Selection Guidance

To select the appropriate horizontal end-suction centrifugal pump, please provide the following information:

• Required flow rate (m³/h or L/s)
• Required head (m)
• Liquid type and temperature
• Pipeline diameter and connection type
• Available voltage and frequency
• Installation space constraints
• Operating conditions and duty cycle

Flow rate, head, motor power, pump quantity and control method can be determined according to specific customer requirements and project operating conditions.

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 is correct and terminals 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 head
• Cleaning strainers and filters when necessary
• Inspecting all pipeline connections for signs of wear or leakage

Available Configurations

• Flow rates customised per project requirements
• Head customised per project requirements
• Motor powers customised per project requirements
• Pump quantity and control method determined per project
• Various impeller diameters for different duty points
• Integrated control panels with automatic start and monitoring
