Sea Water Pump

Kingda seawater pumps can reliably pump seawater, and even water containing chemicals, for extended periods under extremely harsh conditions. This is thanks to their superior materials, which resist corrosion from chlorides in seawater and abrasion from hard particles, ensuring a long service life.

Sea Water Pump Definition

Sea water pumps are specifically designed for conveying seawater, salt water, or corrosive liquids. They are commonly used in ship cooling water systems, seawater desalination, seabed sand mining, and seawater circulation.

To avoid corrosion and abrasion from seawater, sea water pumps are typically made of special materials, such as duplex stainless steel, bronze, alloys, and composite materials, to withstand the corrosive and abrasive properties of seawater and ensure durability in high-salt, high-solids environments.

Sea water pumps generally employ a centrifugal structure. When selecting a pump, the material should be chosen based on the medium being conveyed to ensure durability and achieve optimal service life.

Sea-Water-Pump-Definition

Kingda sea water pumps offer a variety of material options, including stainless steel, bronze, alloys, and composite materials. These superior materials easily withstand the corrosion of chlorides in seawater, ensuring long-term seawater transport.

Seawater contains a large number of solid particles, including sand, gravel, and fibers. These substances generate intense friction on the pump during high-speed transport, leading to erosion.

The Kingda sea water pump can easily withstand the high-speed scouring of solid particles in seawater, maximizing its service life.

Kingda Sea Water Pump Function

Seawater pumps are commonly used for pumping seawater, including drawing seawater from the ocean and transporting it to target areas, circulating seawater on offshore platforms, transporting seawater containing solids, pressurizing seawater, and discharging wastewater.

Pump Sea Water: The primary use of a seawater pump is to pump seawater. For example, in a seawater pumping system, it is used to draw chloride-rich seawater from the ocean and pump it to a designated area.

Seawater Circulation: Continuous seawater circulation is required in the cooling systems of some offshore platforms, aquaculture systems, or ships to ensure stable temperature and water quality.

Pumping Seawater Containing Solids: Seawater often contains sand, gravel, stones, long fibers, and even debris. Ordinary water pumps struggle to handle these solids, often leading to blockages. Seawater pumps, however, can easily handle solids and possess excellent abrasion resistance.

Seawater Pressurization: Seawater lift pumps can provide sufficient pressure for offshore platforms or water supply systems, enabling the transport of seawater to structures or equipment tens of meters high.

Sea Water Pump Material​

The choice of materials for a sea water pump is a crucial factor affecting its reliability and lifespan. Only by selecting suitable materials can the pump’s stability during operation be guaranteed.

Stainless Steel

The biggest characteristic of stainless steel is its resistance to rust and corrosion, and it exhibits excellent stability in oxidizing media.

Stainless steel sea water pumps can maintain excellent stability when conveying chemically corrosive substances of varying temperatures and concentrations.

Bronze

Bronze is a commonly used material for sea water pumps. It is more corrosion-resistant than ordinary steel and easier to process, making it suitable for most seawater applications.

However, its abrasion resistance is not as good as wear-resistant alloys.

Wear-resistant alloys

Wear-resistant alloys are particularly suitable for seawater containing a large amount of solid particles, such as gravel, mud, and long fibers. In these situations, choosing wear-resistant alloy materials is the best option.

Wear-resistant alloys not only resist chemical corrosion but also have high abrasion resistance.

Seawater contains a large amount of corrosive substances. We must not only ensure the seawater pump is sufficiently corrosion-resistant, but also withstand the high-speed impact of gravel in the seawater. These hard solid particles in seawater can severely abrade the metal surface, significantly shortening its service life.

Kingda has developed a variety of corrosion-resistant and abrasion-resistant materials tailored to the different physical properties of seawater. Verified through numerous projects, this effectively extends the pump’s service life, enabling long-term operation and minimizing maintenance frequency, thus solving the problem of inconvenient maintenance when used at sea or on ships.

Why Choose Kingda Sea Water Pumps

Common Problems with Ordinary Sea Water Pumps

Short service life

While the materials used in ordinary sea water pumps can resist corrosion, they are ill-suited for abrasion-resistant applications. During pumping, the high-speed flow of solids continuously erodes the metal, causing severe wear and significantly reducing its lifespan.

Frequent clogging

Commonly available sea water pumps have small inlet diameters and low efficiency. Large solid particles or long fibers can easily clog the inlet or impeller, leading to downtime for maintenance and significantly increasing operating costs.

Prone to leakage

Ineffective sealing devices have extremely short lifespans and are unable to withstand long-term chloride corrosion and suspended particle erosion, causing seal cracks, liquid leaks, and damage to the sea water pump.

age to the sea water pump.

Frequent clogging and leakage problems in ordinary sea water pumps mean that a significant amount of time and manpower is required for maintenance, impacting project progress and increasing costs considerably.
