Freshwater is a vital resource that is diminishing in many areas of the world. Reverse osmosis is being used to treat seawater and create a cost-effective water supply for local communities. The cost to the consumers for their water is related to the running costs of the desalination plant. Consequently, optimising efficiency and keeping maintenance costs to a minimum means that plant operators can ensure an affordable water supply.
The new ZF-RO pump is designed to match the technical requirements of energy recovery device booster pump service. It combines the reliable design used in the ZF range, with references for efficiency both in hydrocarbon and desalination industries.
The launch of the ZF-RO pump complements Sulzer’s range of pumps that are designed for operation in the desalination industry. The latest addition is tailored for delivering seawater, or similar liquids, across a wide performance range. For flexible operations, ZF-RO pumps are designed to operate with variable speed drives, enabling them to meet the process specifications as the booster pump for energy recovery devices.
According to Sulzer, the ZF-RO pumps are configured designs to ensure minimal delivery times and extended service life. Improved efficiency has been achieved through hydraulic and mechanical design making a direct contribution to lowering the cost of fresh water to the local population.
The minimal footprint of the pumps makes for a compact installation, maximising the available space within a processing plant.
