PEEK Balance Disc Seal
Core Summary: The PEEK balance disc seal manufactured by Dalian Allstar Material is a core component for multistage centrifugal pumps and compressors, achieving automatic compensation of rotor axial forces through precise differential pressure control. Utilizing the independently developed special material, this product significantly improves equipment volumetric efficiency and substantially extends the overall operation cycle.
Key Product Advantages:
-
Innovative Material & Structure: Features the independently developed labyrinth seal special material, combined with an optimized tooth structure design.
-
High-Efficiency Sealing: Compared to traditional aluminum alloy seals, it reduces the sealing clearance by 40-60%, effectively improving equipment volumetric efficiency by 2-5%.
-
Superior Physical Durability: Offers excellent self-lubricating properties and impact resistance. The teeth will not permanently deform upon contacting the shaft, and it can withstand continuous working temperatures up to 260℃.
-
Cost Reduction & Extended Lifespan: Significantly reduces routine maintenance frequency, extending the stable equipment operation cycle to over 18,000 hours.
PEEK Bushing
Dalian Allstar's precision-machined PEEK bushings provide reliable, self-lubricating support for rotating or reciprocating shafts, significantly reducing friction and wear.
Key Advantages:
-
High Precision: Strict tolerance control of ±0.010-0.025mm and inner bore surface roughness of Ra≤0.4μm.
-
Superior Performance: Low friction coefficient (0.08-0.15) and high PV value up to 3.5MPa·m/s, allowing extended operation without external lubrication.
-
Extreme Durability: Withstands continuous working temperatures up to 260℃ and resists over 200+ chemical media.
-
Extended Lifespan: Lasts 3-5 times longer than traditional bronze bushings across gear pumps, hydraulic, food, and semiconductor machinery.
PEEK Labyrinth Seal
PEEK labyrinth seals are non-contact dynamic sealing devices that restrict medium leakage in high-speed rotating equipment by utilizing a specific tooth profile to dissipate fluid energy. Compared to traditional metal seals, PEEK allows for significantly tighter clearances, effectively minimizing leakage and extending overall service life.
Key Advantages:
-
Precision Clearance Control: Enables small radial clearances of 0.08-0.50mm (40-50% smaller than aluminum alloy), directly reducing leakage rates by 30-60%.
-
Extreme Temperature Resistance: Withstands continuous operating temperatures up to 260°C and short-term exposure up to 300°C.
-
Durability & Stability: Sustains minimal wear during transient contact without clearance enlargement, and offers robust chemical resistance to acids, alkalis, and organic solvents.
-
Lightweight & Extended Lifespan: Features a low density of 1.32g/cm³ to reduce rotor load, while delivering a service life 2-3 times longer than metal labyrinth seals.
PEEK Wear Ring
Dalian Allstar's high-purity PEEK wear rings control internal leakage and significantly boost pump efficiency with tighter clearances than traditional metal rings.
Key Advantages:
-
High Precision: Strict dimensional tolerance of ±0.015mm and surface roughness of Ra≤0.4μm.
-
Enhanced Efficiency: Reduces internal leakage by 35-50% and improves overall pump efficiency by 3-7%.
-
Extreme Durability: Low friction coefficient (0.08-0.15), resists dry friction damage, and withstands continuous temperatures up to 260℃.
-
Extended Lifespan: Lasts 2-4 times longer than metal alternatives across chemical, petroleum, and power sectors.
