Final model selection should be confirmed according to the actual duty point, system requirements and applicable fire protection standards.

Installation and Maintenance

Installation Guidance

The pump should be installed on a rigid, level foundation with adequate clearance for inspection and maintenance access. The suction and discharge piping must be independently supported to prevent load transfer to the pump flanges.

Pre-Start Inspection

Before starting the pump, confirm the following:

• Pump is securely mounted and level
• Suction and discharge piping connections are complete and leak-free
• Pump casing is properly filled and primed
• Motor wiring and connections are secure
• Rotational direction matches the arrow indicated on the pump casing
• All fasteners are properly tightened

Routine Maintenance

Regular inspection should include:

• Checking mechanical seals for leakage
• Monitoring motor bearing temperature and vibration levels
• Verifying that the pump maintains the required flow and pressure during test runs
• Inspecting all pipeline connections for signs of leakage
• Cleaning strainers and filters when necessary

Available Configurations

• Flow rates from 40 to 350 L/s
• Pressure range from 0.3 to 2.0 MPa
• Motor powers from 30 to 450 kW
• Various stage configurations for different head requirements
• Electric motor or diesel engine drive options
• Integrated control panels with automatic start and monitoring
