3 High-pressure pump 7 Mains water supply

tank
Design A multi-stage self-priming high-pressure pump (3) is installed in an angled tank (2)
designed for wall mounting. Via a three-way valve (4) the high-pressure pump is
connected to a suction nozzle (5) leading out of the system for connection to a
rainwater storage tank.
Function The high-pressure pump (3) withdraws fluid handled from the rainwater storage tank
via the suction nozzle (5). A second suction nozzle (8) leads to an integrated mains
water storage tank, which contains approximately 13l of water. The water in the
mains water storage tank is automatically replenished with drinking water and/or
service water via a float valve. If the sensor fitted in the rainwater storage tank
indicates that the rainwater storage tank is empty, the system will automatically
switch to the mains water storage tank via a three-way valve (4). It will withdraw
water from the mains water storage tank until the rainwater storage tank contains a
sufficient amount of water again. Once the rainwater storage tank contains enough
water again, this condition is signalled to the system, which will then automatically
switch back to withdrawing water from the rainwater storage tank. The pump set is
started and stopped when a consumer installation is opened and closed.
Monitoring equipment For monitoring purposes and for protecting the pump against dry running, the
system is equipped with a pump control unit in the discharge line. When the pressure
falls below approx. 2.5bar (factory setting) the pump control unit starts up the pump
set. When the consumer installation is closed again, the pump control unit stops the
pump set after an after-run time of approx. 10seconds. A lift check valve prevents
the fluid handled from flowing back. The pressure is indicated by a fitted pressure
gauge.
