Regarding whether a safety valve should be installed on the outlet of the pneumatic diaphragm pump
Thread Content
In high-risk storage tank areas where solvent is transferred from portable tanks to storage tanks via hoses connected to pneumatic diaphragm pumps, is it necessary to install a safety valve at the outlet of the pneumatic diaphragm pump? Should the outlet of this safety valve be connected to the inlet side of the pump? Are there any relevant regulations or standard documents governing this? Thank you~~:handshake
It’s not just a matter of adding it; the amount is too large. The main issue is whether there are any relevant regulatory documents or similar things that need to be dealt with.
It’s not necessary. A pneumatic diaphragm pump will stop pumping when it is overpressured and cannot operate any longer.
