Sirio Smart VSD Pump Controller
Sirio Smart VSD Pump Controller – Compact, Intelligent Pressure Control for Any Pump System.
The Sirio Smart VSD Pump Controller is a highly compact and intelligent solution designed to convert virtually any fixed-speed water pump into a fully automated variable speed pressure system. With its advanced inverter technology and integrated pressure sensor, the Sirio Smart dynamically regulates motor speed to maintain constant water pressure — even as demand fluctuates — ensuring energy savings, smoother performance, and reduced mechanical wear.
Perfect for both new systems and retrofitting existing installations, the Sirio Smart can be installed on any compatible single-phase 230V pump up to 2.2kW (3 HP). It is especially effective when paired with a pressure tank, which helps stabilize pressure further and optimize system longevity.
With real-time pressure monitoring, dry-run protection, anti-cycling logic, and user-friendly diagnostics, the Sirio Smart enhances operational efficiency while protecting the pump and plumbing infrastructure. Its compact size allows for direct pump mounting or nearby wall installation, making it ideal for residential, light commercial, irrigation, and tank-fed applications.
Whether you're upgrading an older system or building a new one, the Sirio Smart offers a smart, space-saving, and low-maintenance solution to pressure control.
