সম্পূর্ণ বোরওয়েল পাম্প ইনস্টলেশন গাইড

Before lowering the pump:

• Verify pump model matches borewell diameter and HP requirement
• Check borewell yield with test pumping if new
• Confirm cable size for depth and HP (dealer chart)
• Arrange GI/HDPE delivery pipe, NRV, foot valve if needed
• Ensure control panel with overload, dry-run protection and proper earthing

Use flat submersible cable of correct sq mm for motor HP and installation depth. Poor cable causes voltage drop and motor failure.

• Joint cables only with approved waterproof couplers
• Never splice cable mid-borewell with tape alone
• Support cable separately from pipe weight using clamping at intervals
• Leave service loop at top for future maintenance

• Use recommended pipe diameter for pump discharge
• Install NRV above pump to prevent backflow and impeller damage
• Tighten fittings to prevent air entry
• Align pipe centrally — avoid pump body touching borewell walls
• Lower pump and pipe slowly with sturdy mounting chain or rope on rated hook

• Attach pump to pipe at borewell head
• Lower section by section, coupling pipe as you go
• Maintain minimum submergence below water level at all times
• Set final depth per dealer recommendation (above borewell bottom)
• Secure top assembly on sturdy borewell head plate

Never drop the pump — impact damages impeller and seals.

Connect to control panel with:

• MCB and overload relay matched to motor FLA
• Dry run protector or water level sensor
• Proper earthing to prevent shock and surges
• Stabilizer if voltage fluctuates beyond ±10%

Three phase: verify correct rotation direction. Single phase: use recommended starter type for HP rating.

First start procedure:

• Fill delivery line if required
• Check voltage at panel under load
• Run pump for 15–30 minutes and observe amperage
• Verify discharge at outlet — no air or vibration
• Register warranty with dealer after successful commissioning

কিংগওয়েল pumps are factory load tested before dispatch.

• Clean strainer every 3–6 months
• Inspect cable joints annually
• Never run dry — monitor water level seasonally
• Schedule dealer service yearly
• Keep installation record and invoice for warranty claims

Professional installation through authorized কিংগওয়েল dealers is recommended for warranty coverage.
