FAQS

  1. What is the difference between a gerotor pump and a gear pump?

    While both gerotor pumps and gear pumps operate on the same principle of positive displacement, there are some critical differences between the two. A gear pump typically has a higher efficiency rating and can handle viscous fluids better than a gerotor pump. Additionally, this specific Danfoss SEP1NN 4,3 Gear Pump offers higher pressures and greater accuracy for more precise pressure control than a gerotor pump.

  2. What is the max working temperature for the Danfoss SEP1NN 4,3 Gear Pump?

    The Danfoss SEP1NN 4,3 Gear Pump has a maximum working temperature of 100 degrees Celsius (212 degrees Fahrenheit). The gear pump is designed to operate at temperatures that are safe and comfortable for their operators.

  3. What is the maximum operating pressure for the Danfoss SEP1NN 4,3 Gear Pump?

    The Danfoss SEP1NN 4,3 Gear Pump has a maximum operating pressure of 420 bar (6,100 psi). The pump is designed to operate at temperatures up to 70°C (158°F) and is rated for continuous duty pressure cycles up to 300 bar.

  4. What is the maximum operating temperature for the Danfoss SEP1NN 4,3?

    The maximum operating temperature for the Danfoss SEP1NN 4,3 Gear Pumps is 140°C. It is also hermetically sealed, making it ideal for use in extreme environments. This pump can operate at up to 400 bar pressure, making it suitable for many different applications.
