CS 65-50-200/11 3~400V – horizontal single-stage stainless steel centrifugal pump
The IPRO CS 65-50 pump is a horizontal, single-stage centrifugal pump in a monoblock design, made of stainless steel using cold-forming and hydroforming technology. The 2" discharge flange ensures a high flow rate of up to 1166 l/min while maintaining a compact monoblock design. The series is available exclusively in a three-phase version, with a wide power range from 3 to 18.5 kW.
Who it is for
-
Large industrial plants – a flow rate of approximately 750–1166 l/min can supply extensive industrial installations, boiler rooms, and cooling systems in larger manufacturing plants.
-
Large apartment buildings and commercial facilities – the high flow capacity is well suited to booster sets serving residential developments, hotels, and large office buildings.
-
Fire protection system installers – high flow capacity and head make it suitable for larger pressure-boosting systems and hydrant installations.
-
Large-scale agriculture – the pump handles irrigation of extensive crops and large installations on fish farms.
Applications
The IPRO CS 65-50 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 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 65-50 industrial pump operates in a three-phase system supplied with 3~230 V or 3~400 V.
CS 65-50 features – design and technical data
The impeller, shaft, and pump cover of the CS 65-50 are made of AISI 304 stainless steel (an AISI 316 shaft is available upon 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 65-50 cover a power range from 3 to 18.5 kW. The 3 kW model is powered at 230 V (delta) / 400 V (star), while the 4 kW and higher models are powered at 400 V (delta) / 690 V (star). Efficiency and the cos φ power factor increase with motor power:

Frequently asked questions (FAQ) – CS 65-50 horizontal pump
What applications is the CS 65-50 pump suitable for?
The IPRO CS 65-50 pump is used for water supply, process water systems, boiler feed, cooling and air-conditioning systems, and large-scale agricultural irrigation.
What do the numbers in the CS 65-50-200/18.5 model name mean?
The designation breaks down as follows: DN65 – suction flange diameter, DN50 – discharge flange diameter, 200 – nominal impeller diameter in mm, 18.5 – motor power in kW.
How does the CS 65-50 differ from the CS 65-40?
The CS 65-50 has a larger discharge flange (DN50 versus DN40) and a wider motor power range (up to 18.5 kW versus 11 kW), resulting in higher capacity – up to 1166 l/min versus 750 l/min for the CS 65-40.
Can the CS 65-50 pump 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 I buy the CS 65-50 horizontal pump?
Dambat does not sell directly. The CS 65-50 pump is available from our trade partners, installation wholesalers, and authorized online distributors.
Is the IPRO CS 65-50 pump covered by the manufacturer’s warranty?
IPRO – 36 months (3 years) of manufacturer’s warranty. Dambat provides warranty and post-warranty service.
