Bladder accumulator seal & ring kits

For replacing worn “O”- rings and retention rings from our standard bladder accumulators and pulsation dampeners. Available for all metal apparatus sizes (U001 to U350) and for plastic apparatus sizes U001 to U100.

.

The kits include the following pieces (refer to layouts and photos):
.

♦ A rubber (NBR, EPDM, FKM, silicone, etc…, according to the rubber material of the bladder) “O”- ring (only for plastic apparatus from size U002 to U100 and for the size U350 metal one) (A).

♦ A retention ring, either in polypropylene (for all plastic accumulators / pulsation dampeners) or in carbon steel (B) (for all metal accumulators / pulsation dampeners except for the size U350).

The polypropylene retention ring comes in the shape of a piece of thin flexible plastic bar cut to measure to fit inside the retention ring groove in the body of the apparatus (for sizes U002 to U007) (C) and in the shape of three rigid plastic ring sections to be put together inside the retention ring groove (for sizes U010 to U100) (D).
