Diaphragm pumps have had quite the evolution over the last few years with new innovations in diaphragm materials, pump body engineering, drive systems and overall design. This evolution is mainly end user driven; more facilities face budget constraints and have thus demanded cost effective solutions for transferring wastewater and slurry (which diaphragm pumps have traditionally offered). Diaphragm pump manufacturers have responded by offering heavy duty pump models that transcend their usual application capabilities and now may be suitable for areas that submersible pumps and trash pumps once dominated. Here’s a partial answer to how this evolution has happened:
What’s New in Diaphragm Pumps?
What Commercial Marine Operators Should Consider Under MARPOL ANNEX 5
Commercial marine operators around the world should understand that the Marpol Annex five prohibits the disposal of cooking oil, slurries and other substances which may be considered toxic to the marine environment. All of these substances are no longer permitted to be dumped at sea no matter how far offshore.
Marina Pump Outs and The New MARPOL Annex V
As many marinas know, the new MARPOL Annex 5 which prohibits disposal of garbage from ships, yachts and boats (which includes certain types of wastewater) have come into effect as of January 1, 2013. The new regulations set specific requirements for disposing of black water, cooking oil, grey water, residues, liquid detergents and animal waste.
