Davey DD90-11 Variable Speed Pressure System (Flow 130 LPM)

The Davey HM Water Pressure System range with Variable Speed Drive controller is a premium product designed for multi-storey buildings and homes with high pressure needs. The VFD controller allows the pump to only turn on as much power as demanded by the system, saving you power and extending the life of your pump. The Dynadrive pump can be coupled with additional Dynadrive pumps to provide redundancy as well as increased flow rate at fixed pressure.

DynaDrive is our latest all-in-one home pressure system to solve water pressure issues. As a constant pressure pump, the 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’s constant pressure, you can keep pressure constant and steady. As taps are turned off, the drive adjusts automatically, keeping the pressure constant while saving energy.

With DynaDrive you can expect:

• Consistent pressure when another tap is turned on
• Smooth and quiet flow
• Reduction in water hammer
• Reduced operating costs
• Quiet pump operation

DynaDrive features an integrated controller that is easy to set up and use. It allows you to set your desired water pressure while also being energy efficient. By reducing the pressure on your system when it’s not needed, DynaDrive reduces the energy consumed, saving you money.

DynaDrive has been certified and tested to comply with the requirements of the AS/NZS 4020 standard. The AS/NZS 4020 standard stipulates that products in contact with drinking water do not affect the taste or appearance of the water, do not support the growth of micro-organisms and do not release cytotoxic or mutagenic compounds or metals into the water.
