Areas of application
The pumps will be used to deliver clean water out of wells, creeks and tanks for irrigation, domestic water supply, etc. The pumps are
designed for pumping thin, clean, non-explosive liquids, not containing solid particles or fibres. The temperature of the pump liquid must not
exceed 40°C.
Sand and other abrasive parts may damage the seals or other parts of the pump (use a pre-filter).
