NKV 1/3/6/10/15/20

DAB's NKV S pumps are AISI 304 stainless steel multi-impeller vertical centrifugal pumps with coupling; designed for pressurization, conditioning and heating in civil environments, they can also be used in agriculture and in watering systems. The pumps can be used for the recirculation of water in heating and air conditioning systems. Versatility, thanks to the center distance between the 2 in-line ports, designed to maximize interchangeability. Starting from 5.5 kW models, the mechanical seal can be removed without removing the motor. Mechanical seals for aggressive liquids and different connections (round, oval, Victaulic, clamp flanges). WRAS and ACS certified for use with drinking water. IE3 electric motors with ambient temperature up to +50°C.

Specification

APPLICATIONS
NKV are AISI 304 stainless steel multi-impeller vertical centrifugal pumps with coupling; designed for pressurization, conditioning and heating in civil and commercial environments, they can also be used in agriculture and in watering systems. The pumps can be used for the recirculation of water in heating and air conditioning systems.
CONSTRUCTION FEATURES OF THE PUMP - NKV 1-3-6-10-15-20 S
The use of advanced stainless steel processing technologies for the main hydraulic components helps to achieve very high performance levels. The pumps are also 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 to 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
Standard mechanical seal E1 (= Graphite/ Silicon Carbide/AISI 316/EPDM) and on request among the various custom seals there are also with FKM/Viton. The seal can be dismantled without removing the motor from 5.5 kW. Rigid coupling. Motor frame B14 up to 4 kW motor size and B5 from 5,5 kW motor size.
