Variable Speed Booster Pump
- Electronically controlled blower/fan motor that can vary it's speed anywhere between it's high and low settings. This allows for multi-stage heating and cooling. The electronic control can detect restrictions to the airflow and adjust the motor speed to always maintain the correct airflow.
- A drive that can change speeds.
- A "smart" motor that runs on DC current and can vary it's operating speed using less electricity and providing increased comfort.
- A pump which maintains positive pressure between the fuel tank and the engine, thus intensifying the flow. Any pump to increase the pressure of the liquid in some part of a pipe circuit.
- A pump for circulating the heat transfer fluid in a hydronic heating system.
- In addition to the filter pump, a booster pump may be necessary to power some automatic pool cleaners.

Merlin Variable Booster Speed Pump
Merlin variable speed pump is designed for the GE Merlin Reverse Osmosis Systems ONLY, manufactured by Aquatec. Most automatic demand pumps are designed for a limited flow range. When variable flows are required (i.e. multiple fixtures drawing fluid from a single source), such pumps require a supplementary accumulator tank, and even then, often experience pressure fluctuations of at least 20 psi. The Aquajet Variable Speed series integrates a state-of-the-art digital controller with our proven 5-valve specialty diaphram pumps. The result is a patend-pending, intelligent pump series which can maintain constant pressures (within 2 psi) for variable flow rates throughout their operating ranges. Utilizing an integrated pressure transducer, these Aquajet pumps monitor any pressure changes and adjust their operating speeds accordingly. Bulky accumulator tanks and unreliable pressure switches are no longer required. 5-valve variable speed pump. Used in applications that require more flow. Comes with a built-in power cord for ease of installation. Quick Disconnect ports - Used in applications that require less flow at higher pressure settings. Comes with a built-in power cord for ease of installation. 115 volt - Flow Rate: .3-3.0 GPM - 65 psi holding constant pressure. At higher flow rate pressure will start to drop.
ABB's dedicated variable speed drive for water
A series of low voltage AC drive modules, dedicated to applications in the water and wastewater sector, is introduced by ABB. The easy-to-install and use ABB industrial drive modules are available from 1.1 to 400 kW in the voltage range 380 to 480 V and are suitable for single pump and parallel pumps systems.
NOTICE: Variable speed limit, next 6 miles
Outside Washington, DC, in Virginia, I95 was regulated by a variable speed limit for a stretch of road work. Presumably the speed limit would be lowered when there were actually workers and raised again when there were none.
