Back-Pull-Out Architecture (EN733 / ISO 2858): Enables rapid disassembly and servicing of the rotating assembly without detaching suction/discharge pipework or moving the motor.
Superior Hydraulic Efficiency (MEI >= 0.7): Optimized hydraulic volute geometry minimizes energy consumption and maintains continuous high-efficiency operation up to 550 m3/hr.
Dry Shaft Anti-Corrosion Design: The main drive shaft is completely shielded from liquid contact by a stainless steel sleeve and precision gaskets, preventing rust and mechanical wear.
Axial Thrust Neutralization: Dynamically balanced impellers utilize rear back-vanes or balancing holes to neutralize axial hydraulic thrust, drastically extending bearing operational life.
High Working Pressure & Thermal Tolerance: Built to safely handle maximum operating pressures up to 16 kg/cm2 and fluid temperatures from -10°C to +120°C across facilities in Nepal.
