Delta – ZERO
The system uses the energy generated by a water pump with water pump efficiencies, which transfers the energy through a wear-resistant flexible membrane within a pressure vessel to the driven media. At all times, the pressures on either side of the membrane are balanced, hence the name Delta-Zero®.
A maximum of 800m3/hr is obtained by a single unit and only require a maximum of six days per year for maintenance (giving a maintenance availability of 98.5%). Each system is designed for an operational life of 20 years at 100% of the design efficiency, therefore reducing replacement costs of normal pumping systems which are typically replaced every 5 to 6 years of operation
