Product Applications

NKVE are AISI 304 Stainless Steel multi-impeller vertical centrifugal pumps with coupling; with MCE-P variable frequency drive installed as standard. This product is manufactured by Dab. The pumps are engineered for pressurization in civil and commercial environments, they can also be applied in agriculture and in watering systems. Possibility of remote control with D.Connect (D.Connect Box supplied separately).

Construction Includes Of The Pump

The use of advanced Stainless Steel processing technologies for the main hydraulic components helps to achieve very high performance levels.
The pumps are extremely versatile, thanks to the center distance of the in-line ports, designed to maximize interchangeability.
The parts in contact with the liquid are made of AISI 304 Stainless Steel for NKV S models, or AISI 316 Stainless Steel for NKV X models (only available in special order).
Round flanges as standard (oval, loose, virtual, clamp available on request).
The mechanical seal is made of standard E1 = Graphite/Silicon Carbide/AISI 316/EPDM = BQGE.
FKM/Viton available on request.
Starting from 5,5 KW models, the seal can be removed without removing the motor.
Rigid coupling.

Construction Features Of The Motor

Air-cooled asynchronous motor.
Standard two-pole motor, IE3 50 Hz 0,75 KW or IE2, IE3 60 Hz 0,75 KW.
Motor frame B14 up to 4 KW motor size, motor frame B5 from 5,5 KW motor size.

Construction Features Of The Electronics

The use of the MCE-P variable frequency drive has many advantages: better comfort thanks to the constant pressure at the variation of demand (pressure sensor installed as standard), increased efficiency, energy savings, protection from hammering effects, simpler configuration thanks to the display.
It makes it possible to set a setpoint in case of units with several pumps (each with MCE-P variable frequency drive), or to start a different pump at each restart or at set intervals.
It must be installed on the motor fan cover, also to take advantage of its cooling capabilities.

The DAB NKVE 15/06 S 055 T MCE55/P-IE3 Multi-Stage Centrifugal Pump - 415v - Three Phase - 417 Ltr/min. is a Centrifugal Pump item. Voltage for this item is 400V. It has an actual flow rate of 417 Ltr/min. The maximum head for this pump is 88m. This is a Surface Mounted pump which can be suitable when the pump can sit in a dry, accessible location and draw liquid in via a suction pipe or hose.

Wet rotor electronic circulator engineered for the circulation of water in conditioning and heating systems in commercial building service. This product is manufactured by Dab. The single version includes insulation shells.
The Evoplus D versions are supplied as standard with an automatic non-return suction valve incorporated in the delivery port to avoid water recirculating through the unit when it is not running and a blank flange for servicing either of the two motors. Possibility of remote control with the DConnect service (DConnect Box supplied separately).
