Which Pump is Used in RO?

Introduction: Importance of Pumps in RO Systems

Reverse Osmosis (RO) systems are one of the most reliable technologies for producing clean drinking water. But the system wouldn’t work without a crucial component — the RO pump. Whether you’re installing a new RO purifier at home or sourcing components for commercial use, understanding which pump is used in RO and the Pump RO Price is critical for making the right purchase.

What is an RO Pump?

An RO pump is a device that boosts the water pressure in an RO system to help it operate efficiently. RO membranes require water to pass through at high pressure to effectively remove dissolved salts and impurities. Without a good pump, even the best RO systems won't deliver the desired water quality.

These pumps are most commonly used in homes, businesses, and industrial water purification systems.

Types of RO Pumps Used in Water Purifiers

There are several types of pumps used in RO systems. Let’s take a closer look at the most common ones:

1. Booster Pump

This is the most widely used pump in household RO systems. It enhances the inlet water pressure, which is often low in Indian households. A good booster pump helps your membrane perform at optimum capacity.

Use case: Domestic water purifiers.

2. Delivery Pump

Also known as a pressure pump or transfer pump, this type moves purified water from the RO unit to storage tanks or dispensing taps. It’s more common in commercial or multi-outlet systems.

Use case: Commercial kitchens, offices, hospitals.

3. Permeate Pump

A non-electric, water-powered pump that uses the rejected water pressure to improve recovery rates and reduce wastewater. It increases efficiency without drawing extra electricity.

Use case: Water-saving RO systems.

How Do RO Pumps Work?

RO pumps function by drawing in water at low pressure and delivering it to the RO membrane at higher pressure. Here’s a simple breakdown:

1. The pump pulls water from the inlet line.

2. It uses an electric motor (usually 24V or 36V) to generate higher pressure.

3. The water is then forced through the semi-permeable RO membrane.

4. Clean water is collected, and waste is flushed out.

The more efficient your pump, the better your RO membrane will perform — which means cleaner, tastier water.

Why Booster Pumps Are Critical for RO Performance

Water pressure is the lifeblood of an RO system. If your home has water pressure below 40 PSI (which is common), the system simply won't function properly. Here’s why booster pumps are essential:

• They help achieve the necessary membrane pressure (50–100 PSI).

• Reduce Total Dissolved Solids (TDS) more effectively.

• Minimize water wastage.

• Increase the lifespan of the RO membrane.

• Improve overall system efficiency and flow rate.

If you're serious about water quality, a high-quality booster pump is non-negotiable.

Factors Affecting Pump RO Price

The Pump RO Price can vary greatly depending on several key factors:

1. Brand

Top brands like Flow Life, E-Chen, and Aquagrand are priced higher for their reliability and performance.

2. Voltage and Power Output

24V pumps are standard for domestic RO systems, while commercial setups may require 48V or even 110V pumps, which cost more.

3. Flow Rate

Measured in GPD (Gallons Per Day) or LPH (Liters Per Hour), higher flow pumps are typically more expensive.

4. Construction Quality

Pumps with stainless steel interiors, better rotor materials, and high-grade plastic or aluminum housing tend to cost more.

5. Intended Use

Industrial and commercial pumps are built for durability, continuous usage, and high pressure — hence the price difference compared to domestic pumps.

Domestic vs. Commercial RO Pumps

Here’s a quick comparison between domestic and commercial RO pumps:

Top RO Pump Brands in India

India’s growing water purifier market features many brands. Below are some of the most reliable RO pump brands:

• Flow Life – Known for domestic use and consistent pressure.

• E-Chen – Trusted for both home and commercial models.

• Aquagrand – Affordable and widely available.

• KFlow – Suitable for small commercial setups.

• TDS Care – Ideal for areas with hard water.

• Lexpure – Offers budget options for B2B suppliers.

These brands offer strong customer support, spare parts availability, and compatibility with a wide range of systems.

How to Choose the Right RO Pump

Here are key tips to help you choose the best RO pump for your setup:

1. Check Your Water Pressure

If your home’s inlet pressure is below 40 PSI, a booster pump is essential.

2. Match the Pump with Your RO Membrane

For a 75 GPD membrane, use a 24V pump. For larger membranes (150 GPD+), go with 36V or higher.

3. Choose a Reputable Brand

Don’t just buy the cheapest pump. Opt for brands with warranties and technical support.

4. Voltage Compatibility

Ensure your pump matches your system’s power adapter or SMPS unit.

5. Application Use

If you're using the RO for household purposes, a domestic-grade pump will work. For continuous water demand, go for a commercial pump.
