CS 65-40-200/5.5 3~400V – horizontal single-stage stainless-steel centrifugal pump
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 provides a capacity of up to 750 l/min while retaining the 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 it is 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 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 is suitable for process-water systems and cleaning systems. It is also used for boiler feed, cooling and air-conditioning systems, condensate transport, and water circulation in swimming-pool systems.
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 suitable pretreatment. The CS 65-40 industrial pump operates in a three-phase system supplied with 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 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 breaks down as follows: DN65 – suction flange diameter, DN40 – discharge flange diameter, 200 – nominal impeller diameter in mm, 11 – motor power in kW.
How does the CS 65-40 differ from the 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 compared with 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 commercial partners, plumbing wholesalers, and authorised online distributors.
Is the IPRO CS 65-40 pump covered by a manufacturer’s warranty?
IPRO – 36 months (3 years) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
