Product overview
These pumps are non-self-priming, single-stage centrifugal pumps with axial inlet, radial outlet and horizontal shaft.
The inlet flange and outlet flange of NKG are PN 16.
Size and rated performance meet ISO 2858(16 bar) standard.
NKG pump is a long shaft structure, equipped with a fully enclosed fan-cooled standard motor. Its main dimensions meet IEC and DIN standards, and its installation method is B3(IM1001).
The size of mechanical seal meets the standard of EN 12756.
The flow provided by NKG pumps ranges from 2 to 1200m3/h, the lift ranges from 2 to 160m, and the power range of motors ranges from 0.25 to 355kW. NK has a flow range of 200 to 2000m3/h and a lift of 12 to 100m.
Pumps with power requirements ranging from 1.1 kW to 22kW can choose motors with built-in frequency converters. We call these pumps NKGE.
All pumps are dynamically balanced according to ISO 1940 class 6.3. The impeller is hydraulically balanced.
The product range of NKG includes two product ranges: "standard range" and "high efficiency range". EFF1 motor is used for high-efficiency products; The standard range of products adopts EFF 2 motor.
The pump is designed with a pull-back structure, and the motor, coupling, bearing seat and impeller can be disassembled without disassembling the pump shell or pipeline. Even for the largest pump, a single person can use a lifting device to maintain it.
