About Grundfos Pumps and Parts

Grundfos is an international manufacturer of pumps founded in 1945 headquartered in Denmark (Holland, Netherlands). Their first pump was produced in 1946. They have been an industry leader when it comes to innovative technologies with their water pumps. In 1965, the Grundfos submersible pump was the first on the market with stainless steel construction (all other manufacturers were still using cast iron).

What Are the Types of Grundfos Pumps?

  • Drainage & Utility Pumps - These pumps can be used to transport (pump) drain water. Many of these pumps can be used in both permanent and temporary applications (installations). Different size pumps allow for larger or smaller flow capacities.
  • Jet & Well Pumps - Smaller jet pumps can be great for those who have gardens (agricultural and Horticultural projects) or hobbies requiring a water supply. Grundfos well pumps are used for larger applications allowing a quick and easy way to transport water. The Grundfos Jp07s-ci is a trendy jet well pump or try the Jp4-47.
  • Circulating - Also commonly referred to as recirculating or circulation pumps, the UPS model pumps are the most popular Grundfos circulating pumps. These pumps are manufactured for the transportation (circulation) of liquids within your heating and air-conditioning application. These work well with radiant floor heating, boiler applications, pumps for refrigeration units and many other applications.
