(The hydraulic section is identical to that of the NKP-G 40 / NKM-G 40. For the exact casing and motor selection, please contact us.)
The hydraulic section is identical. The KDN 40 (1 450 rpm), mounted on a baseplate, allows you to choose the motor, simplifies servicing and offers higher power. The NKP-G 40 / NKM-G 40 models in en bloc design are more compact. KDN also uses an AISI 420 shaft and Viton seals.
KDN pumps come with a 24-month warranty.
