Description
CVI vertical pump
As the manufacturer of the IPRO range, we design CVI vertical pumps as multistage centrifugal units with in-line ports, intended for pumping clean, chemically non-aggressive liquids. 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
- Pressure-boosting station installers – we simplify 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 the maximum number of starts per hour clearly specified.
- Installation designers – we provide the full range of operating limits: liquid temperature, pH range, and the permissible pressure in the system and at the inlet.
- Farms and fish farms – we offer equipment for irrigation systems with flow rates of up to 920 l/min on a three-phase supply.
- Service companies – we offer pumps with noise levels from 53 dB(A), which is important in laundries and car washes with staffed service bays.
Applications
- Pressure-boosting systems and pressure-boosting stations handling clean water before treatment.
- Industrial systems: washing and rinsing systems, high-pressure circuits, boiler house supply and machine cooling.
- Air conditioning and refrigeration systems, including glycol and coolant transfer.
- Agriculture: sprinkler irrigation systems, irrigation systems, water supply systems and fish farms.
- Services: laundries, car washes and facilities with high-rise buildings.
Where three-phase power is available, CVI 400 V vertical pumps operate at flow rates of up to 920 l/min.
Features, description and technical data
As the manufacturer of the IPRO range, we build the CVI series as vertical, multistage centrifugal pumps, with the suction and discharge ports arranged horizontally on the same axis (in line). This design allows the unit to be connected directly to existing pipework without rerouting it, while the vertical operating position reduces the space it takes up in a pressure-boosting station or process plant.
Our devices are driven by three-phase, two-pole motors powered by 3~400 V at a frequency of 50 Hz and operating at 2,850 rpm. The motors have class F insulation and an IP55 protection rating 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 LpA sound pressure level ranges from 53 to 75 dB(A), depending on motor power.
W terms of hydraulics, the CVI series includes 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 series: DN25–DN32 for CVI 3 and CVI 5 series, 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 without excessive mechanical impurities, which are chemically non-aggressive, with a temperature of 10°C to 90°C and a pH of 3 to 9, at an ambient temperature of 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, from +10°C to 90°C – silicon carbide / tungsten carbide / EPDM.
The CVI series belongs to the IPRO line, which we offer as a solution for industrial and process applications. The first number in the designation indicates the hydraulic series 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 consider 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 Polish operating conditions, we install the devices indoors, protected from freezing, with an ambient temperature of 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 drinking water systems only if the intended use of the specific model and the required approvals are specified in its technical documentation. The warranty terms and period are specified 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 manufactured by Dambat?
As the manufacturer, we do not sell directly. CVI vertical pumps are available from our sales partners, plumbing wholesalers, and authorized online distributors.
Does Dambat help select a model from the CVI series?
As the manufacturer of the IPRO line, we provide product data sheets, performance curves, and operating manuals to help select a unit for the required duty point. Orders are placed through a selected sales partner, while we provide technical and service support.
What liquids can CVI vertical pumps handle?
We design the CVI series for clean, chemically 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 structural difference between these versions.
What do the numbers in a model name mean, for example, CVI 5-12?
The first number indicates the hydraulic series, corresponding to the nominal flow rate in m³/h, while the second indicates the number of pump stages, which determines the delivery head. Two models in the same series have similar capacities 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 where the ambient temperature does not exceed 40°C and that is protected against freezing. The three-phase 3~400 V, 50 Hz power supply and motor protection must be installed in accordance with the operating manual.
How many starts per hour are CVI series pumps rated for?
For motors rated up to and including 4 kW, we allow a maximum of 100 starts per hour, and for ratings of 5.5 kW and above, a maximum of 20. More frequent cycling shortens the service life of the mechanical seal and motor, so for systems with variable demand, we recommend using a suitably selected diaphragm tank or speed control.
