High Pressure Canned Motor Pumps

Are you looking for efficient, leak-free, and reliable pumps for high-pressure applications? Discover why high-pressure canned motor pumps (CMPs) are the perfect choice for industries requiring durability and minimal maintenance.

What Are High-Pressure Canned Motor Pumps?

High-pressure canned motor pumps (CMPs) are specially designed to handle fluids at pressures as high as 55 MPa, offering superior performance compared to traditional pumps. They are widely used in sectors such as wastewater treatment, supercritical CO2 handling, and seawater desalination. But what makes them the go-to choice for industries operating under extreme conditions? Let’s break it down.

Advantages of High-Pressure Canned Motor Pumps Over Traditional Pumps

When dealing with high-pressure systems, traditional pumps like centrifugal pumps often face seal failures due to high-pressure fluid leakage. These failures result in costly downtime and frequent maintenance.

In contrast, canned motor pumps eliminate the need for mechanical seals by integrating both the motor and pump in a common pressure boundary. This eliminates leakage, reduces maintenance costs, and ensures longer pump life. Key advantages include:

1. Completely Leak-Free Operation:

CMPs provide a completely sealed design, preventing leakage of harmful, corrosive, or flammable liquids, which is critical in industries that prioritize safety and environmental protection.

2. No Contamination:

CMPs don’t allow outside air to enter, making them ideal for vacuum operations or liquids sensitive to atmospheric exposure.

3. Durable and Versatile:

These pumps handle a wide range of pressure and temperature conditions, making them suitable for systems with high-temperature, low-temperature, or high-melting-point fluids. CMPs are also oil-free, reducing contamination risks.

4. Compact and Quiet:

The design is space-efficient and minimizes noise, making CMPs ideal for industries with limited installation space or noise-sensitive environments.

5. Cost-Effective:

The lack of seals, bearings, and couplings means CMPs require less maintenance, translating to lower lifecycle costs and reduced downtime.

Applications of High-Pressure Canned Motor Pumps

CMPs are used in various industries, from environmental water treatment to new energy projects. Here are some examples of successful implementations:

Xiaoqushan BOT Seawater Desalination Project : With pressures reaching 120 bar, Daruihong’s high-pressure pumps were crucial in ensuring efficient, reliable operations.
Waste Oil Refining Plant : After frequent seal failures with centrifugal pumps, the plant switched to a Daruihong canned motor pump. The result? A stable operation for over four years, saving $5,000 per month in maintenance costs.
