Product Detailed Description

YALAN WB2 (Type 152) PTFE Bellow Mechanical Seal for Acid Proof Pumps, Plastic Pumps, Alkali Pumps, and Vacuum Equipment

Structural Features: single end, balanced, independent direction of rotation, PTFE bellow, bellow transmission, external type mechanical seal. This component is easy to install. The bellow provides pressure compensation to the sealing faces. The bellow design can prevent radial runout so the floatability of the rotary ring is increased.

Industrial Standards: JB/T7372-94

Scopes of Application: widely used in acid proof pumps, plastic pumps, alkali pumps, vacuum equipment and other rotary devices.

Operation Parameters:

  • Pressure: 0.6 MPa or less
  • Temperature: -20 to 120 ºC
  • Linear Speed: 10 m/s or less

Materials:

  • Rotary Ring: Filled PTFE (Teflon)/SiC
  • Stationary Ring: Al2O2/SiC/Carbon
  • Elastomers: PTFE
  • Metal Parts: SS304/SS316

Mediums: sulfuric acid hydrocarbon acid, phosphoric acid, acetic acid, and nitric acid With various degrees, etc.

Customization: Changes of materials for getting other operating parameters are possible. Contact us with your requirements.
