Overview: The Lowara DOC Series consists of submersible pumps designed for both clean and dirty water applications. These pumps are corrosion-resistant, compact, and available in three versions with either channel or Vortex impellers. They can be supplied with or without a float switch and feature a built-in capacitor. The motor is cooled by the pumped liquid and includes thermal overload protection.

Materials: The pump body, suction screen, handle, upper support, and impeller are made of Noryl®. The outer sleeve, motor casing, lower cover, screws, tie-rods, and shaft extension are made of stainless steel. Elastomers are made of NBR.

Applications: These pumps are suitable for emptying residential sump pits, rainwater tanks, garden and lawn irrigation, emptying tanks or reservoirs, and emergency draining of flooded areas. A shallow suction device is available on request for complete drainage up to 3 mm from the floor.

Hydraulic Performance: The performance table provides flow rates and head values for different pump types at 50 Hz. For example, the DOC3 delivers up to 6.9 m at 0 l/min, while the DOC7VX delivers up to 7.2 m at 0 l/min.

Electrical Data: The pumps operate on single-phase 220-240 V or three-phase 220-240 V/380-415 V. Capacitor values and current ratings are specified for each model.
