The New Davey Dynadrive Variable Speed Household Pump
15th Aug 2019
DynaDrive is the latest all in one home pressure system. Variable speed drive maintains water pressure at a fixed point regardless of an increase or decrease in water demand for your household. The number of taps being used in your home doesn't impact your water pressure or flow, with DynaDrive keeping pressure constant and steady.
The DynaDrive System consists of a pump, pressure tank and a controller to maintain the desired performance.
User Benefits:
- Reduced pressure fluctuations when another tap is turned-on
- Reduced water hammer effects - smooth flow
- Reduced operating cost: pump only works as hard as required, when required. Not 100% at all times.
- Quiet pump operations
How does DynaDrive work?
- The speed of the motor is increased or decreased in response to demand
- The more taps that are being used, the faster the motor revs and thus the water flow increases, which in turn keeps the pressure constant and steady
- When the taps are turned off, the motor revs reduce and this also keeps the pressure constant
