Product catalog summary

Design Features
ESL pumps are single-stage centrifugal pumps designed for high efficiency and low maintenance. They feature a mechanical shaft seal to ensure maximum lifespan and minimal friction loss.

Application Areas

Hot water circulation
Fresh water circulation
Refrigeration
HVAC systems
Hydrophore pump applications
Cooling water systems

The pumps can be equipped with either air-driven or electrically driven priming devices, making them suitable for marine and offshore environments.
