GENERAL DATA<br />
These are UNI 9490-10779 compliant pressurisation units for delivering water to fire-fighting systems.<br />
The standard version comprises:<br />
- one or two K 55/50 k 55/100 electric pumps twin impeller.<br />
- one or two KV 6/7 KV 10/8 centrifugal multistage electric pumps on a vertical axis.<br />
There is no version with a compensation pilot pump.<br />
Constructional characteristics<br />
BASE<br />
Galvanised steelbase supporting the electric pump/s, pilot pump and electrical panels.<br />
ELECTRIC PUMPS<br />
K 55/50 K 55/100 single-piece centrifugal electric pumps twin impeller.<br />
Cast iron pump body, impeller in technopolymer, carbon/ceramic mechanical seal.<br />
Asynchronous, closed 2-pole motor, cooled by external ventilation.<br />
KV 6/7 KV 10/8 centrifugal multistage electric pump on a vertical axis.<br />
Discharge and suction body in cast iron, impeller and diffuser intechnopolymer.<br />
Asynchronous, closed 2-pole motor, cooled by external ventilation.<br />
HYDRAULIC PART<br />
Separate suction lines for each pump, complete with vacuum pressure gauge.<br />
Delivery of each main pump to the manifold with connections for suction tanks, pressure gauge, pump running pressure<br />
switch, inspectable check valve with upline leak test tap, connector for rate of flow indicator, shut-off ball valve,<br />
galvanised steel delivery manifold with starting pressure switches and 15 bar expansion tank.<br />
The size of the hydraulic part is compliant with UNI 9490 - UNI 9489 - UNI 10779.<br />
ELECTRICAL CONTROL PANELS<br />
One IP 55 control panel for each electric pump with duplicated front-of-panel indicator LED's, general switch, fuses,<br />
direct starting contactors for electric pumps, 1 voltmeter and 1 ammeter, 12 Volt battery for alarm signalling with battery<br />
charger, AUT-0-MAN selector, START – STOP buttons, recessed selector for operation to UNI 10779, 1 outlet with<br />
switch. Alarm contacts inside terminal box for incorrect voltage and pressure drop are to be connected to an acoustic<br />
device (supplied with the booster set)<br />
Connector for weekly test unit (only for the main electric pumps).<br />
