How-To Articles


    Grundfos pumps offer the pinnacle of reliability and performance for a large variety of water circulation applications. From home hydronic circulation to large scale commercial water movement, Grundfos has a pump that will provide years of trouble-free service. The UPS26-150F is a three speed circulator with a wet-rotor fluid movement design. Solid cast iron construction guarantees years of reliable performance with minimal maintenance needs, while hardwire electrical connection design allows the pump to tap directly into your home's electrical supply.
  • Durable Cast Iron Construction
  • The Grundfos UPS26-150F is crafted from cast iron, which gives the pump both extended lifespan and protection against corrosion.
  • Whisper Quiet Operation
  • The UPS26-150F pump runs quiet even at high flow levels, ensuring the pump won't distract you from your work or disrupt your sleep.
  • Resilient Wet-Rotor Fluid Movement
  • The wet rotor design of the UPS26-150F lends integrity to both the motor and the rotor itself, providing exceptional longevity to any hydronic system the pump is a part of.
  • Product Note
    Cast iron cannot be used in domestic hot water or potable water applications.
