MOR LP-D Dual Cartridge Mechanical Seal

: 316L, duplex stainless steel (2205/2507), or Alloy C276 for high corrosion resistance

: 316L or Hastelloy C276, isolated from process fluid to prevent fouling

MOR LP-D Dual Cartridge Mechanical Seal a cartridge-mounted, dual-face, back-to-back balanced mechanical seal, engineered to meet API 682 (Arrangement 3) standards for critical process pumps handling hazardous, toxic, flammable, or volatile fluids. It features a fully pre-assembled cartridge design for reliable, zero-leakage sealing in demanding refinery, petrochemical, and chemical applications.

: Pre-assembled and preset as a complete unit, eliminating on-site measurement and alignment errors, enabling quick installation and replacement without pump disassembly.

Dual-Face Back-to-Back Structure: Forms a sealed barrier chamber for pressurized barrier fluid, ensuring zero leakage of hazardous media to the atmosphere.

: Reduces seal face loading and heat generation, extending service life in medium-to-high pressure applications.

: Multi-springs and secondary seals are located outside the process fluid, preventing clogging and wear in abrasive or crystallizing services.

: Protects the pump shaft from wear, corrosion, and high-speed abrasion.

: No need to distinguish rotation direction during installation.

: Optimized for API Plans 53A, 53B, 53C, and 54 barrier fluid systems.

: Dual-face design and pressurized barrier fluid ensure compliance with strict environmental and safety regulations.

: Balanced design and high-grade materials reduce wear and extend maintenance intervals.

: Cartridge design minimizes installation time and eliminates alignment errors, reducing downtime.

: Isolated springs and dynamic seals prevent clogging in abrasive, crystallizing, or particle-laden fluids.

: Direct replacement for international OEM seals and compatible with API 610 centrifugal pumps.
