CS 65-40-160/4 (4 kW, 400V) industrial centrifugal pump

CS 65-40-160/4 3~400V – horizontal single-stage centrifugal pump made of stainless steel

The IPRO CS 65-40 is a horizontal, single-stage centrifugal pump with a monoblock design, made of stainless steel using cold-forming and hydroforming technology. The DN65 suction flange ensures a capacity of up to 750 l/min while retaining the compact monoblock design. The three-phase version covers the full power range available in this flange size, from the smallest to the highest-capacity variants.

For whom

• Large apartment buildings and commercial facilities – a flow rate of approximately 500–750 l/min can serve large apartment buildings, hotels, or larger office facilities.
• Industrial plants – higher-power variants ensure stable operation in boiler feed systems and industrial cooling and air-conditioning systems.
• Installers of pressurization and fire protection systems – the monoblock design and high capacity facilitate use in larger pressurization sets and pressure-boosting systems.
• Large-scale agriculture – the pump handles irrigation of larger cultivated areas and installations on fish farms requiring higher capacity.

Applications

The IPRO CS 65-40 pump is designed to transport water and increase pressure in raw-water intake and discharge systems; use in water supply systems is permitted only in accordance with the technical documentation for the specific model. In industrial applications, it performs well in process-water and cleaning systems. It is also used for boiler feed, in cooling and air-conditioning systems, for condensate transport, and in water circulation systems for swimming pools.

In agriculture, the pump handles irrigation of agricultural land and installations on fish farms. The standard mechanical seal is not suitable for liquids containing solid particles—the pump is intended exclusively for clean media. The pump is not a water treatment device—when using it for other purposes, we recommend ensuring appropriate pretreatment. The CS 65-40 industrial pump operates in a three-phase system powered by 3~230 V or 3~400 V.

CS 65-40 features – design and technical data

The impeller, shaft, and pump cover of the CS 65-40 are made of AISI 304 stainless steel (an AISI 316 shaft is available on request). The standard mechanical seal consists of graphite / ceramic / NBR—a solution suitable for clean liquids and not intended for operation with solid contaminants. The O-ring is made of NBR.

The motors driving the CS 65-40 cover a power range from 1.5 to 11 kW. Models up to 3 kW are powered at 230 V (delta) / 400 V (star), while models rated 4 kW and above are powered at 400 V (delta) / 690 V (star). Efficiency and the power factor cos φ increase with motor power:

• Capacity: 500–750 l/min depending on the variant
• Max. head: 21–69 m depending on the variant
• Insulation class: F
• Protection rating: IP55
• Pumped liquid temperature range: -20°C to 70°C (104°C on special order)
• Max. ambient temperature: 40°C
• Max. system pressure: 10 bar
• Flanged connection: DN65 (suction) x DN40 (discharge)
• Rotational speed: 2900 rpm
