Assembly: SKF/NSK bearings, options for double-mechanical seals, and dynamic balancing for low vibration (<2.8mm/s ISO).
Factory Performance Test: Each horizontal split case pump is tested on fully automated hydraulic test beds with digital data logging.

Standards & Quality Control

Testing Standards: Factory Acceptance Testing (FAT) to ISO 5199, hydraulic efficiency per API 610, and vibration checks as per ISO 10816.
Corrosion Resistance: All wetted components can be supplied in 316SS or duplex for aggressive applications.
Coating: Epoxy/polyurethane paints resist chemical and weather attacks for 15+ years.

Application Scenarios for Horizontal Split Case Pumps: Real-World Performance & Cost Savings

Typical Industries and Use Cases

Municipal Water Supply/Distribution: Large flow, low-NPSH service, high duty cycle ensures low OPEX over 20yrs+ lifecycle.
Industrial Cooling Water: Continuous operation in steel, chemical, and power plants; double suction impeller for balanced axial thrust and minimal wear.
Seawater Desalination & Intake: Special duplex/monel options solve corrosion and cavitation in marine environments.

Expert FAQ: Technical Terms & Best Practices

1. What is a horizontal split case pump?

A horizontal split case pump is a centrifugal pump whose casing is divided along the horizontal axis. This allows for easy inspection, maintenance, and removal of the rotor without disturbing pipework or motor alignment—a major advantage in large-flow, mission-critical installations.

2. What are typical materials used in double suction horizontal split case pumps?

Standard materials include cast iron, ductile iron, 316L stainless steel, duplex stainless steel, bronze, and for aggressive media, super-austenitic or nickel-aluminum bronze.

3. What are the key technical parameters to specify?

Capacity (Q), Head (H), Efficiency (η), NPSHr (Net Positive Suction Head required), Seal type (mechanical/gland/cartridge), Bearing brand, Material construction, and Standards compliance (e.g., ISO 5199, API 610).

4. How are horizontal split case pumps installed and aligned?

Installation should follow ANSI/ASME B73.1 or manufacturer guidelines. This includes baseplate grouting, proper shaft alignment (laser alignment tolerance <0.05mm), and hydrodynamic compensation for thermal expansion in high-temperature use.

5. What’s the typical service life and warranty?

High-quality horizontal split case pumps offer a mechanical service life of 20+ years, owing to low journal pressure, balanced axial forces, and ease of impeller/bearing replacement. The SSH series comes standard with a 24-month warranty and extended spares support.

6. What certifications are important for critical sectors?

Look for ISO 5199, API 610, ISO 9906 hydraulic testing, CE (for EU market), UL/FM (firefighting), and ATEX for hazardous use. All SSH pumps are supplied with mill certificates and test documentation.

7. Is after-sales support & remote monitoring available?

Yes. SSH and leading suppliers provide training, remote condition monitoring (vibration/temperature), same-day technical support, and annual health assessments for critical plant installations.
