Lowara DOC 3 Submersible Pumps

Free Delivery2 Year GuaranteeBest Price GuaranteeFree Expert Advice

Lowara DOC pumps are versatile, corrosion-resistant and compact - Ideal for draining wells, garages, cellars or places subject to flooding, septic tanks and powering garden fountains. There versatility means they can be used in fixed or mobile installations. Available with or without float switch for automatic operation. 

To ensure long life, the motor has thermal overload protection and a triple seal system to prevent water entering the motor. The stainless steel rotating shaft is also protected by a double labyrinth, V-Ring and impeller counter blade, which prevents solids and fibrous material damaging the shaft seals. 

Whisper Pumps supply a special artificial head valve, which considerably reduces electricity consumption and extends the life of the pump. The spring loaded valve regulates the flow of the pump so that it operates at the point of maximum efficiency (see chart). This reduces electricity consumption by up to 50% and allows the motor to run much cooler.

GT versions have a compact tubular float switch, allowing the DOC pump to be used where standard float design can-not work due to insufficient space. These versions can only be used with clean water and installed vertically.
