Lagersmit Sealing Solutions
About us
The Liquidyne® pump shaft seals are the alternative to industrial gland packing and mechanical seals. The water-lubricated Liquidyne is the next step towards Industry 4.0 and has a predictable lifetime due to the condition monitoring function. Our industrial sealing solutions are mainly applied to (cooling) water pumps, process pumps, vertical pumps and axial pumps.
Released in 1983, the water-lubricated Liquidyne pump shaft seal was initially intended for heavy-duty dredge pumps. Thanks to its robust design, the seal can handle above-average axial and radial play. It is suitable for pumps that have to deal with severe shocks and vibrations, incorrect alignment and abrasive media. The Liquidyne increases the pump’s lifetime and leads to a longer mean time between maintenance (MTBM) thanks to its robustness. Condition monitoring adds predictability and makes your operation more secure. How? Come and visit our booth (G17) and we will be happy to tell you more about it!
Products
LAGERSMIT - Liquidyne 2-Stage
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 100 microns. The Liquidyne 2-Stage design uses the process medium to lubricate the seal. Benefits: - Predictable lifetime due to condition monitoring - Low power consumption - Maximised maintenance interval - Hard Metal Layer (HML) coating for extra durable grooved liners - No external flush needed - Optional design: the Liquidyne can be designed with divisible housing parts. Ask for more details.
LAGERSMIT - Liquidyne LDS
The Liquidyne LDS design is used in pumps that process polluted and aggressive media. It seals off the pump and uses an external flush to lubricate cool, and clean the seal. The flush flows through the seal as well as towards the pump. This ensures that the pump medium is kept away from the seal to create the most durable solution. The drain flow enables condition monitoring. Benefits: - Suitable for dry start-up - Most durable solution - Predictable lifetime due to condition monitoring - Low power consumption - Maximised maintenance interval - Hard Metal Layer (HML) coating for extra durable grooved liners - No external flush needed - Optional design: the Liquidyne can be designed with divisible housing parts.

LAGERSMIT - Liquidyne 3-Stage (WA)
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 Benefits: - Robust seal design - Dirt retaining module - Predictable lifetime due to condition monitoring - Maximised maintenance interval - Hard Metal Layer (HML) coating for extra durable grooved liners - No external flush needed - Optional design: the Liquidyne can be designed with divisible housing parts.

LAGERSMIT - Liquidyne 3-Stage Vacuum
The Liquidyne 3-Stage Vacuum is specially designed to hold a water column up to eight metres when the pump is at a standstill. The vacuum module also prevents air leakage through the seal into the pump if the pressure inside the pump is lower than the atmospheric pressure, Benefits: - Suitable for dry start-up of the pump - Retains pump medium up to eight metres - Predictable lifetime due to condition monitoring - Low power consumption - Maximised maintenance interval - Hard Metal Layer (HML) coating for extra durable grooved liners - No external flush needed - Optional design: the Liquidyne can be designed with divisible housing parts.
