Maintaining an Equilibar Back Pressure Regulator

MAINTENANCE NOTES

Equilibar recommends the following for improved product longevity and performance:

  • Maintain a strainer or filter upstream of the back pressure regulator.
  • Conduct an annual inspection of the diaphragm integrity, especially for applications where there is strong or regular pulsing (i.e. reciprocating pump, etc.). Increased inspection frequency may be necessary for extreme condition applications.
  • After inspection, it is recommended to clean the regulator prior to reassembly. (Follow assembly instructions in the Installation & Maintenance Guide shipped with the product, or download the Installation & Maintenance Guide from our website).

REPLACEMENT PARTS

It is recommended to order spare parts prior to performing maintenance. The following replacement part kits are available for order:

  • RBK – Rebuild Kits – replacement parts for O-rings AND diaphragms
  • DI – Diaphragm Kit – replacement parts for diaphragms only
  • OR – O-ring Kit – replacement parts for the O-rings only

Special product circumstances

  • The Ultra Low Flow UxL Series and The Zero Flow ZF back pressure regulators have extra internal parts that may need to be replaced on an infrequent basis.

Contact an application engineer to discuss what type of replacement parts you require.

REBUILD INSTRUCTIONAL VIDEOS

The video below demonstrates how simple it is to rebuild an Equilibar back pressure regulator. The regulator in this video is a research series back pressure regulator, but the process is similar for our GS series back pressure regulators.


The UxL back pressure regulator has a different design, so the rebuild instructions include an additional step. The video below demonstrates how to replace a “removable seat” in a UxL back pressure regulator.

The ZF back pressure regulator also has a different design with additional steps. The video below demonstrates how to rebuild a ZF back pressure regulator.
