Product Description

 

Horizontal Double Suction Split Case Centrifugal Pump Water Pump for Water Circulation 

Product Description

Brief introduction :

Horizontal split case pump is a type of centrifugal pump that has two single suction impellers or a double suction supported between bearings. The pump casing is split axially with opposing suction and discharge flanges. This allows for easy maintenance on the pump.

Split case pump are typically used to carry low-viscosity liquids such as clear water and unsaturated wastewater from industrial processes at average heads. it can be applied for higher flow rate conditions that are not suitable for end suction pumps, such as fire pumps, portable water distribution, plant make-up water, pipelines, cooling water, and other industrial process flows with fairly thin fluids.

Features   

1. Large flow capacity, high efficiency.
2. Easy operation and maintenance.
3. Long operational life- The life of the pump casing should extend to at least 30 years, with a pressure threshold of up to 10MPa.
4. The location of the inlet and outlet flange of the split case pump can be custom placed upon request.
5. The shaft, impeller, shaft sleeve, and sealing ring can be composed of a selection of different materials according to the working conditions, including cast iron, cast steel, and stainless steel (SS304, SS410, etc.).
6. Seal method: machinery seal and packing seal varieties available.

Performance Parameters:

Pump outlet diameter Dn	100~900mm
Capacity Q	72~20000m3/h
Head H	7~186m

Application

 Split case centrifugal pumps are versatile and commonly used across various industries for high-flow, medium-pressure applications, including water supply, fire protection, and industrial processes. Their key features are a horizontally split casing for easy access to internal parts, a double-suction impeller for high efficiency and balanced hydraulic forces, and robust construction for demanding environments. 

Applications:
Water Supply and Treatment:
Municipal water plants, irrigation systems, and desalination plants rely on split case pumps for efficient water distribution and treatment. 
Fire Protection:
They serve as reliable fire pumps, providing high-pressure water supply for fire suppression systems. 
HVAC Systems:
Split case pumps circulate chilled and hot water in heating, ventilation, and air conditioning systems
Industrial Processes:
Chemical processing, power generation, oil and gas, mining, and paper mills utilize these pumps for various fluid handling needs
Other Applications:
They are also found in cooling towers, condensate return systems, and dewatering operations

Advantages:
High Efficiency: Double-suction impellers and balanced hydraulic design minimize energy consumption. 
Easy Maintenance: The split casing design allows for quick access to internal components for inspection and maintenance. 
Durability: Rugged construction enables reliable performance in demanding conditions. 
Balanced Design: Reduces axial thrust and extends the life of bearings and seals.
