- Vacuum and pressure applications
- Fish farming
The Ocean Master 250 is a liquid ring pump in a very strong and compact design. The pump is designed for installation in smaller fish handling systems to transport up to 310 m3 fish per hourMore
For instance, at a 3 meters vertical lift on the suction side the pump can move around 220 m3 of fish per hour.
The waste fish handling lines are also one of the very common applications of Ocean Master 250. Often custom-made, these lines are intended to remove the solid waste (e.g. skin, viscera, fish heads, bones) as well as the liquid waste (e.g. blood water and brine from drained storage tanks) from the fish processing areas. Having a flow up to 310 m3/h, max pressure of 2,0 bar(g) and a max vacuum of 100 mbar abs., Ocean Master 250 is considered the most suitable pump for these relatively small indoor vacuum solutions.More
Ocean Master 250 is equipped with the High Strength Rotor, specially designed by Samson for the fish liquid ring pumps. The High Strength Rotor has been developed based on 40 years’ experience in researching and improving our rotor to withstand the most extreme operations within the fish industry and has proven to be highly reliable for vacuum and pressure operations.
Ocean Master 250 is also considered a replacement pump of Samson KE 225.

For more than 30 years Samson has been the supplier of liquid ring pumps for the fishing industry.
Our very first development for was the Samson HSR rotor, which we designed to withstand the typical but very harsh impacts that occur from pressure operations. The result was a fully welded 100% AISI316 rotor.
Later we learned to improve the lifetime of the surrounding wetted parts, shell and flow plates by using new materials. For that reason we produce almost all Ocean Master 1000 and 700 with shells in AISI 316 and flow plates in bronze.
Our latest development was to implement the a non-corrosive composite liner in the bearing house to prevent corrosion and shortened lifetime.

The suction and discharge performances are calculated in normal cubic meters per hour corresponding to the displacement of water flow in and out of the holding tank. The performance is measured without pressure drop and this must be therefore calculated and added to the static pressure in both suction and discharge. For further information and examples please, refer to the pump manual.

“The introduction of the vacuum system is the biggest positive change that has taken place in the fishing industry in all the years I have been a fisherman,” says Roi Magnussen, chief engineer and co-owner of “H265 Asbjørn”, which is one of Denmark’s largest and most modern fishing vessels.
When “H265 Asbjørn” was built in 2008 – then under the name of “Gitte Henning” – it was Denmark’s largest fishing vessel. Since then even larger fishing vessels have appeared, but “Asbjørn” remains an impressive sight as it lies docked in Hirtshals. At 75.4 meters in length and 15.6 meters at its widest, the well-proportioned ship has a total capacity of 2600 cubic meters of fish, divided into 11 refrigerated tanks.
If you go down into the depths of the fishing vessel you will find four large vacuum pumps from Samson Pumps. A central part of the ship’s giant vacuum system, which is used for unloading the catch, and which plays a crucial role in the efficient operations of an ultra-modern fishing vessel such as “Asbjørn”.
“The introduction of the vacuum system is the biggest and most important change and improvement that has taken place in the fishing industry in all the years I have been a fisherman,” says Roi Magnussen, 49, who is chief engineer on “Asbjørn” and co-owner of the vessel.
