Fields of Application pump hph
HPH pumps are suitable for handling hot water in high-pressure hot water generating plants.
They are used as feed and circulating pumps.
HPH has 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 hph
Impeller
- closed radial impeller
- with multiply curved
- vanes, hydraulically
- balanced
Shaft
- not in contact with the fluid
- handled (dry shaft, therefore no special materials required)
Flanges
up to PN 160 to DIN, other flange designs possible
Casing
Radially split volute casing with replaceable casing wear ring and integrally cast centreline pump feet.
The pressure-retaining pump chamber is closed off towards the motor side by means of a bearing bracket lantern with integrated cooling chamber.
