Description: Pierburg CWA100.3 Brushless Water Pump 20mm OD - 12v The Pierburg Electrical CWA coolant pumps make a significant contribution to emission control on modern engine designs. A delivery rate that is not dependent on the speed of another drive enables demand-based cooling. This reduces the power requirements whilst also cutting down on frictional loss, fuel consumption and pollutant emissions. The noticeable difference compared to the CWA100-2 is that the CWA100-3 has improved EMC behaviour to meet more stringent requirements. The CWA100-3 was produced to be a more accessible and universal pump which features both LIN and PWM onboard interfaces (4 pin version). The CWA100-3 has been improved for high temperature applications and higher lifetime requirements. Electrical CWA coolant pumps offer top performance. They can be used for the main cooling of the combustion engine, as well as for cooling the fuel cell stacks of fuel cell drives. Pierburg has made the electrical water pump ready for series production and was the world’s first series-production supplier for a leading premium vehicle manufacturer.Compact radial auxiliary coolant pump.Speed control and extended diagnostics information via PWM or LIN bus.Efficiency close to 40% at the nominal operating point.Demand-based cooling.High flow rate at a low pressure.Homogeneous heat dissipation.Optimised for high-temperature applications and more demanding service life requirements.Improved resistance to influences that impair EMC.SpecificationMetricImperial & OtherLiquid Temp Range-40 to 125 C-40 to 257 FAmbient Temp Range-40 to 125 C-40 to 257 FHose Size 20 mm 0.787"Nominal Diff.

The chosen frequency will be automatically detected by the pump The maximum deviation to the nominal frequency must not exceed 5% PWM Input LevelSignal DescriptionMaxMinV_HiUB + 3V* (Max 28v - 60s)0.6 UBV_Low0.3 UBGround -3V* Duty Cycle vs SpeedModeDuty CycleSpeedDescription10% - 7%Emergency RunDefault 7000 rpm28% - 12%StopStop and Reset Errors313% - 93%Min - MaxControlled Operation494% - 100%Emergency RunDefault 7000 rpm The tolerance of the pump's interpretation of the PWM signal can vary +/-2% of the duty cycle. Duty Cycle The percentage duty cycle is represented by the relationship of Thigh to TPeriod. Duty cycle is PWM. Duty Cycle %=Thigh / (Tlow + Thigh).DimensionsATTENTIONThe pump can be installed in either a horizontal or vertical position. To avoid air-locks when mounted horizontally, the outlet should be turned in such a way that it is directed upwards or is placed on the upper side of the pump body.
