Customer Benefits

Energy-Efficient Operation

The hydraulically optimised impeller design and efficient motor selection reduce power consumption during continuous operation, lowering utility costs over the pump service life.

Space-Saving Vertical Design

The vertical arrangement requires significantly less floor space than equivalent horizontal multistage alternatives, making the CDLF Series ideal for confined pump room layouts.

Hygienic Water Transfer

Stainless steel wetted components ensure clean, contamination-free water transfer suitable for domestic water supply and water treatment applications requiring hygienic conditions.

Extended Service Life

The rational structural design and corrosion-resistant stainless steel materials reduce component wear and extend maintenance intervals, lowering total cost of ownership.

Consistent Performance

The multistage impeller arrangement provides stable head and flow output across a wide operating range, accommodating system demand variations without performance degradation.

Wide Operating Range

With flow rates from 2 to 200 m³/h and heads from 5 to 280 m, the CDLF Series covers a broad spectrum of pressure boosting and circulation requirements.

Installation and Maintenance

Installation Guidance

The pump should be installed on a level, stable foundation with adequate clearance for inspection and maintenance access. The inlet and outlet pipelines must be properly supported so that no external load is transferred to the pump connections.

Pre-Start Inspection

Before starting the pump, confirm the following:

• Pump is securely mounted and level
• Pipeline connections are complete and properly aligned
• Inlet and outlet passages are unobstructed
• 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 from 2 to 200 m³/h
• Heads from 5 to 280 m
• Motor powers from 0.75 to 110 kW
• Rotational speed: 2900 r/min
• Outlet diameters from DN25 to DN150
• Different stage configurations for varying pressure requirements
