Urgent breakdown: +8801791026660

  • Filter, pump and plant repair

    Something leaking, stopped or giving poor water? Tell us what happened and an engineer will call to find the fault and arrange a visit.

    • Household filters, pumps and industrial plants
    • Fault checked before any part is replaced
    • Parts and charges agreed before the work
    Ask on WhatsApp
  • RO plant installation and commissioning

    Mechanical and electrical installation of the skid, pipe manifolds, the first membrane flush, flow-meter calibration and recovery setting, for plants from 250 to 50,000 LPH.

    • Feed-water TDS, pH and hardness tested first
    • Auto-flush and low/high pressure trips set up
    • Handover with operator training and manual
    Ask on WhatsApp
  • Swimming pool equipment and commissioning

    Circulation pump sizing, filling sand filters with silica or glass media, salt chlorinator setup and underwater LED lighting for hotel, club and residential pools.

    • Head-loss and turnover-rate calculation
    • Pipe pressure test before tiling
    • Water clarity and chemical balance checked at handover
    Ask on WhatsApp
  • Membrane cleaning (CIP) and antiscalant dosing

    Clean-in-place washing to remove organic, silica and calcium-sulphate fouling from 4040 and 8040 membranes and bring permeate flow back up. How much flow returns depends on the membrane's condition.

    • Two-stage acid and alkaline clean
    • Before-and-after normalised flow report
    • Dosing-pump stroke and ppm set for your feed water
    Ask on WhatsApp
  • VFD and pump automation

    Fitting variable-frequency drives and pressure sensors to compatible booster pumps for constant-pressure control. Any energy saving is estimated from your actual duty cycle.

    • PID pressure-loop tuning with 4–20 mA transmitters
    • Star-delta panels converted to inverter drive
    • Dry-run and phase-loss protection
    Ask on WhatsApp
  • Spare parts and maintenance contracts (AMC)

    Replacement pump seals, multiport-valve parts and filter media, plus scheduled maintenance visits. Response time is agreed in the contract and depends on stock.

    • Cartridge mechanical-seal replacement
    • Multiport valve rebuild and rotor service
    • Annual maintenance contracts
    Ask on WhatsApp
  • Lab instrument calibration and water testing

    On-site calibration of pH, TDS, EC, DO and turbidity instruments and routine water tests. Regulatory compliance still needs an accredited lab and the relevant authority.

    • Jar tests to set PAC and polymer dose
    • Multi-point spectrophotometer calibration
    • Buffer solutions topped up
    Ask on WhatsApp

Dispatch time for spare parts is confirmed after checking current stock, destination and courier cut-off. For urgent work, call first to confirm availability.
