Description
CVI vertical pump
As the manufacturer of the IPRO line, we design CVI vertical pumps as multistage centrifugal units with in-line ports, intended for pumping clean liquids that are chemically non-aggressive. The series includes models rated from 0.55 to 15 kW, with a head of up to 202 m, depending on the hydraulic range.
Who it's for
- Pumping station installers – we streamline selection within a single series: from the CVI 3 range with DN25–DN32 connections to the CVI 45 with DN80 connections, without changing the installation method.
- Maintenance teams – we supply equipment designed for continuous operation in process circuits, with a clearly specified maximum number of starts per hour.
- Installation designers – we provide the full operating limits: liquid temperature, pH range, and permissible pressure in the system and at the inlet.
- Farms and fish farms – we offer equipment for irrigation systems with a capacity of up to 920 l/min when powered by a three-phase supply.
- Service companies – we provide pumps with noise levels starting at 53 dB(A), which is important in laundries and car washes with staffed workstations.
Applications
- Pressure boosting systems and pumping stations operating with clean water before treatment.
- Industrial installations: washing and rinsing systems, high-pressure circuits, boiler room supply and machine cooling.
- Air conditioning and refrigeration systems, including glycol and coolant transfer.
- Agriculture: sprinkler systems, irrigation systems, watering systems and fish farms.
- Services: laundries, car washes and buildings with high ceilings.
Water supply facilities with three-phase power use CVI 400 V vertical pumps with a capacity of up to 920 l/min.
Features, description and technical data
As the manufacturer of the IPRO line, we build the CVI series as vertical, multistage centrifugal pumps, with the suction and discharge ports positioned horizontally along the same axis (in line). This design allows the unit to be connected directly to existing piping without rerouting it, while the vertical operating position reduces the floor space required in a pumping station or process plant.
Our devices are powered by three-phase, two-pole motors supplied at 3~400 V and 50 Hz, running at 2,850 rpm. The motors have Class F insulation and IP55 protection and are designed for continuous operation. The permitted switching frequency is 100 times per hour for motors rated up to and including 4 kW, and 20 times per hour for motors rated 5.5 kW and above. The sound pressure level LpA ranges from 53 to 75 dB(A), depending on motor power.
W The CVI series hydraulic range comprises models with power ratings from 0.55 to 15 kW, head from 28 to 202 m, and flow rates from 74.5 to 920 l/min, or approximately 4.5 to 55.2 m³/h. Connections are selected according to the hydraulic range: DN25–DN32 for CVI 3 and CVI 5 ranges, DN40 for CVI 10, DN50 for CVI 15 and CVI 20, DN65 for CVI 32, and DN80 for CVI 45. The devices pump clean liquids with no excessive mechanical contamination, that are chemically non-aggressive, at temperatures from 10°C to 90°C and with a pH of 3 to 9, at ambient temperatures up to 40°C.
Materials used:
- Motor housing – AISI 304 stainless steel.
- Suction and discharge casing – ASTM 25B cast iron.
- Pump shaft – AISI 420 stainless steel.
- Impellers and diffusers – AISI 304 stainless steel.
- Cartridge mechanical seal for standard versions, for temperatures from +10°C to 90°C – silicon carbide / tungsten carbide / EPDM.
The CVI series is part of the IPRO line, which we offer for industrial and process applications. The first number in the designation indicates the hydraulic range corresponding to the nominal flow rate in m³/h, while the second indicates the number of pumping stages. Therefore, when selecting a pump, we always refer to the specific duty point, not just the series name. Detailed specifications for each model are provided in the technical data table and product data sheet. W Under Polish operating conditions, we install the devices indoors, protected from freezing, at ambient temperatures up to 40°C.
CVI vertical pumps are technical devices designed for clean liquids and are not water treatment devices. They may be used in installations supplying water intended for consumption only if the intended use of the particular model and the required approvals are specified in its technical documentation. The warranty terms and period are set out in the documentation supplied with the device. If you have any questions, please contact Dambat service.

Frequently asked questions (FAQ) – What are CVI vertical pumps used for?
Where can I buy CVI vertical pumps made by Dambat?
As the manufacturer, we do not sell directly. CVI vertical pumps are available from our sales partners, plumbing and heating wholesalers, and authorized online distributors.
Does Dambat help select a model from the CVI series?
As the manufacturer of the IPRO line, we provide datasheets, performance curves, and operating manuals to help select a unit for the required duty point. Orders are placed through a chosen sales partner, while we provide technical and service support.
What liquids can CVI vertical pumps handle?
We design the CVI series for clean, non-aggressive liquids with a pH of 3 to 9 and a temperature of 10°C to 90°C. W industrial applications, this also includes transferring oil, glycol, and coolant in refrigeration and air-conditioning systems.
What is the difference between CVI pumps and the CVI INOX version?
W the CVI series, the suction and discharge bodies are made of ASTM 25B cast iron, while the impellers, diffusers, and motor housing are made of AISI 304 stainless steel. W the CVI INOX series, all parts in contact with water are made entirely of stainless steel, which is the main design difference between these versions.
What do the numbers in the model name, for example CVI 5-12, mean?
The first number indicates the hydraulic series, corresponding to the nominal flow rate in m³/h, while the second indicates the number of pumping stages, which determines the head achieved. Two models from the same series have similar flow rates but different operating pressures.
How should CVI 400 V vertical pumps be installed?
Install the units vertically, with the suction and discharge connections arranged horizontally in line, in a room with an ambient temperature not exceeding 40°C and protected from freezing. The three-phase power supply 3~400 V, 50 Hz, and motor protection must be set up according to the operating manual.
How many starts per hour are permitted for CVI series pumps?
For motors rated up to and including 4 kW, we allow a maximum of 100 starts per hour; for motors rated 5.5 kW and above, the maximum is 20. More frequent cycles shorten the service life of the mechanical seal and motor, so for systems with variable demand, we recommend using a correctly sized diaphragm tank or variable-speed control.
