New C-Series air-operated double-diaphragm (AODD) pumps (photo) are designed to enable the housing parts to be tightened to each other via housing bolts. Rather than using single bolts that press against the housing, all of the C-Series’ bolts are tightened together against a diaphragm-sized ring on each side of the pump. This design distributes the forces of the housing bolts onto the housing parts evenly, providing a consistent flow of forces that increases bolt torque and improves pump safety. The design of C-Series pumps also ensures the suction and discharge ports are available as separate housing parts so that different connection versions are available for compatibility with existing installations. In addition, these pumps provide good suction head, and feature self-priming and dry-run capabilities. The C-Series also features no mechanical seals, drives or rotating parts that cause wear over time. C-Series pumps are available in three pump sizes and achieve flowrates ranging from from 1.3 to 7 m3/h at a maximum discharge pressure of 7 bars (100 psig). — Almatec Maschinenbau GmbH, Kamp-Lintfort, Germany
