Rubber Vs Metal: Which Parts are Better for Slurry Pumps?

Rubber Vs Metal: Which Parts are Better for Slurry Pumps?

When it comes to slurry pumps, the material used for their important components is a crucial decision. Typically, two options are available for slurry pump parts: rubber and metal. But which one is better? Let's take a closer look.

Rubber components.

Rubber parts are a great option if pumping slurries with abrasive or corrosive properties. The rubber lining acts as a protective layer that can absorb the impact of solid particles. This means longer life for the pump’s parts. .

Advantages of rubber components.

Firstly, rubber parts are much more cost-effective than their metal counterparts. Additionally, rubber parts reduce the impact of noise and vibration for slurry pumps. Above all, rubber parts provide better corrosion and abrasion resistance.

Drawbacks of rubber components.

Rubber parts are subject to wear and tear faster than metal parts. While rubber parts are relatively resistant to the impact, they may not be able to withstand high-pressure applications.

Metal components.

Metal components are ideal for pumps that handle non-abrasive slurries. For applications involving high-pressure, metal components are the preferred choice because rubber components may not withstand the excessive pressure.

Advantages of metal components.

The primary advantage of metal parts is their strength and ability to withstand pressure and wear and tear. Moreover, metal parts tend to have better heat resistance than their rubber counterparts. .

Drawbacks of metal components.

The downsides of metal parts are that they can be noisy and produce vibrations when compared to rubber parts. In the case of highly corrosive slurries such as acid, a metal component may begin to corrode over time and lose its function.

Which is best?

Deciding which of these materials is better for slurry pump parts depends largely on the nature of the application. While rubber lining is preferred in applications that require resistance to corrosion and abrasiveness, metal components are better for high-pressure applications.

Final thoughts.

It is evident that both metal and rubber have advantages and disadvantages in slurry pump component construction.
