Lagersmit products

The Liquidyne 2-Stage is the standard design of the Liquidyne range. This seal is used in pumps that process relatively clean media that may contain abrasive particles that are no larger than 100 µm.

The Liquidyne 3-Stage (WA) pump seal is used in pumps that process water containing a relatively large number of abrasive particles or particles larger than 100 microns. Lagersmit developed the Liquidyne 3-Stage (WA), especially for pumps in which the pump water is polluted.

The Liquidyne 3-Stage Vacuum is specially designed for vertical pumps that start up dry. The vacuum allows the pump medium to hold a water column up to eight metres when the pump is at a standstill.

The Liquidyne LDS seals the pump and uses an external flush to lubricate, cool and clean the seal. The water flows through the seal, but also towards the pump side. This water flow also enables the Condition Monitoring function. Do you have a water pump in which the water chamber is dry when you start it up? Is the pressure in the pump lower than the atmospheric pressure? The Liquidyne LDS has been specially designed to cope with these conditions. It also allows for (many) abrasive particles larger than 100 micron flowing through the water.
