High Flow, Low Noise, Single Stage, Double Suction Centrifugal Pump
Double Suction Centrifugal Pump Product Overview
This high-flow, low-noise, high-efficiency, energy-saving single-stage, double-suction centrifugal pump is a modern water pump that combines high performance, low energy consumption, and stable operation. Utilizing advanced ternary flow theory and a double-suction impeller design, combined with precision casting technology, it achieves its core advantages of high flow, high head, low vibration, and low noise. It is widely used in waterworks, industrial water supply, urban drainage, fire protection systems, air conditioning circulation, petrochemicals, and other fields, making it an ideal choice for modern fluid conveying systems.
Double Suction Centrifugal Pump Core Advantages
High-Flow, High-Efficiency Pumping
The flow range covers 75 to 33,600 m³/h, meeting the diverse needs of small and medium-sized water supply systems to large industrial circulation systems.
The symmetrical layout of the double-suction impeller reduces axial forces, improves cavitation resistance, and significantly enhances pump efficiency.
Low-Noise, Stable Operation
The optimized impeller hydraulic model and rigid rotor design ensure smooth operation with a noise level below 75 dB(A), making it suitable for noise-sensitive environments (such as residential areas, hospitals, and office buildings). Research-and-developed bearings ensure low friction, long life, and quieter operation.
High efficiency and energy saving, reducing operating costs.
Compliant with international ISO 9908/5199 standards, this pump boasts 15%-30% higher energy efficiency than traditional pumps.
A low-pulsation impeller and self-balancing structure reduce energy loss and are compatible with variable frequency drive systems, resulting in significant energy savings.
Easy maintenance and long service life.
The horizontal split-case pump body allows for quick replacement of core components (such as the impeller and seals) by simply opening the pump cover without removing the inlet and outlet piping or motor for maintenance.
Key components (sleeves and seals) are made of highly wear-resistant materials, extending service life and reducing maintenance frequency.
Suitable for various scenarios.
It can pump clean water, industrial circulating water, and lightly corrosive liquids, with a medium temperature range of -15°C to 105°C (customization available upon request).
It supports horizontal or vertical installation and is compatible with both mechanical and stuffing box seals to meet diverse operating requirements.
Double Suction Centrifugal Pump Typical Application Scenarios:
Municipal and Industrial Water Supply
Waterworks boosting and water supply, secondary pressurization of urban pipelines, industrial boiler feed water, and cooling water circulation systems.
Firefighting and Emergency Systems
High-rise building fire pumps, emergency drainage in chemical parks, and flood control and drainage projects.
Energy and Environmental Protection
Power plant circulating water systems, sewage treatment plants, and reverse osmosis pretreatment for seawater desalination.
HVAC and Building Support
Air conditioning chilled water circulation, heating networks, and heat and cold source distribution in commercial complexes.
