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 13l 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 tank is empty, the rainwater harvesting 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 rainwater harvesting 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 set against dry running, the
system is equipped with a pump control unit in the discharge line. When the pressure
falls below approx. 2.5bar (factory setting) the pump control unit starts up the pump
set. When a consumer installation is closed, the pump control unit will stop the pump
set after an after-run time of 10seconds. A lift check valve prevents the fluid handled
from flowing back. The pressure is indicated by a fitted pressure gauge.
