Technical Specifications Overview
Dimensions: The document provides dimensions for three models of pneumatic diaphragm
pumps: AD 20, AD 32, and AD 50. The length, width, and height increase progressively with each model, with AD 20 being the smallest and AD 50 the largest.
Nominal Port Size: The nominal port sizes are R 3/4 for AD 20, R 1 1/4 for AD 32, and R 2 for AD 50, indicating the increasing capacity and flow rate capability.
Air Connection: All models have an air connection size of R 1/4, except for AD 50, which has R 1/2, suggesting a higher air flow requirement for the largest model.
Weight: The weight of the pumps varies significantly, with the AD 20 weighing 6 kg, AD 32 at 13 kg, and AD 50 at 29 kg, reflecting the increase in size and capacity.
Max. Particle Size of Solids: The maximum particle size that can be handled by the pumps is 9 mm for AD 20, 12 mm for AD 32, and 14 mm for AD 50, indicating their suitability for different applications.
Suction Lift: The suction lift capability varies based on the valve material. For
stainless steel pumps with EPDM ball valves, the dry suction lift is 2 mWC for AD 20 and AD 32, and 3 mWC for AD 50. With PTFE ball valves, the values are slightly lower. The wet suction lift is consistently 9 mWC across all models.
Max. Operating Temperature: The maximum operating temperature for all models is 130°C, but it is reduced to 80°C when using a center block of PE conductive material.
