Features
Extra safetyagainst running dry, with the suction port above pump axis.
ReliableAll hydraulic parts in contact with the pumped liquid are of stainless steel. For liquids from -15 °C to 110 °C.
RobustSingle-piece, thick barrel casing.
CompactSingle-piece lantern bracket and base.Without protruding flange.
Greater protectionagainst leakage, with the pump casing cover separated from the motor shield. Possibility of inspecting the seal through the side apertures between the two walls.Greater protection against water entering the motor from outside provided by anextension of the pump casing around the lantern bracket.

Features
Extra safetyagainst running dry, with the suction port above pump axis.
ReliableAll hydraulic parts in contact with the pumped liquid are of stainless steel. For liquids from -15 °C to 110 °C.
RobustSingle-piece, thick barrel casing.
CompactSingle-piece lantern bracket and base.Without protruding flange.
Greater protectionagainst leakage, with the pump casing cover separated from the motor shield. Possibility of inspecting the seal through the side apertures between the two walls.Greater protection against water entering the motor from outside provided by anextension of the pump casing around the lantern bracket.
