Marine Ballast Water Pump

Introduction of Marine Ballast Water Pump

The Marine Ballast Water Pump is a vital piece of equipment in ship ballasting systems. It performs essential functions such as filling or emptying ballast tanks, balancing the ship's weight and trim, and stabilizing the ship in rough seas. There are different types of Marine Ballast Water Pumps, each with unique features and advantages. Maintaining the pump is crucial to ensuring its optimal performance and compliance with regulations. The Marine Ballast Water Pump offers various benefits, including improved ship stability and safety, increased efficiency, reduced environmental impact, and cost-effective ballasting solutions.

Main Prooducts

Arrangement of ballast pumps

The ballast water system must have 3 or more ballast pumps and its capacity depends on the time required to discharge all ballast water. If the type and size of the ship are different, the total discharge time of ballast water will be different. In general, the ballast water system must fill or empty the largest ballast tank within 2-2.5 hours and the entire ship's ballast tank within 6-8 hours.
The layout of the ballast pipeline system is characterized by the two-way flow of water in the pipe, so the conversion valve box needs to be installed in the ballast system.

Operation of Ballast Water Pumps

1. First close the ballast pump inlet valve, then open the subsea valve, open the ballast pump outlet valve (a global check valve and a glove valve respectively) and the ballast tank inlet valve that requires a ballast pump (if possible Symmetrical opening), outdoor main and side valves.

2. At this time, there is pressure display on the inlet pressure gauge of the ballast pump, please start the ballast pump and pay attention.

Make sure the pressure gauge indicates that the inlet vacuum is between -0.05-0. The outlet pressure is 0-0.4, and the action is normal. When the ballast tank is filled with water, it overflows from the corresponding vent pipe.

After the ballast is complete, close the above valve.
