THE PRODUCT

The direct circuit pumping unit guarantees the correct water flow-rate and a correct pumping head in all heating systems or in tank loading systems when the supply temperature is the same as the heat generator working temperature.

The unit is composed of supply and return sides. The return includes service valve, thermometer and check valve. The check valve can be excluded if maintenance operations must be performed.

The supply includes service valve, thermometer, pump and a valve that allows to exclude the pump if pump maintenance operations must be performed.

The unit is supplied with supply side and pump on the right. For some model, supply and return sides can be easily switched by simply opening the closure stirrup, inverting the two sides and closing the stirrup.

Other pumps are available on request.

The unit is equipped with pump Grundfos UPM3 Hybrid, ErP-Ready.

The by-pass valve ensures a correct water flow also if thermostatic valves are mounted on heating elements.

The insulating case has modern design and compact dimensions; it is in PPE material, density 45 Kg/mq and guarantees good isolation to all the elements and good thermal insulation. Installation and maintainability are easily reached.
