For precise model selection based on the required flow rate and head, contact us with your Q and H requirements.
NKP-G 50 (2 900 rpm) delivers a head of up to 93 m, making it ideal for pressure applications. NKM-G 50 (1 450 rpm) delivers a head of up to 24 m, but runs more quietly and has lower wear – making it suitable for circulation circuits.
Tell us the required flow rate (Q) and head (H) – we’ll recommend the most efficient model for your required operating point.
We provide a 24-month warranty on NKP-G pumps.
We can create the perfect seal for your needs, including non-standard sizes.
