Kirloskar CPBS 73624 V 1 HP Pressure Boosting System

The Kirloskar 1 HP Pressure Boosting System is the most popular variant in Kirloskar's HYPN (Hydro-Pneumatic) pressure boosting range, built for independent houses, bungalows, and duplexes with 2 to 3 bathrooms. If you've searched for "pressure booster pump for bungalow" or "water pressure low on upper floor," this is the variant most homes in that category actually need — it's the size point where Indian homebuyers most often land after comparing options, because it balances enough headroom for daily peak usage (morning rush hour when two bathrooms and the kitchen tap are all in use) without the higher running cost of the 1.5 HP model.

The problem it solves: In most independent homes, the overhead tank is the only source of water pressure, relying purely on gravity and height. As soon as more than one outlet is opened — say, a shower running upstairs while the kitchen tap is downstairs — pressure at both points drops noticeably. This is especially common in homes where the tank isn't very high above the highest outlet, or where the plumbing runs long horizontal distances before reaching a tap. The 1 HP HYPN system corrects this by actively pressurising the line itself, rather than depending on tank height alone.

How the HYPN system works: Kirloskar's Hydro-Pneumatic technology pairs the pump with a small pressure vessel (tank). Water is drawn from your existing overhead tank or sump, pressurised, and pushed into your house plumbing at a steady, pre-set pressure. A built-in pressure switch continuously monitors the line: the moment a tap opens anywhere in the house and pressure drops, the pump kicks in automatically — and it switches off on its own once all taps are closed and pressure is restored. There's no manual operation needed, and because the pressure vessel holds a reserve, very short draws (like a quick hand-wash) often don't even need the motor to cycle on, which reduces wear and saves electricity.

Who should buy the 1 HP variant:

• Independent house or duplex with 2–3 bathrooms
• Homes where upper floors get weak pressure
• Overhead tank on ground/first floor feeding multiple points
• Families who need simultaneous shower + kitchen + washing machine flow
• Anyone replacing an old, noisy, or failing booster pump with a more reliable, branded unit

What actual daily use looks like: With a 1 HP system installed, a typical morning where two bathrooms and the kitchen are all drawing water at once should no longer cause a noticeable pressure drop at any single point. The system is built to maintain the outlet pressure the pump was set to deliver, which is a common pain point that leads people to search for "why does my water pressure drop when two taps are open" — this is precisely the scenario a correctly sized 1 HP unit is meant to fix.

Installation considerations: A 1 HP unit is still compact enough to be installed near your existing tank or sump without major civil work in most homes, though the exact placement depends on your plumbing layout — our team can advise on the best location during a site visit. Proper earthing and a dedicated power point are recommended for safe, long-term operation.
