Materials and Construction
The Split-Case Fire Fighting Pump combines precision engineering with durable materials for long-term performance and minimal maintenance:
Pump Casing
Constructed from high-density cast iron with a minimum tensile strength of 35,000 psi, the casing provides outstanding strength and rigidity. The bearing bracket supports are cast as part of the lower casing to maintain perfect alignment of the bearings and rotating components.
Casing Rings
Renewable bronze casing rings minimize internal recirculation between the suction and discharge chambers, improving hydraulic efficiency and reducing wear over time.
Impeller
The double-suction impeller is a single, precision-cast bronze piece that delivers vibration-free performance. Dynamic balancing ensures smooth hydraulic operation, reduced mechanical stress, and longer bearing and seal life. The impeller is keyed to the shaft using an 18-8 stainless steel key and aligned axially with threaded shaft sleeves for stability.
Stuffing Boxes and Glands
The stuffing boxes contain at least five packing rings along with lantern rings and water seal piping. Split glands made from 304 stainless steel allow easy removal and repacking. Additionally, swing-type gland bolts with 18-8 stainless steel nuts simplify maintenance.
Shaft and Shaft Sleeves
The carbon steel shaft is protected by replaceable bronze shaft sleeves, extending beyond the packing glands for maximum protection. 304 stainless steel sleeves with O-ring seals prevent leakage and ensure long-term corrosion resistance.
Bearings
The single-row, deep-groove ball bearings are grease-lubricated for smooth operation and long service life. Their average lifespan exceeds 100,000 hours under normal conditions. Optional double-row outboard thrust bearings are available for higher load requirements.
Seal Flush Connection
As standard, the upper casing includes a tapped and plugged seal flush connection, enhancing sealing performance and system efficiency.
Features and Advantages
- High Efficiency: Double-suction impeller design ensures smooth water flow with minimal vibration.
- Easy Maintenance: Split-case design allows technicians to access the internal components without disconnecting piping.
- Long Service Life: Precision-balanced components and durable materials extend operational life and reduce downtime.
- Versatile Operation: Suitable for both electric motor and diesel engine drives to fit multiple system configurations.
- Corrosion Resistance: Optional materials and bronze fittings enhance performance in saltwater and harsh environments.
- Stable Performance: Heavy-duty bearings, balanced impeller, and precise alignment deliver consistent water pressure during emergencies.
Compliance and Standards
The Split-Case Fire Fighting Pump is designed and tested in full accordance with the following standards:
- UL (Underwriters Laboratories)
- FM (Factory Mutual Research Corporation)
- NFPA 20 – Standard for the Installation of Stationary Fire Pumps for Fire Protection
Compliance with these standards guarantees reliability, safety, and compatibility with global fire protection systems.
Why Choose a Split-Case Fire Fighting Pump?
