Modular Segmental Ring Construction: Individual stage casings are securely clamped using high-tensile tie-bolts, allowing flexible head configuration to match precise operational demands.
Automatic Hydraulic Axial Thrust Balancing: Incorporates a precision balancing drum/disc mechanism that automatically counteracts heavy multi-stage axial loads, protecting bearings from premature wear.
Massive 500-Meter Head & 64 Bar Pressure: Engineered to deliver high-pressure fluid displacement scaling up to 500 meters total head and flow rates up to 280 m3/hr.
Specialized High-Temperature Boiler Trims (RKBK): Available with cooling jackets and water-cooled stuffing boxes designed for thermal power plants, condensate return, and boiler feed cycles up to +110°C and above.
Rigid Short-Span Shaft & Wear Rings: Features a high-tensile stainless steel or carbon steel drive shaft shielded by renewable sleeves and interstage bushes to ensure low vibration across installations in Nepal.
