SundanceŽ JacuzziŽ Spas Circulation Pumps From the mid 90's Sundance went to a Circulation Pump System on their 800/850/750 Series. They called the system "Permaclear". Sundance first used Grunddfos Pumps then went to Laing and later diversified into several different Circulation Pumps. JacuzziŽ has been using the same system in their spas from the 2000's to today.
