Duplex Stainless Steel Benefits

Why Choose Duplex Stainless Steel?

Duplex stainless steel is one of the most superior alloys for use in seawater applications for its versatility and affordability. The combination of austenitic and ferritic stainless steel makes it strong and resistant to corrosion, as well as makes it incredibly durable. Duplex stainless steel is high strength, performative and lightweight – making it an optimal, functional and strong competitor regarding value for your money.

Here at Masterflow, we offer a range of top-quality Duplex Stainless Steel water pumps, including our Duplex Stainless Condenser Water centrifugal pumps. In essence, duplex stainless steel has a lot of benefits that make it a great choice for seawater applications. Let’s take a closer look at why you should use duplex stainless steel in your application.

Strong & Resilient

Although duplex stainless is not as moldable as austenitic stainless steel, it’s still one of the toughest alloys available for seawater applications today. One of the numerous benefits of duplex stainless steel that makes it so favourable is its strength. Resistance to corrosion; like chloride, for example, makes it a secure & hard-wearing choice of seawater pump that will stand the test of time in top condition. Although duplex pumps are useful and suitable for various liquids, they are most commonly utilised for Harbour Water Heat Exchange Condenser Water systems.

At Masterflow, we aim to do our best to make your purchase as convenient and as informed as possible. We provide the complete pump set, including Hot Dip Galvanised (HDG) base plate, electric motor with spacer coupling and stainless coupling guard. Pumps are Back-Pull-Out designs with modular bearing pedestal configurations with common parts across various Models thus optimising interchangeability throughout the range.

High Quality, Lower Price

Is there really anything that makes a purchasing experience better than when you find the right product for the right price? We understand the world can be expensive. We do our best to offer products and services that are of the best value possible for our customers so that you can get the most bang for your buck.

So, if you have been fretting about affordability or worrying about losing quality to meet your budget,  it’s about time to put those fears aside.

Duplex stainless steel contains less nickel and molybdenum (which can drive up expenses), making it much easier on your wallet when compared to some of the pricier alloys on the market. The great news is that it’s cost-friendly without skipping out on quality or endurance.

Duplex stainless steel is a more affordable material than some of its competitors, yet it’s still faster to weld and retains its strength and functionality.

Lightweight

As Duplex Stainless steel is so strong, it is lightweight compared to its resistance or other types of stainless steel.

Environmentally Friendly

Make a positive global impact and reduce your carbon footprint by using duplex stainless steel for your application. Duplex stainless steel has a lower risk of creating pollution, as the manufacturing process is safe. As there is no need for surface treatment, there is no need for chemical interference and decomposition will not release toxins. At Masterflow, we care about the environment and value its protection.  You can read about our policy here.

Convenient

Due to its lightweight, Duplex Stainless Steel is easier and more efficient to move, ship & transport than some of its competitors.
