CS 65-40-200/11 3~400V – horizontal single-stage centrifugal pump made of stainless steel
The IPRO CS 65-40 pump is a horizontal, single-stage centrifugal pump with a monoblock design, made of stainless steel using cold pressing and hydroforming technology. The DN65 suction flange ensures a capacity of up to 750 l/min while maintaining a compact monoblock design. The three-phase version covers the full power range available for this flange size, from the smallest to the highest-capacity variants.
Who is it for
-
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 pressure-boosting and fire-protection systems – the monoblock design and high capacity facilitate use in larger pressure-boosting sets and pressure-increase systems.
-
Larger-scale agriculture – the pump handles irrigation of extensive crops 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; its use in water supply installations is permitted only in accordance with the technical documentation for the specific model. In industrial applications, it performs well in process water systems 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 designed 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 is a graphite / ceramic / NBR combination—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 at 4 kW and above are powered at 400 V (delta) / 690 V (star). Efficiency and the power factor cos φ increase with motor power:

Frequently asked questions (FAQ) – CS 65-40 horizontal pump
What applications is the CS 65-40 pump suitable for?
The IPRO CS 65-40 pump is suitable for water supply, process water systems, boiler feed, cooling and air-conditioning systems, and agricultural irrigation.
What do the numbers in the CS 65-40-200/11 model name mean?
The designation consists of: DN65 – suction flange diameter, DN40 – discharge flange diameter, 200 – nominal impeller diameter in mm, 11 – motor power in kW.
What is the difference between the CS 65-40 and CS 50-32?
The CS 65-40 has a larger suction flange (DN65 versus DN50) and discharge flange (DN40 versus DN32), as well as a wider motor power range (up to 11 kW versus 7.5 kW), resulting in higher performance – up to 750 l/min versus 416 l/min for the CS 50-32.
Can the CS 65-40 pump handle liquids containing solid contaminants?
No – the standard mechanical seal (graphite/ceramic/NBR) is intended exclusively for clean liquids without solid particles. Contaminated media require a different seal, available on request.
Where can the CS 65-40 horizontal pump be purchased?
Dambat does not sell directly. The CS 65-40 pump is available from our trade partners, installation wholesalers, and authorised online distributors.
Is the IPRO CS 65-40 pump covered by the manufacturer’s warranty?
IPRO – 36 months (3 years) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
