2 Safety 2 Safety All the information contained in this section refers to hazardous situations. DANGER 2.1 Key to safety symbols/markings Table 2: Definition of safety symbols/markings Symbol Description DANGER DANGER This signal word indicates a high-risk hazard which, if not avoided, will result in death or serious injury.
2 Safety ▪ Observe the maximum flow rates indicated in the data sheet or product literature (to prevent overheating, mechanical seal damage, cavitation damage, bearing damage, etc). ▪ Do not throttle the flow rate on the suction side of the pump (to prevent cavitation damage).
2 Safety ▪ If shutting down the pump does not increase potential risk, fit an emergency- stop control device in the immediate vicinity of the pump (set) during pump set installation. 2.8 Safety information for maintenance, inspection and installation ▪ Modifications or alterations of the pump are only permitted with the manufacturer's prior consent.
On transfer of goods, check each packaging unit for damage. In the event of in-transit damage, assess the exact damage, document it and notify KSB or the supplying dealer (as applicable) and the insurer about the damage in writing immediately.
