Powered by compressed air, this high-pressure AODD pump can deliver discharge pressures up to 250 PSI (17 bar), making it suitable for filter press feed, high-pressure transfer, and critical industrial fluid handling applications.\u003c\/p\u003e\n\u003cp\u003eEngineered with a 2:1 pressure ratio, the EH2-M pump is built with bolted metallic construction, weighted check balls, and metallic seats to support durable valve sealing in high-pressure service. Its balanced diaphragm design helps reduce pressure differential across the diaphragm, supporting longer parts life, reduced downtime, and lower total cost of ownership.\u003c\/p\u003e\n\u003cp\u003eThe EH2-M is available in cast iron and 316 stainless steel construction with various diaphragm options, giving users flexibility for different fluid compatibility and industrial operating requirements.\u003c\/p\u003e\n\u003ch3 style=\"color: #263879;
