Page 4: Introduction
In case a diaphragm gets damaged, fluid will gush out together with air through the exhaust port. Provide protective measures in consideration of possible leakage of fluid. When you using the hose and pit etc, make sure to use a model with appropriate corrosion resistance for the fluid to be pumped. 4I DELLMECO I AODD DIAPHRAGM PUMPS... - Page 5 Ø Use only genuine Dellmeco parts when replacing component parts of this product. Torque of all tightening parts must be checked before running the pump. Designated torques are mentioned in maintenance manual.
