Split Case

SFFECO Horizontal Split Case Fire Pumps are high-capacity centrifugal pumps designed to efficiently deliver large volumes of water for fire protection systems. Due to their reliable performance and robust construction, they are widely used in a variety of fire protection applications.

The horizontal split case pump features a double-suction impeller with a symmetrical water intake design. Water enters the center of the impeller from both sides, where it is accelerated by the rotating impeller blades and then directed through the volute casing to the discharge outlet. This balanced double-suction design significantly reduces axial thrust, improving pump stability, operational efficiency, and overall reliability.

Manufactured with durable materials and precision engineering, SFFECO Horizontal Split Case Fire Pumps comply with international and national fire protection standards. Their efficient hydraulic design ensures dependable performance, long service life, and consistent water delivery during both routine operation and emergency fire situations, making them an essential component of modern fire protection systems.

Key components

Pump casing:

The pump casing is typically of the split (center-opening) type to facilitate inspection and maintenance. It is usually made of cast iron, ductile iron, or other high-strength materials, allowing it to withstand high-pressure operation.

Impeller:

The impeller features a double-suction design, drawing water from both sides to reduce axial load. It is typically made of bronze, stainless steel, or other corrosion-resistant materials to ensure long service life and high efficiency.

Pump shaft:

The pump shaft connects the impeller to the driving motor and transmits rotational power. It is typically made of high-strength stainless steel, offering excellent corrosion resistance.

Bearing:

The bearing supports and stabilizes the pump shaft, reducing friction, and is typically a rolling or sliding type. Regular lubrication and maintenance are required to ensure stable and reliable pump operation.

Sealing:

A mechanical seal or packing seal is used to prevent liquid leakage. Wear-resistant and corrosion-resistant materials are typically selected to ensure durability.

Performance Characteristics

High Efficiency:

The double-suction impeller ensures stable water flow and maximizes hydraulic efficiency, providing high flow and lift while keeping energy consumption low.

Reliable Operation:

The center-opening design facilitates maintenance and inspection, minimizing downtime. The symmetrical impeller reduces axial thrust, enhancing durability and extending the pump’s service life.

Easy Maintenance:

The center-opening casing allows access to internal components without removing piping. Its compact layout and easily replaceable parts make routine servicing simple and efficient.

Installation and application

Installation:

During installation, careful attention should be given to the horizontal alignment of the pump to ensure a stable foundation and minimize vibration and noise. The suction and discharge piping must also be properly configured to prevent cavitation.

Application:

It is widely used in high-rise buildings, large commercial centers, industrial facilities, and municipal water supply systems. It is also suitable for building fire sprinkler and hydrant systems that require high flow and high lift.
