This document is a manual for the operation, installation, and maintenance of the 66615X-X-C 1-1/2 inch diaphragm pump. The manual includes information about pump data, materials, weight, maximum pressure, and maximum flow rate.
This manual covers the ARO 66615X-X-C diaphragm pump, describing its design, material compatibility and modular pneumatic motor/fluid sections. It explains how the pump creates suction and pressure differentials to move fluids and lists the available service kits for gas‑side and liquid‑side repairs.
The document includes safety precautions such as grounding to prevent static sparks, detailed disassembly and re‑assembly procedures for both the liquid and pneumatic motor sections, parts lists with torque specifications, and a fault‑diagnosis guide to help identify common problems like membrane rupture or excessive pressure. This manual is written in Chinese.
