 Product Description

CME Plus pumps are built on the basis of CME pumps. In addition to the features of a standard CME, the CME plus includes a pressure sensor, expansion tank, and discharge piping making it a complete package ready for constant pressure applications.

The CME Plus provides constant water pressure for a variety of domestic applications. This means that the end-user is no longer bothered by fluctuations in water pressure due to a rise or fall in demand, or from pump starts and stops. CME Plus keeps the pressure within the home up regardless of usage. The constant pressure feature provides the benefit of increased comfort.

In addition the CME Plus makes it possible to personalize the water pressure. By the touch of a button the pressure level is increased or decreased as desired.

The CME Plus incorporates a stop function ensuring that the pump automatically stops if the water demand drops to a very low level or disappears altogether. The method gives good total operating economy irrespective of the water demand, and the pump is not subjected to overheating and the subsequent risk of damage to the shaft seal.
