COLP 4-250 T (0.25 kW, 400 V) – submersible coolant pump
IPRO COLP pumps are submersible pumps designed for pumping coolant, oils, and cutting emulsions in machine tools and machines requiring forced circulation of a cooling medium. The extended shaft design allows the pump to be immersed in a coolant tank without risking damage to the motor seal, which is a risk with conventional pumps operating in direct contact with oils and emulsions. The stainless steel impeller and shaft provide corrosion resistance during prolonged operation in workshop environments.
Who it's for
-
Mechanical workshops and machining facilities – the COLP pump provides forced coolant circulation in CNC and conventional machining centers.
-
Metallurgical and manufacturing plants – the wide capacity range (from 33 to 133 l/min) makes it easy to select a pump for coolant tanks of different capacities.
-
Service centers and maintenance departments – the extended shaft design makes servicing easier without having to fully dismantle the installation.
-
Facilities using oils and cutting emulsions – the stainless steel impeller and shaft ensure durability during constant contact with oils, emulsions, and other lubricating and cooling fluids.
Applications
IPRO COLP pumps are designed for pumping coolant, cutting emulsions, and oils in machine tools, as well as in all machines requiring forced circulation of a cooling medium. The pump is used in grinders, lathes, and CNC milling machines, as well as automated production lines where uninterrupted coolant recirculation is required.
These pumps are ideal for machining lines where continuous coolant circulation affects machining quality and cutting tool life. The series handles fluids with a viscosity of up to 150 mm²/s and contaminants up to 0.5 mm in diameter, making it suitable for both clean emulsions and higher-density oils. The COLP industrial pump operates on a three-phase supply at 3~230 V or 3~400 V.
COLP features – description and technical data
The COLP pump motor has an IP55 protection rating and Class F insulation, providing resistance to splashes, dust, and moisture typical of production halls and machining stations. Continuous operation (S1) allows the pump to support the machining process without interruption, with no need for periodic shutdowns.
The series includes eight models grouped into four power classes - 60 W, 100 W, 150 W, and 250 W - differing in hydraulic capacity and immersion depth in the coolant tank. All models are equipped with a three-phase motor designed to operate with both 230V power supply (delta connection) and 400V power supply (star connection).

Frequently Asked Questions (FAQ) - COLP coolant pump
What machine tools and machines is the COLP pump suitable for?
The IPRO COLP pump is used in CNC machine tools, conventional machining centers, and all types of machines that require forced circulation of coolant, cutting emulsions, or oils.
What viscosity of medium can the COLP pump?
The COLP pump is designed for media with a viscosity of up to 150 mm²/s and contaminants no larger than 0.5 mm in diameter, allowing it to handle both cooling emulsions and higher-viscosity oils.
Why does the COLP pump have an extended shaft?
The extended shaft moves the motor seal away from direct contact with the pumped medium. W In conventional submersible pumps, oils and coolants can damage the motor seal - the COLP design eliminates this risk, extending the pump's service life.
How do I choose the right COLP series model for my installation?
The choice of model depends primarily on the required pumping capacity and the depth of the coolant tank in the machine. When choosing, we recommend considering the maximum head and flow rate required for the specific installation. W If you have any questions, please contact our technical department, which will help you make the right decision.
Where can I buy a COLP coolant pump?
Dambat does not sell directly. The COLP pump is available from our business partners, plumbing and installation wholesalers, and authorized online distributors.
Is the IPRO COLP pump covered by the manufacturer's warranty?
IPRO - 36 months (3 years) manufacturer's warranty. Dambat provides warranty and post-warranty service.
