Products Description
High Pressure Pumps For Desalination is a pump specifically designed for the desalination process, designed to transport seawater from the ocean or other water sources to the desalination unit and provide the necessary pressure to achieve the desalination process. They play a vital role in modern freshwater supply, especially in areas where freshwater resources are scarce or severely in short supply. Due to the high corrosiveness of seawater, desalination pumps are usually mad.
application
- Desalination - Reverse Osmosis Desalination
- Brine Concentration - Zero Discharge
- Boiler Feed Water
- Cleaning Pump Stations
- Any other high pressure application for clean liquids
feature
- high Pressure Pumps For Desalination casing - adopts segmented radial split structure, larger inlet and outlet sizes, optimized inlet flow, low noise level, higher allowable nozzle force and torque; radial fully symmetrical hydraulic design to minimize radial force, improve overall efficiency and extend the effective life of the rotor and other components.
- Flange - According to the customer's piping requirements, the inlet and outlet flanges can be set on the side or top, including the typical same-side inlet and outlet configuration
- Middle section and guide vane - integrated design and manufacturing, greatly reducing the matching surface to improve matching accuracy, improve operation stability and extend life
- Impeller - excellent hydraulics, high efficiency and energy saving
- Main shaft - heavy-duty main shaft, the shaft offset is minimal under the maximum heavy load to ensure the good operation of the running parts on the shaft, more stable pump operation, longer life of bearings and mechanical seals, and reduced maintenance and repair costs
- Larger bearing chamber, thin oil lubrication, grease lubrication can also be selected
- Axial force balance - balance drum is used to balance the axial force
- Shaft seal - mechanical seal, packing can be selected for special applications
- Parts - modular design, high degree of generalization, reducing spare parts inventory.
Our Advantage
Low overall cost:
The performance of raw materials and bearing components is improved, and a high speed (2P) design is adopted, which reduces the size of the pump and increases the strength of the rotor components. Under the premise of ensuring reliability, users can build and maintain at low cost.
Multi-industry application
Operation:
Optional vibration and temperature alarms can predict the life of the equipment and avoid abnormal shutdown
Maintenance:
Configured with magnetic labyrinth oil seal, non-contact with the shaft, no wear on the shaft, and reduced oil leakage probability;
Configured with bearing sleeves, which facilitates the maintenance of the shaft seal to avoid damage to the bearing.
High efficiency and energy saving:
High Pressure Pumps For Desalination has Higher efficiency, lower operating and maintenance costs

FAQ
Q: What material grades does Mislier offer for high-pressure seawater pumps to prevent corrosion?
A: We provide tailored metallurgy based on the raw water's TDS (Total Dissolved Solids) and chloride concentration to eliminate pittings and crevice corrosion:
Stainless Steel 316/316L (SS316): Ideal for Brackish Water Reverse Osmosis (BWRO) with TDS less than 10,000 ppm.
Duplex Stainless Steel 2205 (S32205): The standard choice for Sea Water Reverse Osmosis (SWRO) with TDS up to 40,000 ppm.
Super Duplex Stainless Steel 2507 (S37250): Engineered for harsh high-salinity environments (e.g., the Gulf region) with TDS greater than 40,000 ppm.
Q: Can Mislier high-pressure pumps directly replace major European or American brands in existing RO systems?
A: Yes. Our high-pressure pumps are designed with standard international dimensions (including ISO/ANSI flange configurations and shaft centerlines). They can serve as cost-effective drop-in replacements for prominent global brands (such as Grundfos CR/CRN series, Danfoss APP, Fedco, or Sulzer). We can match your exact flow, head, and duty point to minimize piping modification costs during system retrofits.
Q: How does Mislier ensure the reliability of these pumps under 24/7 continuous industrial operation?
A: Down-time in a desalination plant is extremely costly. To ensure 24/7 reliability, our pumps are upgraded with:
Axial Thrust Balancing Drum: Significantly neutralizes heavy hydraulic backpressures, extending the bearing lifespan.
Heavy-Duty Bearing House: Optimized with optional oil-bath lubrication to prevent overheating during uninterrupted heavy-duty operations.
Cartridge Mechanical Seal: Allows quick replacement without dismantling the motor, slashing maintenance time from hours to minutes.
Q: What quality control tracking and material certificates do you provide for project bidding?
A: We fully support engineering contractors (EPCs) with comprehensive documentation required for industrial bidding. Every shipment can be accompanied by:
EN 10204 3.1 Material Certificates (verifying the chemical composition and mechanical properties of our Duplex/Super Duplex steel).
Hydrostatic Pressure Test Reports (conducted at 1.5 times the maximum working pressure to ensure zero leakage).
Factory Performance Testing Curves (verifying Flow, Head, Power, and Efficiency at our advanced testing facility before dispatch).
Q: Can you customize the motor specifications for global projects?
A: Yes, we offer complete motor flexibility to match local grid requirements worldwide. We can equip our pumps with three-phase premium efficiency motors (IE3/IE4) supporting 50Hz or 60Hz frequencies, and voltages ranging from 220V, 380V, 440V to 460V, with IP55/IP56 protection and Class F insulation.
