Bronze pumps have secured a prominent position in the pump manufacturing industry today. This is primarily due to bronze’s exceptional corrosion and wear resistance, surpassing cast iron’s. Moreover, bronze exhibits a remarkable tolerance to chlorides, making it an excellent choice for various applications involving seawater, power generation, and deep-sea oil and gas.
So why consider a bronze pump?
Let’s explore the advantages of pumps equipped with bronze impellers:
- Low Wear Rate: Bronze impellers experience minimal wear and tear, contributing to the longevity of the pump.
- Operational Capability: These pumps demonstrate reliable and efficient performance, ensuring smooth operation even under demanding conditions.
- Compatibility: Bronze impeller pumps are compatible with water as well as processed liquids such as grease or oil, making them versatile for a wide range of applications.
- Enhanced Axle Stability and Seal Protection: By utilizing bronze, these pumps exhibit improved stability in their axles and reduce wear on the seals, leading to enhanced durability.
- Reduced Axle Wear: Compared to cast iron pumps, bronze impellers are less prone to rust-induced swelling, thereby prolonging the pump’s lifespan.
- High-Pressure Resistance: Bronze impellers possess excellent resistance to high pressure, making them suitable for applications requiring robust performance.
Bronze vs. Cast Iron:
One notable drawback of cast iron pumps, both in terms of their bodies and impellers, is their tendency to seize or “freeze” over time. Conversely, bronze impellers offer superior wear resistance, ensuring a longer-lasting pump while mitigating the swelling issues caused by rust.

Abravan Company specializes in manufacturing various industrial pumps, all of which incorporate bronze materials. If you are interested in purchasing a bronze pump, we encourage you to contact us to place an order. Let’s explore a few examples of our bronze pump offerings:
Bronze Centrifugal Pump:
In the realm of pumps, two main groups exist: centrifugal pumps and positive displacement pumps. Centrifugal pumps are typically preferred for high-flow applications involving liquids with lower viscosity (up to 0.1 cP). In fact, it is not uncommon for chemical plants to employ centrifugal pumps for approximately 90% of their pumping needs.
The efficiency of a centrifugal pump relies on its continuous rotation and high-speed operation. In the case of a bronze impeller pump, its material provides added stability, positively influencing the pump’s performance. However, it is worth noting that these pumps may experience reduced efficiency when handling highly viscous liquids. In such instances, the increased resistance requires higher pressure to maintain the desired flow rate. Centrifugal pumps are most suitable for pumping applications with a viscosity ranging between 0.1 and 200 cP at low pressure but high capacity.

Bronze Hot Oil Pump
The bronze hot oil pump is a centrifugal pump with a single-flow, single-stage helical design. It is available with either a shaft seal or a seal-less magnetically coupled configuration. In this type of pump, the process fluid enters through the suction nozzle and flows into the center of the pump, known as the impeller.
Advantages of the bronze hot oil pump:
- Exceptional Mechanical Strength and Toughness: The pump’s optimal gear arrangement, large central diameter, and optimized angle contribute to its unrivaled mechanical strength and toughness.
- Ample Seal Chamber Volume: The pump features a large seal chamber volume, which allows for effective shaft seal flushing.
- Ductile Iron Body Parts: The body parts of the pump are constructed from ductile iron, ensuring high operational safety.
- Anti-Friction Bearings: The pump is equipped with anti-friction bearings that have a protective disc and are lubricated with grease, resulting in extended operational life.
Choosing the Right Pump:
To purchase the appropriate bronze pump that meets your requirements, consider the following factors:
Fluid Compatibility: Determine the material that needs to be transported through the pump to prevent corrosion and premature wear. Understand the chemical composition of the material, its viscosity, and the possible presence of solid particles.
Understanding Physical Properties: Having a comprehensive understanding of the physical properties of the fluid being pumped allows you to choose an ideal technology that is compatible with the material and meets your needs.
In general, bronze (an alloy of copper and tin) is commonly used for the casing and impeller in electric water pumps due to its excellent combination of resistance to cavitation, cost-effectiveness, wear resistance, and corrosion resistance for various types of water and other fluids.
Buying industrial pumps can be a complex task with several crucial considerations. It is advisable to seek guidance from expert consultants with experience in pump selection. For a convenient purchase, rely on reputable and specialized manufacturers.
