Almatec Plastic AODD Pumps with Solid Design

An important design element for Almatec® air-operated double-diaphragm (AODD) pumps is a solid-block construction, which is necessary to support the weight of an oscillating pump. With this design, the individual components can be designed so that the required wall thicknesses are arranged where needed. The high-static mass leads to a smooth operation and eliminates the need for unnecessary external metal parts that otherwise would be used for reinforcement. The mechanical machining of a solid plastic block is also economical thanks to modern CNC technology that enables tight tolerances to be achieved. In all Almatec plastic pumps, only German-produced virgin PE and PTFE is used.
