HDPS and DESMOPAN diaphragms are old news and old technology. That is why AR developed the Blueflex diaphragm for AR pumps:
Exact same dimensions as the black HDPS and clear DESMOPAN versions, just better quality!
Replaces AR550086 diaphragms
- AR BHS90
- AR BHS105
- AR BHS120
Blueflex diaphragms can be fitted in older diaphragms pumps and replace the HDPS versions. Harder wearing and longer life.
