Back-Pull-Out & Spacer Coupling Design: Allows fast inspection and servicing of the rotating assembly without unbolting suction/delivery piping connections or removing the drive motor.
Corrosion-Proof Dry Shaft Architecture: The high-tensile drive shaft is fully protected from liquid contact by an interlocking stainless steel shaft sleeve, preventing rust and mechanical erosion.
Dynamically Balanced Enclosed Impellers: Precision-balanced impellers minimize mechanical vibration, suppress operational noise, and reduce bearing wear over long continuous runs.
Replaceable Casing Wear Rings: Fitted with renewable wear rings in cast iron or bronze that prevent permanent casing erosion and preserve long-term volumetric pumping efficiency.
High Working Pressure & Thermal Tolerance: Built to withstand maximum operating pressures up to 16 kg/cm2 and fluid temperatures from -10°C to +90°C across industrial sites in Nepal.
