Nautis
VSF Pump

Introducing Nautis™ VSF, the first and only adaptive flow pump for swimming pools and spas.

We’re taking the guess work out of energy saving. The Nautis™ VSF Pump from H2flow Controls is the first and only pump capable of adapting the speed of the motor based on an accurate flow measurement. Setting the motor speed based on the flow rate allows you to achieve the maximum possible energy savings!

An Adaptive Flow, Self-Priming Pump

The Nautis™ VSF optimizes every aspect of pool pump ownership. While Nautis™ VSF is the only available pump to feature adaptive flow control using Eco-Flow® technology, it’s also a convenient drop-in replacement for both Hayward® Super Pump® and Pentair® SuperFlo® and WhisperFlo®.

Key Features

  • The only pump featuring Eco-Flow® technology, allowing for constant flow functionality.

  • Easily serviceable 4-bolt design & handle.

  • Lid lock ring that incorporates handles, providing the user with a convenient way to easily remove the lid.

  • Suction and Discharge come equipped with quick disconnect unions as well as internal threads for easy installation and maintenance.

  • Every pump is wet tested before leaving the factory.

  • All models are equipped with an LED light in the basket lid, for ease of maintenance.

  • Discrete switch inputs, for easy connection to automation.

  • Ability to run dry for up to an hour.

  • Available riser for direct replacement of WhisperFlo® and IntelliFlow® models.

Key Benefits

Maximized Energy Saving Potential

Optimizing pump speed and heater usage based on the flow rate typically results in significant energy savings.

Reduced Equipment Wear

Running the motor at the required speed - and not unnecessarily exceeding it - will result in prolonged equipment life.

Optimal Chemical Usage

If the speed is set too high, unnecessary chemical usage occurs. With Nautis™ VSF, the speed is optimized, meaning chemical usage is, too.

Adapts to Changing Conditions

In an effort to maintain constant flow, Nautis™ VSF will sense - and adapt to - dirty filters and other conditions that reduce the flow rate.

The New Revolution in Variable Speed

When you combine the power of a Nautis™ variable speed pump with the accuracy of FlowVis® - the industry’s most accurate and reliable flow meter - the result is something truly revolutionary.

Traditional variable speed pumps are often times programmed using a preset - or default - speed setting. This is problematic because no two plumbing configurations are the same, and pools can vary greatly in size. The result is lost energy savings, unnecessary equipment wear, dirty pools, and inefficient chemical circulation.

Nautis™ VSF changes all of this. Knowing the flow rate allows the user to set the speed based on accurate flow data and on meeting turnover requirements, not on guess work. Furthermore, Nautis™ VSF will identify changes in conditions - such as a dirty filter - and adapt the motor speed accordingly, to maintain constant flow.
