Secondary Wiper Seal Component – Food Manufacturing

Component Specifications

Definition

A secondary sealing component in meat processing vacuum pump assemblies designed to remove residual contaminants and provide additional sealing protection. It functions as a backup to primary seals, preventing fluid ingress and maintaining vacuum integrity in hygienic food processing environments.

Working Principle

Operates through mechanical wiping action against rotating or reciprocating surfaces, removing debris and fluids while creating a secondary barrier. Works in conjunction with primary seals to maintain vacuum pressure and prevent contamination in meat processing applications.

Materials

FDA-compliant materials: Nitrile rubber (NBR), Ethylene Propylene Diene Monomer (EPDM), or Fluorocarbon (FKM/Viton) with food-grade certifications. Shore hardness: 70-90A. Temperature range: -40°C to 150°C.

Technical Parameters

Speed Up to 10 m/s
Cross Section 3-8 mm
FDA Compliance Yes
Inner Diameter 25-150 mm
Temperature Range -40°C to 150°C
Operating Pressure Up to 1 bar
EU 10/2011 Compliance Yes

Standards

ISO 3601-1, DIN 3760, FDA 21 CFR 177.2600, EU 10/2011

Frequently Asked Questions

What is the main function of a secondary wiper seal in meat processing vacuum pumps?

The secondary wiper seal serves as a backup protection system that removes residual contaminants and provides additional sealing security, preventing fluid ingress and maintaining vacuum integrity in hygienic meat processing environments.

What materials are suitable for secondary wiper seals in food processing applications?

FDA-compliant materials including Nitrile rubber (NBR), EPDM, or Fluorocarbon (FKM/Viton) with appropriate food-grade certifications and resistance to cleaning chemicals used in meat processing facilities.

How does the secondary wiper seal differ from primary seals in vacuum pump assemblies?

While primary seals handle the main sealing function under operating conditions, secondary wiper seals provide additional protection by wiping away contaminants and acting as a backup barrier against fluid ingress and vacuum loss.
