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
Technical data
- 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
Impeller:
reduced axial thrust and shaft seal balancing due to back vanes.
Casing
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.
Balancing
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
