SPECTRA WATERMAKERS Clark Pump’s core technology reduces energy consumption by 75% compared to traditional systems
our technology
A water generator or desalinator is a device that produces potable water from seawater or salt water through reverse osmosis. The reverse osmosis process typically requires a large amount of energy, so we use energy recovery pressure amplifiers to enable your water making machine to run from solar panels, wind turbines or battery banks. This pump can reduce energy consumption by up to 75%, significantly improving energy efficiency compared to traditional systems.
This technology not only saves energy, but also makes outdoor adventures more sustainable, allowing users to have a stable source of clean water whether they are sailing at sea, hiking and camping, or exploring remote areas. We are committed to providing efficient, environmentally friendly water treatment solutions to ensure your outdoor life is more comfortable and safer.
Traditional water making machine
In a traditional water maker, a high-pressure pump, similar to a high-pressure cleaner, increases the pressure of the incoming raw water to 800-1000 PSI (55-69 Bar). These large pumps use powerful force to push seawater against a back-pressure valve to create the required high pressure. However, only a small portion of the water that passes through the water generator can pass through the reverse osmosis membrane and be converted into fresh drinking water. This means that a lot of energy is wasted in raising the entire volume of raw water to such a high pressure.
This traditional method is inefficient and not only consumes a lot of energy, but also increases the operating cost and maintenance frequency of the equipment. In contrast, our technology significantly reduces energy consumption and improves overall efficiency through energy recovery pressure amplifiers, making water treatment in outdoor activities more economical and environmentally friendly.
Energy recovery water making machine
When seawater passes through the reverse osmosis membrane of the water generator, it still maintains a pressure of up to 1000 PSI (69 Bar). The energy recovery device diverts energy typically wasted in conventional systems away from the outlet and to the incoming raw water, significantly reducing the power required to operate the system. All Spectra water makers use similar energy recovery technology that directs a high-pressure waste stream to the bottom of the pump piston, allowing them to recover 90% or more of available energy.
All Spectra water generators automatically adjust (as part of the hydraulic design) to changes in water temperature and salinity, so no adjustments are required for use in different climates, bays, rivers or oceans. This allows our systems to operate efficiently in a variety of environments, providing a stable and high-quality source of drinking water. This technology not only improves energy efficiency but also reduces operational complexity, making outdoor adventures more convenient and reliable.
Clark Pump
In 1997, Spectra took the lead in launching a new and efficient water generator energy recovery device - Clark Pump. The Clark Pump is a hydraulic booster and energy recovery device that uses a low pressure feed pump (as low as 60 PSI or 4.1 Bar in some systems) to provide sufficient pressure for reverse osmosis. Clark Pump recycles the energy in the pressurized water flow to increase the low-pressure water supply to 800 PSI (55 Bar), thereby reducing energy consumption by up to 75%, greatly improving efficiency compared to traditional systems.
The Clark Pump is constructed from modern composite materials and engineered plastics to provide years of quiet, reliable service. This technology not only improves the energy efficiency of water generators, but also reduces operating costs and maintenance requirements, making water treatment in outdoor activities more sustainable and cost-effective. This innovative technology from Spectra allows users to easily obtain a stable source of drinking water no matter what the environment.
Pearson Pump
It is a unique piston-driven reverse osmosis pump with built-in energy recovery technology. This unique technology allows the system to operate with only 25% of the power of traditional systems and is quieter than other similar systems. Pearson Pump's soft start technology ensures there are no current surges, protecting equipment and power systems.
The Pearson Pump is constructed from engineered composites and superduplex stainless steel for superior corrosion resistance and long service life. These high-performance materials ensure that the pump can operate stably in various harsh environments and provide reliable fresh water supply. The Pearson Pump's innovative design and high-efficiency technology make it an ideal choice for users seeking energy efficiency and long-term reliability, whether they are sailing, camping or other outdoor activities.
