Circulation Pump Perfecta aPump+ 25U-6-130

Optimize your heating system's efficiency and slash your electricity bills with the Perfecta aPump+ 25U-6-130. 

This high-efficiency, electronically controlled circulation pump is specifically designed for residential water-borne radiator systems and underfloor heating networks. Supporting a maximum flow rate of up to 4 m³/h, the pump easily manages heating sources up to approximately 70 kW at a Delta-T of 20°, making it the ideal selection for budget-minded homeowners.

Intelligent capacity regulation and factory presetting
The Perfecta aPump+ is equipped with stepless capacity regulation that automatically balances its output according to the property's real-time heating demand. The pump arrives factory-preset for standard residential radiator setups featuring proportional pressure control—the most energy-efficient operating profile available. As system thermostatic valves close, the pump slows down its RPM automatically. The integrated digital screen provides complete clarity by displaying current power consumption in real-time.

Heavy-duty build and simple air venting
The pump is built to withstand demanding conditions, featuring a robust pump housing manufactured from cataphoretically coated cast iron to provide superior corrosion resistance. This premium mechanical architecture includes a ceramic shaft and an impeller made from durable composite material. It is completely jam-proof, utilizing an automatic restart function that removes the need for external motor overload protection. Thanks to the integrated mechanical brass air screw, purging air from the loop manually during setup or seasonal startups is exceptionally simple.

Slick installation and elite ErP compliance
Featuring a compact port-to-port dimension of 130 mm and a standard G1½" (DN25) male thread layout, the pump is incredibly straightforward to mount, even within tightly configured plumbing manifests or inside heat pump cabinets. It arrives with a 2-meter pre-wired power cable to secure a quick and trouble-free grid connection. The appliance fully conforms to the strict EU ErP directive, boasting a remarkably low Energy Efficiency Index (EEI < 0.18), guaranteeing low environmental impact and maximized financial savings.

Product Benefits:

• Extremely energy efficient: High-efficiency engineering with an index of EEI < 0.18 minimizes electricity consumption.
• Proportional modulation: Automatically self-regulates RPM against pipe resistance for optimized system operation.
• Clear digital interface: Monitors current power absorption in watts in real-time for simple diagnostics.
• Effortless manual venting: Built-in brass air screw allows for fast and uncomplicated system commissioning.
• Premium corrosion shielding: Cataphoretically coated cast iron housing guarantees an extended operational lifespan.
• Anti-blocking protection: Automated restart software sequences remove the need for external motor protection.
