If the pump is to be operated at a higher temperature, if there is no data sheet or if the pump is part of a pool of pumps, contact KSB for the maximum permissible operating temperature. 2.10.3 Monitoring equipment The pump (set) must only be operated within the limits specified in the data sheet and on the name plate.
Page 12
2 Safety Contact KSB for further information on monitoring equipment. 2.10.4 Operating limits The minimum flows indicated in (⇨ Section 6.2.3.1 Page 35) refer to water and water- like fluids. Longer operating periods with these fluids and at the flow rates indicated will not cause an additional increase in the temperatures at the pump surface.
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.
