well as static seal. It can withstand pressures of up to 40Mpa considering a smaller extrusion gap. The UOP Piston Seal is mostly used in construction and earth-moving machinery. Material Polyurethane Product Advantages Good media resistance Excellent wear resistance Wide operating temperature range Very good static and dynamic tightness Application Earth-moving machinery, construction machinery, agricultural equipment, injection molding machines, fork-lifts, loading platforms and standard cylinders.

Product Description The COP Piston Seal is a single acting U-cup seal. Its inner diameter is designed to create a tight seal, while its shortened outer diameter is designed to reduce friction. The cross-section due to the shortened lip is smaller, but it still provides very strong sealing. The COP Piston Seal can withstand maximum pressures of up to 30Mpa. This kind of seal is perfect for forklifts, mold injection machines, agricultural equipment etc. Material Polyurethane Product Advantages Good media resistance Excellent wear resistance Wide operating temperature range Very good static and dynamic tightness Easier installation.

Product Description The HOD Piston Seal is a four-piece combination seal used in heavy-duty hydraulic cylinders. The primary PTFE seal is made of low-friction materials which is perfect for the high-speed and high pressure hydraulic cylinder application. The HOD Piston Seal is a double acting seal and is supported by nylon back-up rings on either side to allow sealing and protect the main PTFE profile from high pressures on both sides of the piston. Together, this combination seal can withstand pressures of up to 50Mpa. The HOD Piston Seal is mostly used in mining equipment, construction machinery and high-speed hydraulic cylinders. Material NBR Nylon Friction Ring -PTFE Product Advantages Excellent media resistance in case of suitable compound selection Excellent gap extrusion resistance Very good dynamic tightness even with pressure peaks High-speed sliding Application Mining equipment, Earth-moving machinery and construction machinery Operating Conditions Media Mineral oils Pressure ≦50 Mpa Speed ≦1.5 m/s Temperature Range -40°C , +100°C Gap Dimension 510 Bar 650 Bar 800 Bar 1 mm 0.45 mm 0.19 mm Surface Roughness   Sliding Surface Groove Base Groove Flanks Ra 0.1~0.8 µm ≦1.6 µm ≦3.2 µm Rz 0.4~3.2 µm ≦6.3 µm ≦12.5 µm

Product Description The HPS Piston Seal is a PTFE seal combined with a square seals energizers. The low-friction characteristics of PTFE combined with the performance abilities of the square seals make it able to provide a strong and efficient seal. The square seals design provides a robust sealing as it is less likely to slide or roll in the groove under the high speed and pressure of a double acting cylinder. Material Square Ring-NBR Friction Ring -PTFE Product Advantages Good media resistance Low frictional resistance Wide operating temperature range depending on the Square Ring material Very good static and dynamic tightness High-speed sliding Fit small grooves heights Application Agricultural equipment, injection molding machines, fork-lifts and loading platforms Operating Conditions Media Mineral oils Pressure ≦35 Mpa Speed ≦1.5 m/s Temperature Range -40°C , +100°C Gap Dimension 140 Bar 210 Bar 350 Bar 0.6 mm 0.6 mm 0.23 mm Surface Roughness   Sliding Surface Groove Base Groove Flanks Ra 0.1~0.8 µm ≦1.6 µm ≦3.2 µm Rz 0.4~3.2 µm ≦6.3 µm ≦12.5 µm
