TWIN PUMP OPERATION

Twin pumps have double hydraulic housing with integrated check valve, which automaticly turns based on flow,
and two separated motors.
Basic versions NMTD SMART and versions NMTD SMART S do not have a control logic that ensures the continuous
operation of at least one pump - the control logic must be carried out by the customer / user himself. It is
recommended that the control logic exchanges pumps for operation with time interval of ≤ 24 h.
NMT(D) SMART C pumps can operate in several different modes, switching betweend the pumps is done by the
communications module:
-
Alternating operation [default setting] – One pump is operating while the other one is on standby.
Pumps switch their role every 24 hours or when an error occurs on one pump.
-
Backup operation – One pump operates constantly and the other one is on standby. If an error occurs
on the operating pump the one on standby will automaticly start working. This mode can be set up by
turning off the pump that we wish to be on standby. That is done by holding the
-
Parallel operation – Both pumps work at the same time with the same settings of constant pressure.
This mode is used when greater flow than one single pump can output is needed. When the first pump
hits its flow limit the second one turns on and compliments the first to reach desired flow. This mode is
activated when we set both pumps to constant pressure mode. Night mode is not recommended in this
mode of operation.
