SLB-C, SLB-S, SLB-N 4. Technical Data 4.1 Temperatures ¾ Ambient temperature: 0°C to +50°C If ambient temperatures are above +40 degrees C, or if the pump is located at elevations more than 1,000 meters above sea level, the motor’s output must be derated to compensate for less effective cooling, and may have to be replaced with a larger size motor. -
Page 4: Electrical Data
SLB-C, SLB-S, SLB-N 4.4 Electrical data Make sure that the supply voltages, phase and frequencies correspond to the motor specifications. 4.5 Number of starts per hour Motors up to and including 4 kW : Maximum 100 times per hour. Motors of 5.5 kW and up : Maximum 40 times per hour. For other manufacturer’s motors, check their instructions for the maximum frequency of starts. - Page 5 SLB-C, SLB-S, SLB-N Pos. Description Pipe support: Support piping system properly to avoid stresses on connections. On-off valves: Install on-off valves for easy access before the pump intake and after the pump dis- charge. Use flexible piping on both input and output sides of the pump to reduce vibration and transmission of noise.
- Page 6 SLB-C, SLB-S, SLB-N Pos. Description If it is necessary to increase the diameter of the suction pipe, place an eccentric reducer between the check valve and the flexible pipe section. Using elbows will increase the flow resistance. Wide bends will result in lesser flow resistance. The piping must have a level or positive gradient to prevent the formation of air pockets.
