Using a circulator pump for a domestic water recirculation system may not be enough sometimes, and this is when the wise thing to do is to research some more and find a solution to the problem. The right attitude should be to purchase a booster pump such as the Grundfos mq3-45 model.

In contrast with a normal water pump, Grundfos mq3-45 has a compact motor that is equipped with a boosting option. The advantage of this system is that it can safely be used in domestic plumbing applications because it not only circulates the water, but also boosts its speed if necessary. This way, the potable water of some systems will have no risks of becoming contaminated because of a slow flow.
It is natural that because of this complex and useful option that the motor of Grundfos mq3-45 has, it needs to be protected somehow. This is the main reason why its manufacturers have installed a protective function and an automatic reset option. They both guard over the well-being of the unit, keeping its performance at its best and ensuring its long life.
Similar to many other water pumps, the Grundfos mq3-45 has a temperature range at which the liquid should flow in order for the device to be secure and to work properly. For this model, the range is between 0 and 35 degrees Celsius. Additionally, the maximum pressure at which it can operate is of 109psi, because of the glass fiber that forms part of the impeller and pump housing.

To conclude, this model of water pump is best for those houses with a plumbing system that will not work properly because of the slow flow of water. Due to its boosting system, this pump will not only purify the water, but it will also keep it clean and safe to drink.
