Almatec E-series AOD Pumps Features
Construction and Materials
The exterior of Almatec pumps are free of metal as only a solid plastic body can support the necessary weight for an oscillating pump. The individual components can be designed, so that the required wall thicknesses are arranged where they are needed. The mechanical machining of a solid plastic block is economical thanks to modern CNC technology, enabling tight tolerances to be achieved. The high static mass leads to a smooth operation and external metal parts for reinforcement are not necessary. Only virgin PE and PTFE, without additives, are used. Almatex AOD pumps are produced in Germany.
The pumps of the E-Series are available in different materials:
- Housing: PE, PE conductive, PTFE, PTFE conductive
- Diaphragms: EPDM, PTFE/EPDM compound, PTFE modified, NBR, ATEX variations
- Ball valves: EPDM, PTFE, NBR, stainless steel
- Cylinder valves: PTFE
