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.
