GENERAL INFORMATION

1.1

USES

Circulating pumps NMT SMART 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 three versions of NMT SMART pumps:
NMT(D) SMART is the most basic version without any input/output electrical signal possibility.
•
• NMT(D) SMART S comes with SSR modul which has a digital input for pump start and a relay for reporting
errors.
NMT(D) SMART C comes with NMTC module which enables remote control and monitoring using
•
Ethernet, Modbus, analog inputs and outputs, and relay control. (Detailed description available in
communication
pumps.com/documentation/«, or with scanning QR code on the cover page.)
Changing/adding SSR or NMTC module to any NMT SMART, gives the pump all the functionality of the module.
NMTD SMART pump is assembly of two pumping agregats in one hydraulic housing. The main purpose of the
twin pump is uninterrupted operation, if one of the pumps fails.
