          Ocean Master 1500

          Ocean Master 1500 is a liquid ring vacuum pump designed for fish handling in harsh seawater environments with a max capacity of 1500 m3/h.

          Generation 2.0


          Higher performance

          The design of a typical 4-way valve will lead to a significant loss of performance and capacity. Results from tests and comparisons of other 4-way valve brands show that the SAMSON PUMPS 4-way valve will improve the performance of the fish handling system by 20%.


          Designed for tough seawater applications

          The SAMSON PUMPS 4-way valve is casted in duplex stainless steel to withstand the hazardous applications in fish handling. DUPLEX stainless steels are about twice as strong and have a significantly better toughness and ductility as regular austenitic or ferritic stainless steels like EN 1.4401 /AISI316.
