Taco’s now-expanded ECM, wet rotor Viridian line includes the VR3452 high efficiency wet rotor variable speed circulator for chilled and hot water applications, offering up to 34 feet of shut-off head and 52 gpm flow. All settings are accomplished with the user-friendly interface. The permanent magnet ECM motor saves up to 85% of the electrical energy compared to conventional pumps.
The circulator offers:
• Auto mode (default)
• Proportional pressure control
• Constant pressure control
• Constant speed
• Night setback turndown
• Available in 115 or 230 volts
The optional communication module provides: Ethernet and Modbus RTU communication, analog control input 0 – 10 V, three analog inputs/outputs, one relay output, main and standby operation.

Taco’s John White Jr. announces strategic collaboration with Askoll, Italian pump manufacturer. New Viridian circulator based on Askoll ECM technology.
CRANSTON, R.I. — As guests from the media, employees and state and Italian officials gathered at its Innovation and Development Center, Taco, Inc. announced a strategic partnering agreement with Askoll, an Italian manufacturer of pumps used in a variety of industries.
Under the terms of the agreement, the two companies will collaborate on research and development relating to new circulating pump designs and other joint product and marketing initiatives.
Elio Marioni, Askoll President
“Taco’s path for future growth lies in strategic relationships with world-class companies like Askoll,” said John Hazen White, Jr., Taco President and CEO. “We have longed searched the world for the best suppliers of castings and raw materials for our products, and now we are doing the same for the best and brightest technology partners. We look forward to a long and mutually beneficial working relationship with Askoll.”
Taco has already begun assembling a new high efficiency circulator for residential and light commercial applications — the VR1816 — which employs Askoll’s variable speed technology, at its Cranston, R.I. plant, and the future calls for the VR1816 to be manufactured entirely by Taco.
The VR1816 is an extension of Taco’s Viridian line of circulators, which is a wet rotor circulator with an ECM permanent magnet motor that uses up to 85% less electricity. It features an infinitely variable speed setting capability for fine-tuning the flow of any hydronics-based system, and six pressure presets to fit the job.
Askoll, headquartered in Dueville, Italy, employs some 3,000 people in 11 companies focusing on advanced electric-motored pumps that are used in aquariums, ponds and terrariums, industrial automation, heating, and home appliances. The company was founded in 1978 by Elio Marioni.
“We are proud and excited to have embraced this new professional opportunity with Taco, a strong and serious company that shares our view and ethics. Askoll believes in technological evolution and always strives for innovation,” said Elio Marioni, Askoll President. “Innovation is in our DNA. In 30 years we have registered over 800 patents and developed a company fully dedicated to research. Our mission is to reduce raw materials and energy waste and to increase the performance of domestic appliance and heating systems, thereby contributing to environmental sustainability and people well-being.”
