Faqs

What are bilge pumps used for?

Bilge pumps are used to remove water, oils, and other fluids from the bilge area of a ship, which is the lowest part where unwanted fluids collect. This prevents flooding and maintains the vessel's stability and safety.

What types of pumps are suitable for bilge applications?

Suitable pumps include self priming centrifugal, progressing cavity, diaphragm (AODD), and peristaltic pumps. These are selected based on their ability to handle mixed fluids consisting of oil and water which may contain solids. Due to environmental regulations the bilge water must be fed via an oily water separator prior to discharge overboard to ensure all contaminants are removed. Utilising a low shear pump technology such as peristaltic or progressing cavity can improve the effectiveness of oily water separators.

Which industries use bilge pumps?

The marine industry, including shipping and offshore platforms, use bilge pumps to manage bilge water and prevent environmental contamination.

How do I choose the right bilge pump?

Consider factors such as flow rate, head, space available as quite often a short or compact unit may be the only viable solution, whether the pump needs to comply with any class or ATEX certification and the fluid characteristics. Also note that whilst a positive displacement pump may be a larger investment it will handle fluids of varying viscosity far more effectively, as well as improve the efficiency of any oily water separator (OWS) being used. Consulting North Ridge Pumps ensures expert advice tailored to your specific needs, ensuring optimal pump selection.

Bilge Pumps for Safe and Efficient Waste Management on Ships

Bilge pumps are vital for emptying the bilge tanks, which are located in the lowest part of a ship and serve as the waste run-off collection point. These tanks collect a variety of fluids, including seawater, oils, and chemicals, which may leak from joints, overflows, and pipework. Bilge pumps are responsible for removing this mixture from the tank to ensure the ship’s systems remain operational and free from hazardous waste build-up.

However, bilge pumps cannot discharge this waste directly overboard due to the presence of potentially harmful oils and chemicals. The bilge pump must transfer the contents to an oily water separator, where the fluid is filtered, and a coalescer ensures that the oil content is reduced below a certain PPM (parts per million) before being safely discharged.

Bilge pumps used for this purpose should ideally have dry run protection, especially if they are of the positive displacement type. This ensures that the entire tank is emptied without causing damage to the pump from running dry. Properly specified bilge pumps help maintain safety and compliance with environmental regulations in marine operations.
