Trusted RO Plant Spare Parts Supplier in Bangalore (2026)

Available in Bangalore (Same-Day Supply):

Replace every: 3–4 months in Bangalore borewell water; shorter during peak monsoon season.

Activated Carbon Filter Cartridges

Available in Bangalore:

• 10-inch carbon block (coconut shell): ₹150–₹300
• 20-inch carbon block (commercial): ₹280–₹600
• 20-inch jumbo carbon block: ₹450–₹900

Replace every: 6–12 months. Critical for BWSSB supply connections – residual chlorine destroys RO membranes without active carbon protection.

UV Lamps (Germicidal, 254 nm)

Available in Bangalore (Same-Day for Common Configurations):

⚠ Replace every 12 months regardless of apparent lamp condition. UV lamps lose germicidal efficacy before visible light output declines – the indicator light does not tell you whether the lamp is still providing bactericidal doses.

Post-Carbon Polish and Mineralisation Cartridges

• Post-carbon polish (10-inch): ₹150–₹300
• Mineralisation / calcite cartridge: ₹250–₹600
• Replace every: 12 months

RO Membrane Elements – The Most Critical Spare Part

Bangalore Aqua supplies genuine RO membrane elements from verified global manufacturers – with mill test certificates available on request. We do not supply unbranded membranes.

4040 Membrane Elements (4-inch × 40-inch)

Standard configuration for commercial and light-industrial RO plants. The most widely used membrane element format in Bangalore’s commercial water treatment market.

Contact Bangalore Aqua to verify the correct membrane specification for your system before ordering. Membrane selection depends on your source water TDS, operating pressure, and recovery ratio.

8040 Membrane Elements (8-inch × 40-inch)

For industrial plants producing 1,000+ LPH per element. Higher output per membrane housing, better energy efficiency for large industrial systems.

• Available on order from Bangalore Aqua’s procurement network
• Typical supply time: 24–48 hours for Bangalore delivery
• Price range: ₹28,000–₹55,000 per element depending on brand and specification

Membrane replacement signal: Permeate TDS rise > 20% above commissioning baseline; normalised permeate flow decline > 15%; salt rejection below 90%.

High-Pressure Pump Spare Parts

Mechanical Seals (Most Common Pump Failure)

The shaft seal that prevents water leakage at the pump body. Visible symptom: water dripping at the pump shaft during operation.

Important: Always specify your pump brand and model when ordering mechanical seals – seal dimensions and materials vary significantly across models.

Motor Bearings

• Standard centrifugal pump motor bearing set: ₹300–₹1,500
• Deep groove ball bearing (common 6204, 6205, 6206 series for CRI and Grundfos): ₹150–₹600 per bearing

Motor Capacitors (Single-Phase Pumps)

• Start/run capacitor (domestic and light commercial single-phase pumps): ₹150–₹600
• Specification must match motor nameplate – microfarad rating and voltage rating are critical

Impeller Sets and Wear Rings

• CRI India impeller (model-specific): ₹2,000–₈,000
• Wear ring set (CRI India): ₹800–₂,500

For industrial RO spare parts including high-pressure pump components for Grundfos CR series and large industrial pumps, contact Bangalore Aqua’s industrial spare parts team.

Valves and Flow Control

Solenoid Valves

Automatic flow control valves for system start/stop, flush cycles, and level control. Most common failure: coil burnout or valve body scaling.

Critical: Confirm voltage (24V DC or 230V AC), port size (1/4-inch, 3/8-inch, 1/2-inch), and normally-closed (NC) vs normally-open (NO) configuration before ordering.

Multiport Control Valves (Water Softeners and Multimedia Filters)

Injector kit (brine draw component – most common repair): ₹300–₹800 for Fleck series Seal and spacer kit (O-rings for valve body): ₹400–₹1,200

Ball Valves, Float Valves, and Pressure Gauges

• UPVC ball valve (1/2-inch): ₹80–₹200
• UPVC ball valve (1-inch): ₹150–₹350
• Float valve (1/2-inch plastic): ₹150–₹400
• Float valve (1/2-inch brass): ₹300–₹800
• Pressure gauge (0–10 bar, glycerine-filled): ₹200–₹600
• Pressure gauge (0–16 bar, industrial): ₹300–₹800

FRP Pressure Vessel Components

Membrane housing end caps, O-rings, and interconnectors – the consumable components of FRP pressure vessels that require periodic replacement.

Water Treatment Chemicals

Anti-Scalant Chemical

Polymer-based anti-scalant is the continuous-dosing chemical that prevents carbonate scaling on RO membranes in Bangalore’s high-hardness borewell water. Running without anti-scalant accelerates membrane scaling – shortening membrane life from 3–5 years to 12–18 months.

• Polymer-based anti-scalant (suitable for Bangalore’s high-hardness water): ₹500–₁,500 per litre
• Available in 1-litre, 5-litre, and 20-litre containers

CIP (Cleaning In Place) Chemicals

For commercial and industrial systems requiring periodic membrane cleaning:

• Citric acid (food grade, for carbonate scale cleaning): ₹150–₀350 per kg
• Alkaline CIP solution (for organic and biofouling): ₹400–₁,500 per litre

Water Softener Spare Parts

Ion Exchange Resin

Brine Tank Accessories

• Float valve (brine tank level control): ₹200–₆00
• Brine injector kit (Fleck compatible): ₹300–₈00
• Brine tank grid/screen: ₹500–₁,200
• Salt (water softener grade, 25kg bag): ₹400–₈00

Instrumentation and Monitoring

TDS Meters

• Handheld TDS meter (HM Digital or equivalent): ₹200–₈00
• Inline TDS display unit (for commercial panel): ₹500–₂,000
• Replacement probe (for inline TDS display): ₹200–₆00
• Calibration solution (442 standard): ₹150–₀300
