A failed antiscalant dosing pump means membrane scaling begins within hours. A pre-treatment pump failure raises SDI and damages the membrane train. Alisios sources genuine Grundfos parts through authorized distributors and responds in 4 hours.

Grundfos pumps appear at every stage of SWRO — seawater intake lift, media filter backwash, cartridge filter feed, antiscalant dosing, biocide dosing, high-pressure booster and product water distribution. Each one is critical. Antiscalant dosing pump failure in Gulf seawater, where scaling indices are extremely high, begins causing carbonate and sulphate scaling on membrane elements within 4–8 hours. Biocide dosing failure triggers biofouling that can permanently damage the membrane train within 24–72 hours and is not fully reversible by chemical cleaning.
On Maldivian resort islands and remote Gulf desalination stations, there is no nearby distributor. The Grundfos CR or CME pump that has just failed is the only one in the system. Alisios sources replacement parts and exchange units through authorized Grundfos distributors in UAE, India and Europe and responds within 4 hours.
Grundfos pump type code from the nameplate (e.g. CR 32-3-2 A-F-A-E-HQQE or CME 5-7 A-S-G-E-W-AQQE), serial number, specific part required or description of failure, quantity, destination and whether the plant is currently down. The type code contains the full configuration including materials and seal type — it is essential for ordering the correct parts.
CR/CRI/CRN vertical multistage, NK/NKE/NB end-suction, CME/CM horizontal multistage, SP submersibles and DME/DDE dosing pumps. Submit your Grundfos type code from the nameplate for a 4-hour response.
Extremely urgent. Antiscalant dosing failure in Gulf seawater can begin causing irreversible membrane scaling within 4–8 hours due to the high scaling potential of Gulf seawater. Biocide dosing failure triggers biofouling that may permanently damage the membrane train within 24–72 hours. Alisios treats these as near-AOG events and responds accordingly.
Yes. CR and CME series pumps are widely used in Maldivian resort and island desalination systems, including remote outer islands. Alisios sources through authorized Grundfos distributors and arranges air freight to Velana International Airport or Male, with onward transfer to resort islands.
Authorized distributor certificate confirming genuine OEM origin. EU Genuine Track orders additionally include chain-of-custody documentation and Spanish customs export declaration. All parts are genuine Grundfos OEM — no aftermarket substitutes.
The type code on the pump nameplate encodes the full pump configuration — series, size, number of stages, materials and seal type. For example CR 32-3-2 A-F-A-E-HQQE identifies a CR series pump with HQQE mechanical seal for seawater service. Without the type code it is impossible to confirm the correct seal material for saltwater contact. Always include it in your RFQ.
Yes. For plant-down situations where sourcing individual parts would take too long, Alisios sources complete Grundfos CR and CME exchange pump assemblies through our authorized distributor network. Submit pump type code, serial number and destination to sourcing@alisios.co or WhatsApp +34655099909.
