TWIN JOLLY 25 is a kit composed by two automatic pumps assembled in series and fitted on a single wall bracket.

TWIN JOLLY 25 provides the following functions completely independently: starting, stopping and dry run protection, in gravity fed systems with header tank or in pressure system, including centralised condominium supplies.

The water-cooled motor assures silent running of the pump so it can be installed easily anywhere in the home or in a roof space.

Features

  • power supply: 230 V C.A. 50 Hz

  • motor load: 2 x 245 W

  • IP: 20

  • h max: 2,5 bar

  • flow max: 20 l/m

  • water temperature: max 60 °C

Description

  • operation of JOLLY PUMP 25 is extremely straightforward:

    • when a shower tap is turned on, as soon as the water flow in the pipe exceedes 3 l/min it is diverted by the unit’s internal flow control valve, causing the motor start

    • the resulting increased flow is supplied constantly until the tap is turned on

    • when a tap is turned off, the interruption of the water flow causes the motor to stop immediately

  • this prevents potentially harmful pressure rises in the water circuit

  • the same principle assures dry run protection of the pump which stops immediately in the absence of water
