CS 65-50-200/15 3~400V – horizontal single-stage stainless steel centrifugal pump
The IPRO CS 65-50 is a horizontal, single-stage centrifugal pump in a monoblock design, made of stainless steel using cold stamping and hydroforming technology. The 2" discharge flange ensures a high capacity of up to 1166 l/min while maintaining the 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 – its high capacity is well suited to booster sets serving housing estates, hotels, and large office buildings.
-
Fire-protection system installers – high 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 at 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 given model. In industrial applications, it performs well in 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 is used for irrigating agricultural land and in fish-farming installations. 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 65-50 industrial pump operates in a three-phase system powered by 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 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 65-50 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 suitable 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) manufacturer’s warranty. Dambat provides warranty and post-warranty service.
