API 25-60/180 PWM – circulating pump
The IPRO API series comprises energy-efficient electronic circulating pumps equipped with a PWM frequency converter and an electronic processor that automatically controls the device. This solution provides an energy efficiency index of EEI ≤ 0.23, while 8 operating modes allow the pump’s performance characteristics to be precisely matched to system requirements.
Who it's for
-
Central heating and solar system installers – ready to install, with a 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, allow the pump’s performance characteristics to be precisely matched to project requirements while using very little energy.
-
Investors and developers – significantly lower electricity consumption compared with conventional pumps reduces heating system operating costs.
-
Maintenance teams and service technicians – simple operating mode configuration and no need for additional external motor protection make operation easier.
Applications
The IPRO API series is designed to circulate liquids in central heating systems and solar installations. Its temperature range of 2°C to 110°C allows safe operation in constant-temperature heating systems with variable flow, systems with variable pipe temperatures and night mode, as well as air conditioning systems and industrial circuits.
The electronic processor with frequency converter automatically adjusts output to the system’s current needs, eliminating the need for manual adjustment. W The pump comes with a set of unions and a power cable, reducing installation and startup time.

Frequently asked questions (FAQ) – IPRO API PWM series circulation pumps
What are API circulation pumps used for, and what types of installations can they be used in?
API pumps are designed to circulate fluid in central heating installations and solar systems. They are suitable for heating systems with variable flow, systems with night mode, air conditioning systems, and industrial circuits. The fluid temperature range is 2–110°C.
What does PWM mean in the API pump name, and what advantage does it offer?
PWM (pulse-width modulation) is a control signal that allows the pump to work with external controllers and installation regulators. The built-in frequency converter, combined with an electronic processor, can reduce power consumption to 1/10–1/3 of that of conventional pumps, significantly lowering operating costs.
How many operating modes does the API pump have, and how do I set them?
All 7 API pump models have 9 operating modes to choose from, depending on the installation requirements. Available modes include proportional pressure, constant pressure, and constant speed curves. Select the mode according to the user manual supplied with the device.
Where can I buy a Dambat API circulation pump?
Dambat does not sell directly to customers. API series pumps are available from our sales partners, plumbing and heating wholesalers, and authorized online distributors.
What are the warranty terms, and where can I get my API pump serviced?
API series pumps are covered by a 36-month (3-year) manufacturer’s warranty from Dambat, starting 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).
