API 25-40/180 PWM – circulation pump
The API series consists of energy-efficient electronic circulation pumps by IPRO, equipped with a PWM frequency converter and an electronic processor that automatically controls the device’s operation. Thanks to this solution, the energy efficiency index is EEI ≤ 0.23, while the 8 operating modes allow the pump’s performance curve to be precisely matched to the requirements of the installation.
Who it is for
-
Installers of central heating and solar systems – a ready-to-install device supplied with a complete set of unions and a power cable; PWM signal support enables operation with external controllers and regulators.
-
Heating system designers – 9 operating modes, including proportional- and constant-pressure curves, enable precise selection of the pump’s performance curve to meet project requirements while using very little energy.
-
Investors and developers – a significant reduction in electricity consumption compared with conventional pumps translates into lower operating costs for the heating system.
-
Maintenance departments and service technicians – simple configuration of operating modes and no need for additional external motor protection make operation easier.
Application
The IPRO API series is designed to force liquid circulation in central heating systems and solar systems. The temperature range from 2°C to 110°C enables safe operation in constant-temperature heating systems with variable flow, systems with varying pipe temperatures and night mode, as well as in air-conditioning installations and industrial circuits.
The electronic processor with a frequency converter automatically adjusts the output to the current needs of the installation, eliminating the need for manual adjustment. The pump is supplied with a complete set of unions and a power cable, reducing installation and commissioning time.

Frequently asked questions (FAQ) – IPRO API PWM circulation pumps
What are API circulation pumps used for, and in which systems can they be used?
API pumps are designed to force liquid circulation in central heating systems and solar systems. They are suitable for heating systems with variable flow, systems with night mode, air-conditioning systems, and industrial circuits. The liquid temperature range is 2–110°C.
What does PWM mean in the name of API pumps, and what advantage does it provide?
PWM (pulse-width modulation) is a control signal that enables the pump to operate with external system controllers and regulators. The built-in frequency converter, combined with the electronic processor, can reduce power consumption to 1/10–1/3 of the level typical of conventional pumps, significantly lowering operating costs.
How many operating modes does the API pump have, and how are they set?
All 7 API pump models offer 9 operating modes selected according to the requirements of the installation – proportional-pressure, constant-pressure, and constant-speed curves are available. The mode is selected according to the operating instructions supplied with the device.
Where can I buy a Dambat API circulation pump?
Dambat does not sell directly. API series pumps are available from our commercial partners, plumbing wholesalers, and authorized online distributors.
What are the warranty terms, and where can the API pump be serviced?
API series pumps are covered by a 36-month (3-year) Dambat manufacturer’s warranty, calculated from the purchase date confirmed by the original proof of purchase. Warranty and post-warranty service is provided by Dambat, Adamów 50, Grodzisk Mazowiecki. Contact: tel. +48 22 632 86 09, email: serwis@dambat.pl (Mon–Fri, 8:00–15:30).
