HM12-Mechanical Seal for Anti – Reverse Pressure Light Hydrocarbon Pumps

没有此类产品
产品描述

 

Design Features:

  • Conform to API 682 Standard;
  • Multi – spring, O - ring, pushed mechanical seal design;
  • Mostly used as the inner seal of unpressurized or pressurized FB combination (commonly known as tandem arrangement);
  • Special structure design of primary ring and mating ring makes it can bear both external pressure and internal pressure;
  • The structure of finite element optimization design makes the coordination and control of heat and pressure deformation optimal, and the high quality materials selected for friction pair make the sealing effect of narrow end face reach the best;
  • Precision lapping sealing ring with high finish and excellent flatness;
  • Single arrangement can meet the requirements of fuel escape control; but with a dual arrangement, it is more secure and reliable (recommended);
  • With a dual seal arrangement, the outer seal is often using the compact universal mechanical seal HM13 type;
  • Simple and reliable structure, easy to install and disassemble.

Performance Capability:

  • Shaft diameter: 20-150mm;
  • Temperature: -40℃-260℃;
  • Pressure: external pressure up to 6.8mpa, internal pressure up to 5.2mpa;
  • Speed: 0-25 m/s;
  • Media: volatile organic compounds and hazardous multiphase media; lubricants, aqueous solutions, chemicals, light hydrocarbon compounds and certain acids, etc.
   

Application:

Applicable to petrochemical and natural gas, chemical, food, pharmaceutical and other industries.
