It is not possible to decrease the speed of this Eberspacher Hydronic water pump. Descreasing the speed/flow would have a detrimental effect on the operation of the Eberspacher heater. Speed and flow rates are specific to the requirements of the water heater which senses the temperature of the coolant and operates accordingly. To slow the speed/flow would cause the heater to stop and produce errors.
