Pumping equipment electric motors ZDB-71K-30 kW-220V-IP23

1. Highly reliable, dedicated heavy duty pump design

This motor belongs to the ZDB series of specialized DC motors for industrial pumps, model ZDB-71K. Rated power 30 kW, rated voltage 220 V, operating mode S1 (continuous), rated rotation speed 3000 rpm. Designed specifically to drive pumps in metallurgical, petrochemical and hydraulic systems. Capable of withstanding long-term pulsating loads, continuous operation and shock loads during starts/stops, being a key component, the “heart” of pumping equipment.

2. Self-ventilated cooling system IC01, adapted for conditions without external cooling

The IC01 self-ventilating design is used with a built-in fan driven directly by the motor shaft. Cooling efficiency is automatically adjusted depending on the rotation speed. No external cooling fan is required and the design does not contain unnecessary elements. The engine is directly adapted to installation conditions in pumping stations and workshops without external sources of compressed air/electric power, eliminating additional points of equipment failure and simplifying system configuration.

3. IP rating 23 + cast iron body, resistance to industrial interference

The IP23℃of protection provides protection against industrial dust, oil splashes and light water spray, while maintaining effective ventilation of the windings. The high-strength cast iron housing has high rigidity, absorbs vibrations and shocks during pump operation, reduces the risk of resonance, extends the life of the engine and adapts it to difficult operating conditions in metallurgical and petrochemical shops.

4. IM V1 vertical flange mount for direct pump integration

Vertical flange mounting according to IM V1 standard is used. The flange interface corresponds to the standards of most pumping units, which allows for a direct motor-pump connection. Minimal misalignment and high transmission efficiency eliminate coupling losses and also save horizontal installation space, adapting to the compact vertical layout of pumping and hydraulic stations.

5. High quality electrical insulation and excitation system for stable continuous operation

The armature winding is made of insulating materials of heat resistance class F, capable of withstanding temperature loads and voltage fluctuations during long-term operation at full power. It is highly resistant to aging and corona discharge, ensuring insulation reliability in accordance with the requirements of industrial continuous operation.

The independent excitation system provides stable and adjustable excitation current, sufficient starting torque and smooth speed control characteristics. Adapts to changes in pump load from idle to full load, ensuring stable supply pressure without fluctuations.

An optimized commutation system with high precision carbon brush and commutator selection ensures low sparking and even brush wear at high speeds of 3000 rpm, reducing shutdowns due to commutation problems.

6. Imported bearings and convenient lubrication system to reduce the complexity of maintenance

The front and rear ends are equipped with imported SKF 6310/C3 and 6309/C3 bearings with high radial and axial load capacity, adapted to load fluctuations during pump operation. Supplied with multi-purpose lithium grease and clear addition and maintenance instructions. The bearing chamber design makes it easy to add lubrication on site, extends service intervals and reduces frequent disassembly and repair work.

1. Stable continuous operation for smooth production

The motor is designed for continuous S1 mode and operates stably at long-term full load without overheating and insulation aging. Eliminates downtime -due to frequent repairs of pump drives, ensures reliable power supply in metallurgical and petrochemical plants.

2. Direct drive with high efficiency, reducing energy losses

The vertical mounting design of IM V1 eliminates intermediate transmission elements, the efficiency is close to 100%. Reduces mechanical losses compared to clutch drive, increases overall pump performance and reduces operating energy costs.

3. No external cooling, suitable for difficult installation conditions

The IC01's self-ventilated design does not require additional fans. Suitable for installation in pumping and hydraulic stations without auxiliary cooling media. Eliminates stoppages -due to breakdowns of external equipment, reduces costs for laying communications and maintenance.

4. Minimal maintenance and long service life, saving operating costs

Imported bearings and an improved commutation system increase the intervals between service work, and the lubrication procedure is simple. High factory quality ensures long-term trouble-free operation, significantly reduces maintenance costs and losses from equipment downtime.

5. High compatibility with 220V DC network

The rated voltage of 220 V allows direct connection to industrial power supplies and rectifier units without additional converters. Minimal losses in wires and stable power supply eliminate unnecessary costs and risks of breakdowns of converter equipment, ideal for DC systems in the metallurgical industry.
