Mechanical Seals Styles 73P and 75P

DUAL STATIONARY TANDEM CARTRIDGE SEALS

MECHANICAL SEALS STYLES 73P AND 75P

Dual cartridge seals are the answer for applications where a second level of protection is needed. Flex-A-Seal’s Styles 73P and 75P offer system and personnel protection and are designed to ensure compliance with stringent environmental and emissions regulations.

Features

  • The Style 73P offers the advantages of an inboard stationary metal bellows design, while the Style 75P offers the efficiency and economy of springs isolated from the product
  • Easy installation and low maintenance that can be operated in a pressurized or non-pressurized state
  • Both the 73P and 75P can fit pumps with standard and enlarged bores without modification
  • Flex-A-Seal has replaced traditional cup point set screws with stainless steel drive lugs, resulting in a five-fold improvement in torque transmission strength. And the possibility of sleeve distortion and damage due to over-tightened set screws is eliminated
  • Both cartridge seal designs are hydraulically balanced
