Plastic AH Series High-Pressure AODD Pumps from Almatec (Kamp-Lintfort, Germany) have no drives, no rotating parts, and no rotary shaft seals. The pumps offer dry-run capability, good controllability, and a gasketless mechanical design. A compressible drive medium permits gentle product delivery with attenuated pressure peaks. The AH pumps are available in three sizes and all have a driving maximum pressure of 7 bar with an internal boost that can build delivery pressure to as high as 15 bar. Other built-in features are compact dimensions, easy start-up, a corrosion- and abrasion-proof housing, and heavy-duty diaphragms.
