API 25-40/180 PWM – circulator pump
The API series consists of energy-efficient electronic circulator pumps by IPRO, equipped with a PWM frequency converter and an electronic processor that automatically controls the unit’s operation. This solution achieves an energy efficiency index of EEI ≤ 0.23, while 8 operating modes allow the pump characteristics to be precisely matched to system requirements.
Who is it for?
-
Central heating and solar system installers – ready-to-install unit supplied with a set of union fittings 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 characteristics to be precisely matched to project requirements while using very little energy.
-
Investors and developers – significantly lower electricity consumption compared to conventional pumps reduces the operating costs of the heating system.
-
Maintenance departments and service technicians – simple operating mode configuration and no need for additional external motor protection make operation easier.
Applications
The API series by IPRO is designed to circulate liquids in central heating systems and solar systems. 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 a frequency converter automatically adjusts output to the current needs of the system, eliminating the need for manual adjustment. W set with the pump includes a set of union fittings and a power cable, reducing installation and commissioning time.

Frequently Asked Questions (FAQ) – IPRO API PWM series circulation pumps
What are API circulation pumps used for, and which installations can they be used in?
API pumps are designed to circulate liquid 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 liquid 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 installation controllers and regulators. The built-in frequency converter, together with an electronic processor, reduces power consumption to 1/10–1/3 of that typical 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 offer 9 operating modes to suit installation requirements, including 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. 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 a.m.-3:30 p.m.).
