GENERAL INFORMATION
1.1
USES
The NMT (new motor technology) circulating pumps are used for the transfer of liquid medium within systems for
hot-water heating, air-conditioning and ventilation. They are designed as single or twin variable-speed pumping
aggregates where the speed is regulated by electronic device. The pump constantly measures pressure and flow and
adjusts the speed according to the set pump mode.
There are two versions of NMT (D) MAX. NMT(D) MAX has an input digital input for pump start and a relay for
reporting errors. NMT(D) MAX C comes with NMTC module which enables remote control and monitoring using
Ethernet, Modbus, analog inputs and outputs, and relay control.
NMTC module can be added later to the pump, giving it communication options of NMT(D) MAX C. NMTC module
has separate instrucstions regarding, which is located on our website: " https://imp-pumps.com/documentation/.

The main purpose of the twin pump is uninterrupted operation if one of the pumps fails. Common hydraulic housing
is equipped with a change-over flap and two pump heads, separately connected to the electrical grid.
