Horizontal radially split volute casing pump in back pull-out design, with radial impeller, single-entry, single-stage, to ISO 2858 / ISO 5199. Optional TRD type testing by TÜV. ATEX-compliant version available.
Application pump hpk
Pumping hot water and thermal oil in piping systems or tank systems, particularly in medium-sized and large hot-water heating systems, forced circulation boilers, district heating systems
- Q max 4,800.0 m³/h
- H max 275.0 m
Fields of Application hpk
HPK pumps in standard design are used for plants where hot water thermal oils must be transported in pipeline or tank systems, particularly in medium-sized and large heating systems, forced circulation boilers, district heating systems and similar.
HPK-E and HPK-E4 have been type-tested to TRD (German Steam Boiler Regulations) by TÜV (Technical Control Board).
Type test certificates can be offered and supplied on request.
Desing Details pump hpk
reduced axial thrust and shaft seal balancing due to back vanes.
Radially split, consisting of volute casing and discharge cover.
HPK-S with casing wear ring, HPK-E without casing wear ring.
Double volute depending on the pump size.
Axial thrust is balanced by means of back vanes
Rotor and bearings
are dimensioned so as to ensure a shaft deflection below 0.05 mm and a bearing life of more than 17500 operating hours
