Johnson and Grundfos circulation pumps

Zantingh is an official dealer of Johnson SPX pumps and also supplies Grundfos circulation pumps for heating and cooling applications. In greenhouse horticulture, heating water must be moved quickly and evenly through the installation. In such cases, flow rate, head, and motor power are decisive for a properly functioning system.

Our range includes Johnson CombiLine in-line circulation pumps with dry motors. These pumps are used in heating installations where continuous and reliable water transport is required. Depending on the installation, we supply versions with various connection sizes, motor powers, installation dimensions, and working pressures. This allows you to choose a pump based on the requirements of the installation.

Grundfos pumps for diverse applications

You can also turn to Zantingh for Grundfos pumps. We supply MAGNA circulation pumps for heating, cooling, geothermal heat pump systems, and domestic hot water. Additionally, we supply Grundfos TP dry-runner pumps for heating, cooling, and tap water installations, as well as for industrial applications.

For smaller installations, Grundfos ALPHA pumps are available. For liquid transport and drainage, we supply Grundfos UNILIFT KP submersible pumps.

Control and adjustment of the pump installation

For a well-regulated pump installation, we also supply Danfoss frequency converters and differential pressure sensors. These allow you to better align the pump with the current demand in the installation. This prevents unnecessary energy consumption and ensures a smoother operating system.

Our pumps are selected based on application, capacity, head, temperature, working pressure, and connection. In doing so, we look at the existing installation and the way the system is used. This ensures you receive a pump that suits your greenhouse, boiler house, or utility installation.

From our stock, we deliver many common types quickly to your location or project. Our advisors are happy to assist you in choosing the right pump, frequency converter, or associated components.
