Lepu Seal - A Professional China Mechanical Seal Manufacturer providing Cartridge Seal, Grundfos Mechanical Seal And We offer free sample!
Product Introduction
The LP-491 mechanical seal represents a high-performance sealing solution engineered for short installation space requirements, delivering full compliance with EN 12756 standards. As a direct replacement and upgrade for Chesterton 491 models, its innovative design positions the dynamic O-ring on a replaceable component surface, completely eliminating shaft/sleeve damage and fretting issues while significantly extending equipment service life.
Featuring a balanced, high-pressure monolithic construction, this seal provides superior performance over original equipment components while maintaining compact dimensions. The integral seal ring design ensures stable operation under pressures ≤1.6MPa, with bellows compensation mechanisms accommodating ±0.8mm axial movement - particularly suitable for high-vibration rotating equipment. All wearing components utilize modular designs that support field replacement using low-cost rebuild kits, dramatically reducing maintenance time and labor expenses.
● Lepu Seal mechanical seal manufacturer & supplier can provide OEM service.
● We are a mechanical seal manufacturer with 25 years of production experience since 1998 in China.

Standard configurations offer multiple material combinations: Stationary/rotary rings available in silicon carbide/silicon carbide or tungsten carbide/carbon graphite pairs; metal components crafted from electrolytically polished 316L stainless steel; elastomers standard with FKM, with EPDM or FFKM options for extreme conditions. Installation dimensions are fully compatible with original equipment, enabling direct replacement without equipment modification.
The LP-491 has been widely adopted in chemical process pumps, boiler feed pumps, and pharmaceutical mixing equipment, demonstrating exceptional performance in temperatures from -20℃ to 180℃ at speeds ≤15m/s. We provide comprehensive support including installation guidance, maintenance training, and technical assistance to ensure optimal customer experience.
