Grundfos NK 100-200/182 A2F2AE-SBQQE

Grundfos NK/NKG standard and block pumps are versatile pumps, suitable for a wide range of applications that demand reliable and efficient supply. The NK/NKG series consist of non-self-priming, single-stage centrifugal volute pumps with axial suction port, radial discharge port and a horizontal shaft. Thanks to their robustness and reliability, the Grundfos NK and NKG pumps are ideal for use in the water supply, industrial pressure boosting, industrial liquid transport, the indoor climate (heating, ventilation and air conditioning), irrigation and process industries. The pumps are easy to maintain as the motor, coupling, bearing housing and impeller can be removed without removing the pump housing or pipework.
