Stainless steel pump chains (inox) –
corrosion-resistant and durable

Pump chains are special fully welded chain assemblies used to raise and lower (submersible) pumps normallz located in pumping stations in fresh water and wastewater industry.

They act as a link between the submersible pump and the lifting gear. In order to perform the lifting operation efficiently, the pump chains must be fitted with suspension (master links) links at regular intervals, normall every 1,000 mm. This allows the chain to be secured to an appropriate anchorage point above the shaft and at each stage during the lifting operation.

Two-strand pump chains are also used for larger and heavier pumps or when a change in pump position is required. This variant is constructed in the same way at the top as the single-strand version, but the chain ends at the bottom in two strands, often referred to a a ‘Y’ chain assembly. each of which is connected to the pump. The end fittings can be load hooks with safety device, shackles or suspension links, depending on the requirements of the particular pump.

Like other sling chains, pump chains are manufactured in different grades. A higher grade allows a smaller chain with the same load capacity. Since submersible pumps and thus also the associated pump chains are used in various liquids, high requirements must be met in terms of corrosion resistance and hygiene. For this reason, pump chains are increasingly made of stainless steel, as they offer a longer service life.

Pump chains are used in various areas, especially where submersible pumps are needed to lift and lower loads. One of the main areas where pump chains are used is in the fresh water and wastewater industry: in sewage treatment plants, wastewater systems and water treatment plants, pump chains are used to move submersible pumps in wells and to pump water or wastewater.

Their use depends on the specific requirements and conditions of the particular application. As submersible pumps are a reliable and efficient method of lifting and lowering liquids, pump chains are of great importance in many industries.

Pumping maintenance is critical to operating an efficient wastewater treatment plant. Failure of the pumps can result in waste spillage into the water course and rivers or into the household. Preventing this happening is very important and protects the environment. Reliable chain system is critical to enable the pumps continue to run with limited down time.

Stainless steel pump chains have many advantages:

1. Corrosion resistance: high quality stainless steel is known for its excellent corrosion resistance. This means that these pump chains will not rust or corrode when used in the harshest environments.
2. Durability: due to their robust construction and high-quality, stainless steel pump chains can perform at high levels over long periods of time without breaking or wearing out.
3. Heat resistance: stainless steel can withstand high temperatures,
4. Hygiene: stainless steel is easy to clean and sterilise, making these pump chains ideal for applications in the food industry, hospitals and wherever cleanliness is important.
5. Reduced maintenance: because they do not rust or corrode, stainless steel pump chains require relatively little maintenance. This can lead to long-term cost savings.
6. Environmental friendliness: compared to other materials, stainless steel is easier to recycle and therefore more environmentally friendly.
