Seal HR Features (HBHR)

Single seal
Balanced
Independent of direction of rotation
Multiple springs stationary
Seat rotating
Seat arranged directly behind the impeller
Spring protection sleeve
Variant with cylindrical spring and acc. EN 12756 (HRZ1) available
Variant as cartridge with/without guide sleeve for application with/without quench (HR2, HR3)
Dual seal as cartridge unit (HRKS-D) available

Seal HR Material

Seal face: Silicon carbide (Q1, Q2)
Seat: Silicon carbide (Q1, Q2)

Seal HR Advantages (HBHR)

Especially for application in solids containing media without external flush or internal product circulation. Solids content 40 % (single seal) and 60 % (double seal)
Operation under vacuum without seat locking possible
Pumping screw for increased circulation available
Springs are protected from product and leakage

Seal HR Recommended applications

Process industry
Oil and gas industry
Refining technology
Chemical industry
Power plant technology
Pulp and paper industry
Water and waste water technology
Mining industry
Sugar industry
Cement industry
Contaminated, abrasive and solids containing media
Sewage water pumps
Dredger pumps
Oil sand extraction
Suspension pumps of flue-gas desulphurization plants (FGD)
