TWIN JOLLY PUMP 25 automatic pump
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.

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
