Type NHX is designed for use in medium and large hot water systems.

It is a single-stage volute casing pump, with an axial suction flange and axial centerline mounted discharge flange pointing vertically upwards. The design of the DICKOW hot water circulation pump takes into account many years of experience in the hot water sector and allows for high operational reliability.

The DICKOW patented cooling and degassing system ensures moderate temperatures in the sleeve bearing area and guarantees a stable liquid film in the mechanical seal gap.

The pump is self-venting and does not require any external or water cooling. Personnel-intensive intervention from the outside is not required. High antifriction bearing temperatures are prevented even under extreme load conditions. Lowest life cycle costs by efficient hydraulics and low maintenance requirements
