Description
CVI vertical pump
As a manufacturer of the IPRO line, we design CVI vertical pumps as multistage centrifugal units with in-line ports, intended for pumping technically clean, chemically non-aggressive liquids. The series includes models with power ratings from 0.55 to 15 kW and a head of up to 202 m, depending on the hydraulic range.
Who it's for
- Pressure station installers – we streamline selection within a single series: from the CVI 3 range with DN25–DN32 connections to the CVI 45 with a DN80 connection, with no change to 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 all operating limits: liquid temperature, pH range, and the maximum 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 three-phase power.
- Service businesses – we provide pumps with noise levels starting at 53 dB(A), which matters in laundries and car washes with staffed work bays.
Applications
- Pressure-boosting systems and pressure stations operating with technically clean water before treatment.
- Industrial installations: washing and rinsing systems, high-pressure circuits, boiler room supply, machine cooling.
- Air conditioning and refrigeration systems, including glycol and coolant transfer.
- Agriculture: sprinkler systems, irrigation systems, irrigation, fish farms.
- Services: laundries, car washes and facilities with high ceilings.
W facilities with three-phase power, CVI 400 V vertical pumps deliver flow rates of up to 920 l/min.
Features, description and technical data
As a 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 an existing pipeline without rerouting it, while the vertical operating position reduces the floor space needed 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 running at 2850 rpm. The motors have class F insulation and an IP55 protection rating, and are designed for continuous operation. The permitted switching frequency is 100 starts per hour for motors rated up to and including 4 kW, and 20 starts per hour for ratings from 5.5 kW. The LpA sound pressure level ranges from 53 to 75 dB(A), depending on motor power.
W In 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, 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 impurities, that are chemically non-aggressive, at temperatures from 10°C to 90°C and with 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 is part of 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, and 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 in rooms 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 in doubt, please contact Dambat service.

Frequently Asked Questions (FAQ) – What are CVI vertical pumps used for?
Where can I buy Dambat CVI vertical pumps?
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 product data sheets, performance curves and operating instructions to help select a unit for the required duty point. Orders are handled by a selected sales partner, while we provide technical and service support.
What liquids can CVI vertical pumps handle?
We design the CVI series for technically 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 pumping oil, glycol, and coolant in refrigeration and air conditioning systems.
How do CVI pumps differ from the CVI INOX versions?
W the CVI series, we make the suction and discharge casings from ASTM 25B cast iron, and the impellers, diffusers, and motor housing from AISI 304 stainless steel. W the CVI INOX series, all parts in contact with water are made entirely of stainless steel, which is the key design difference between the two versions.
What do the numbers in the 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 pumping stages, which determines the head achieved. Two models in 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 ports arranged horizontally in an in-line configuration, in a room with an ambient temperature not exceeding 40°C and protected against freezing. The three-phase 3~400 V, 50 Hz power supply and motor protection must be installed in accordance with the operating instructions.
How many starts per hour are allowed 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, 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 sized pressure tank or variable speed control.
