Product Overview

The CDK Series Pump Control Cabinet is a standard electrical control panel designed for pump motor starting, running and protection. The cabinet provides direct-on-line (DOL) or star-delta starting options with comprehensive motor protection including overload, overcurrent, phase loss and short-circuit protection. It is suitable for applications where variable frequency control is not required and simple, reliable pump operation is the primary objective.

This control cabinet is widely used in building water supply systems, industrial water circulation and agricultural irrigation applications. Depending on regional terminology, it may also be referred to as a Pump Control Panel, Motor Control Cabinet, CDKControl Cabinet or Pump Control Cabinet.

Selection Guidance

To select the appropriate CDK Series control cabinet, please provide the following information:

• Number of pumps to control
• Motor power rating for each pump (kW)
• Starting method preference (DOL or Star-Delta)
• Control mode requirements (manual, automatic)
• Available voltage and frequency
• Installation environment (indoor, outdoor, pump room)

Final model selection should be confirmed according to the actual system requirements and project conditions.

Installation and Maintenance

Installation Guidance

The control cabinet should be installed in a clean, dry, well-ventilated environment with adequate clearance for heat dissipation and maintenance access. The cabinet must be securely mounted on a level surface or wall. All power and control cable connections must be made by qualified electrical personnel.

Pre-Start Inspection

Before commissioning, confirm the following:

• All power and control cable connections are secure and correctly wired
• Earth connection is properly established
• Cabinet enclosure is properly sealed and door is closed
• Overload relay settings are correctly configured for the motor rating
• Control mode selector is set to the required position

Routine Maintenance

Regular inspection should include:

• Checking terminal connections for signs of loosening or overheating
• Inspecting contactor contacts for wear and pitting
• Verifying overload relay settings and trip functionality
• Testing protective functions at regular intervals
• Cleaning cabinet interior and exterior surfaces

Available Configurations

• Single pump to multi-pump configurations
• Motor power ratings customised per project requirements
• Direct-on-line (DOL) or Star-Delta starting methods
• Manual / Automatic control modes
• LED indicator lights and meters for status monitoring
• IP54 enclosure rating (customisable)

FAQs

What is a CDK Series pump control cabinet?

It is a standard electrical control panel designed for pump motor starting, running and protection, providing direct-on-line or star-delta starting with comprehensive motor protection.

What is the difference between DOL and Star-Delta starting?

Direct-on-line (DOL) starting applies full voltage directly to the motor, suitable for smaller motors. Star-Delta starting reduces the starting current by initially connecting the motor in star configuration, then switching to delta, suitable for larger motors.

What protection functions are included?

Overload, overcurrent, phase loss and short-circuit protection are standard.

Can the cabinet control multiple pumps?

Yes. The CDK Series supports single pump to multi-pump configurations.

Where can the CDK Series be used?

It is widely used in building water supply systems, industrial water circulation, agricultural irrigation, fire protection pump control and general industrial motor control applications.

Why choose a standard control cabinet over variable frequency?

For applications where variable frequency speed control is not required, the standard control cabinet provides a simpler, more cost-effective solution with reliable pump operation and comprehensive motor protection.
