Bronze Pump Body Processing

Bronze Pump Body Processing

The pump body is the heart of any hydraulic system.bronze pump body processing It has the critical job of supporting the impeller shaft assembly and keeping it true inside the body while maintaining very tight clearances – as low as.003" - the thickness of a human hair! Quality castings and state-of-the-art machining centers are required to meet these extremely demanding tolerances. Bronze pumps are used in many applications where water and other liquids need to be transferred or pumped at high pressure. These include industrial, marine, and domestic applications.

Bronze is a corrosion resistant metal with a natural resistance to biofouling and marine growth.bronze pump body processing These properties make it an ideal material for use in seawater applications such as desalination and pumping fresh water to power generation equipment. It also offers superior cavitation resistance over stainless steel and other corrosive metals.

Historically, aluminum bronze was the standard material of construction for many large vertical seawater pumps because it offered excellent wear and galling resistance, superior corrosion resistance to chlorides, and improved machinability compared to other available alloys at the time of their original construction.bronze pump body processing This material choice has proved itself in the field over time, but there is growing interest in selecting higher strength nickel aluminum bronze to improve corrosion resistance in seawater environments.

Castings from a high-quality foundry will have minimal defects that may interfere with the proper operation of the pump. Depending on the application, the castings may need to be heat treated to optimize corrosion resistance. This is especially important in applications where the pumps are in continuous contact with salt water and corrosive chemicals, such as chlorine.

Bronze-bodied pumps are simple and rugged, and they can be easily serviced. They can also generate a lot of pressure – up to 2 bar (30 psi) – in the short amount of time it takes for them to start flowing (whereas iron and steel-bodied pumps can take minutes).

These self-priming bronze centrifugal pumps are often used for domestic hot water recirculation, sprinkling, circulation, feeding pressurized boilers, and other applications that require high-pressure water. Their compact size and easy installation are also beneficial. They do not require a flange, and they can be connected to 3/4" copper lines with sweat connections.

A bronze cast wear ring is a circular device that fits around the pump's impeller and casing to allow for small running clearance without wearing out the actual impeller or pump casing. These rings are commonly replaced as they wear out, and they can help extend the life of the pump. They are available in a variety of materials, sizes, and configurations to suit different applications, including cast bronze, ductile iron, high-pressure PTFE, or high-strength stainless steel. Choosing the right wear ring for your pump will ensure that it lasts as long as possible and protects the investment in the pump. Using a high-quality cast ring is the best way to minimize the risk of premature wear and failure.
