Type NDX pump is applicable for pumping clean water and liquids whose physical and chemical properties are similar to water and without solid particles. This series of products can be used in factories, mines, urban water supply and drainage, HVAC, industrial softened water and farmland irrigation and drainage. It is also highly effective for pressure stabilization and water supply systems in urban fire control.
Pump performance can be adjusted by cutting the outer diameter of the impeller. The normal operating speeds are 1450RPM and 2900RPM. For high-speed operation at 3550RPM (60Hz), technical instruction for impeller diameter modification can be provided. The pump features a simple structure, reliable performance, high efficiency, and convenient maintenance.

Product & Structural Features
Energy Efficient Design
Utilizing advanced NRCE design and CFD fluid simulation software to achieve high reliability and wide efficiency zones, reaching international standards for both design and non-design conditions.
Rear Opening Structure
Maintenance is made easy as it is not necessary to disassemble the suction and discharge pipes to pull out the rotor parts.
Footing Support Pump Casing
The casing can withstand up to 2.5MPa of pressure. Flanges can be drilled according to metric or American systems for global compatibility.
Dynamic Balance Testing
100% of impellers and rotor components are tested to ensure smooth operation, lower vibration, and reduced noise levels.

Frequently Asked Questions
What types of liquids can the NDX pump handle?
It is designed for clean water and liquids with similar physical and chemical properties that do not contain solid particles.
What is the maximum operating temperature?
The standard pump is suitable for medium temperatures ranging from -10°C to 85°C. For higher temperature requirements, custom specifications can be ordered.
Is the pump easy to maintain?
Yes, the rear-opening structure allows you to remove rotor parts for maintenance without disconnecting the suction or discharge piping.
What kind of bearings and seals are used?
We use high-quality imported NSK bearings and Vulcan mechanical seals to ensure long service life and zero leakage.
Can I use this pump for fire control systems?
Absolutely. This series is commonly used for pressure stabilization and water supply in urban fire control applications.
Are different motor frequencies supported?
The standard speeds are for 50Hz (1450/2900 RPM), but we can provide technical guidance for 60Hz (3550 RPM) operation involving impeller adjustments.
