The Grundfos UPS15-50 Selectric and UPS15-60 Super Selectric circulators are designed to cater for the majority of domestic wet central heating systems upto 120,000 btu's/hr. The UPS15-50 Selectric covers virtually all standard systems, whilst the higher head UPS15-60 can accommodate larger domestic systems. The pumps incorporate an energy saving three speed motor for pump to system matching and consequent reduction of hydraulic noise. The very highest quality pump components provide long life and maximum resistance to corrosion. Standard port to port dimensions make these pumps interchangeable when replacing the vast majority of old pumps.
