Horizontal End Suction Fire Pump delivers consistent performance, outstanding reliability, and long-lasting durability. Its precision-cast and dynamically balanced impeller minimizes vibration and maximizes bearing life, ensuring smooth and efficient operation. Because the pump uses a back-pull-out design, technicians can easily remove the bearing assembly, impeller, and casing cover without disconnecting the volute casing from the piping.
This clever design reduces downtime, simplifies maintenance, and keeps the system running efficiently for years. Furthermore, the pump’s robust construction ensures dependable performance even in demanding fire protection systems.
Flexible Power Options
The Horizontal End Suction Fire Pump operates with either an electric motor (50Hz / 60Hz) or a diesel engine, allowing flexibility for different installation needs. In addition, users can integrate a complete set of accessories such as controllers, jockey pumps, and relief valves. These options help ensure NFPA 20 compliance and improve overall system reliability.
The heavy-duty fabricated steel base holds both the pump and the driver. A flexible coupling connects them, which enhances power transfer, reduces vibration, and increases operational stability. Therefore, the pump delivers smooth and efficient performance under all working conditions.
Reliable and Consistent Water Delivery
When the water source is above ground, the End Suction Fire Pump provides positive suction pressure throughout operation. As a result, it maintains consistent and reliable water delivery, which is essential for effective fire suppression. Additionally, the horizontal design supports high performance with minimal maintenance.
Because of its wide range of materials, including corrosion-resistant options, this pump performs well in both standard and harsh environments. Consequently, it offers flexibility for a wide variety of applications.

Construction Details
Pump Casing
The heavy-duty volute casing features integrally cast supports and centerline discharge for optimal balance. O-ring seals between the casing and the cover ensure zero leakage. This sturdy design improves safety and reduces maintenance time.
Casing Wear Ring
The integral renewable wear rings minimize end thrust and extend the lifespan of the pump. As a result, performance remains stable over years of continuous use.
Impeller
Each enclosed impeller is dynamically balanced before assembly. Engineers design the impellers with back rings to reduce axial thrust. Since they are keyed and locked to an oversized shaft, the system absorbs heavy loads easily and operates smoothly.
Bearing Housing
The cast bearing housing supports the rotor assembly and accommodates grease-lubricated steel bearings. Both inboard and outboard bearings include protective seals that keep contaminants out and extend bearing life.
Lantern Ring
A corrosion-resistant perforated lantern ring allows cooling water to flow evenly around the shaft, ensuring proper lubrication and temperature control.
Gland Packing
Graphite packing rings provide tight sealing while allowing smooth, friction-free rotation of the shaft. This combination minimizes wear and ensures long-term performance.
Casing Cover
The casing cover includes a stuffing box built for maximum working pressure. It holds five packing rings along with a lantern ring to guarantee strong sealing and cooling.
Shaft Sleeve
Renewable shaft sleeves, made from centrifugally cast material, protect the shaft from corrosion and wear. Each sleeve locks securely in place to prevent movement during operation.
Bearing
Grease-lubricated steel bearings handle heavy loads efficiently, resulting in a long operational life and stable performance.
Shaft
The high-strength alloy steel shaft is precisely machined and polished to transmit power smoothly. Its robust structure reduces deflection and supports full driver horsepower.
Applications
The Horizontal End Suction Fire Pump serves multiple applications, including:
- Industrial and commercial fire protection systems
- High-rise building sprinkler networks
- Power plants and refineries
- Municipal water and firefighting systems
- Marine and offshore installations
Because of its efficiency, durability, and simple maintenance, this pump remains a top choice for engineers and safety professionals.
