This latest case study explores the supply of two self-priming seawater extraction pumps for a new whisky distillery.

The pumps were required to draw seawater through a 65m suction pipe from 4.2m above sea level before transferring it 1.4km inland, providing a reliable cooling water supply for the distillery’s production process.

The Challenges of Seawater Extraction
While highly effective, seawater extraction presents several engineering challenges. Systems must be designed to cope with fluctuating tidal levels, abrasive sand and silt, marine growth, and the risk of debris entering the intake. Long suction distances and variable cooling demands add further complexity, requiring careful hydraulic design to maintain reliable priming and prevent issues such as cavitation.

What was our specification for this client?
As the UK’s largest pump maker with over a quarter of a century in business, we have a wealth of specialist knowledge and in-depth experience.

We use our knowledge to develop the right pump solution for every client. What’s more, we can specify any pumps available on the market, not just one pump type or technology.

For every client, we select the best pump for every project offering the optimum mix of price, performance and specification.

Self-Priming Distillery Cooling Pumps
The distillery required self-priming seawater extraction pumps capable of handling challenging operating conditions. Installed 4.2m above sea level, they draw seawater through a 65m suction pipe before pumping it 1.4km inland, while coping with fluctuating tidal levels.

We supplied two XCP end-suction pumps, manufactured from duplex stainless steel with a C5 marine coating for superior corrosion resistance. Each pump delivers approximately 120m³ of seawater per hour.

Designed for reliable, continuous operation, the pumps feature an oil-lubricated bearing housing and additional pump-head bearings to reduce motor strain, making them ideal for demanding marine and industrial applications.

In addition, the long-coupled design maximises durability and makes maintenance easy, as the pump head can be accessed without taking out the motor.
