Water pump

An underground monolithic water tank equipped with a submersible pump is an ideal solution for using rainwater for garden irrigation. The tank has a built-in automatic sensor for starting and stopping the pump. An automatic integrated sensor protects the pump against running dry in case of lack of water. The high-quality pump is made of stainless steel + plastic. The pump has a 1" suction opening, to which a 1 m hose with a return strainer is connected, which prevents the suction of dirt from the bottom of the tank and thus protects the pump from clogging.

Basic parameters of the pump:
  • Flow rate: 105 lt/min.
  • Power supply: 230 V
  • Connecting cables: 15 m
  • Power/current: 1200 W / 5.2 A
  • Pump displacement: 44 m
