For help selecting the exact model based on the required flow rate and head, contact us with your Q and H requirements.
Both have a DN 65 discharge and identical hydraulics. The NKM-G 65 (1 450 rpm) offers quieter operation and a head of up to 34 m – ideal for HVAC and circulation. The NKP-G 65 (2 900 rpm) delivers a head of up to 69 m – for pressure applications and greater delivery heads.
DN 65 is a versatile size for medium-sized applications. With 10 models in 5 casing sizes (125–315), the NKM-G 65 covers operating points ranging from small circulation systems to industrial piping – simply choose the right combination of flow rate and head.
Tell us the required flow rate (Q) and head (H), and we will recommend the most efficient model for your operating point.
NKM-G pumps come with a 24-month warranty.
