The new E-Series Plastic AODD (air-operated double diaphragm) pumps feature no mechanical seals or packing, thereby eliminating a critical leak point. Instead, these pumps have a stainless-steel containment ring that creates consistent high-torque compression all the way around the ring, pulling the components tighter together and eliminating a potential leak path. Due to its metal core, the E-Series does not require diaphragm discs, which frequently give rise to leaks and attract contaminants. The E-Series is available in seven sizes from 6 to 76 mm, with maximum flows to 800 L/min and heads of 5 m dry (9.5 m wet). The pumps handle temperatures to 120°C and a maximum solids size of up to 15 mm. — Almatec Machinenbau GmbH, Kamp-Lintfort, Germany
