Spiral pump for Salmon roe

The spiral pump is based on an ancient law which states that each object, once in the water,loses weight proportionally to the amount of water it displaces. The material is mixed with sea, liquid brine or fresh water so it gains its "original" weight. The material is therefore less likely to get damaged during transport. The spiral pump is  “non propeller” as it revolves the whole drum inside.The spiral pump can pump salmon roe mixed in full salinity brine. This setup ensures accurate timing and control of the brining/hardening process. (How long roe is in the brine). The spiral pump is made of high quality AISI316 Stainless steel. The pump has a variable el.speed control and is easy to install and operate.
