THE АПГ-TYPE SPRING-LOADED HYDRAULIC ACCUMULATORS

The АПГ-type spring-loaded hydraulic accumulators are designed for creation of the hydraulic lock in the double end seal of centrifugal pumps.

The accumulators are installed in the separate circulation loop for the sealing liquid and provide the pressure of the sealing liquid (up to 6 MPa), which is higher that the pressure of the pumped liquid before the end seal, as well as ensure cooling of the sealing liquid and automatic replenishment of the sealing liquid circulation loop from feeding pipeline.

The accumulators are produced in the following makes:

of carbon steel — АПГ-1С;

of stainless steel — АПГ-1К.
