Welch 2163 6.1 Cfm Full Chemical-Resistant 8-Head Diaphragm Pump

HANDLING
Place the pump on a stable, level surface with adequate ventilation and clearance for proper airflow. Secure all vacuum connections before operation and use compatible tubing, fittings, and components when handling chemical or solvent vapors. Avoid restricting the pump inlet or exhaust, and inspect connections regularly for leaks, wear, or contamination.

STORAGE
When not in use, keep the pump in a clean, dry, temperature-controlled environment away from excessive moisture, dust, corrosive materials, and direct heat. Disconnect power and protect the inlet and outlet connections from contamination. Before extended storage, follow Welch’s recommended cleaning and shutdown procedures, particularly after exposure to aggressive or condensable vapors.

Operate the pump on a stable, well-ventilated surface and use only with vapors and materials compatible with the pump’s wetted components. Ensure inlet and exhaust connections are properly secured and route exhaust gases to an appropriate ventilation or capture system when processing hazardous or corrosive vapors. Disconnect electrical power and fully vent the system before cleaning, inspection, or maintenance. Always follow Welch operating instructions, chemical SDS requirements, and applicable facility safety procedures.
