AV & EV Booster Sets
3). Overview:
KGN Pillinger
’s EV, AV pressure booster sets are designed to transfer and boost clean (potable)
water in water systems for domestic, commercial and industrial applications.
Basic Operation:
➢
The pumps are controlled via the variable speed drives (VSD) according to the system
requirements.
➢
The pressure vessel(s) will supply the initial demand.
➢
Once the pressure has dropped to the set control value, the VSD will start the first pumps
operation.
➢
If a greater water demand is placed upon the first pump, it will speed up until the subsequent
pumps are required to reach the demand.
➢
If/when the demand reduces, the speed of the pumps reduces until they stop.
➢
If the demand is reduced further, the last pump will fill the pressure vessel and then shut
down.
The pressure booster sets are built with identical pumps and controllers in parallel, mounted on a
common stand with suction & discharge manifolds, On-off valves, check valves, pressure gauge,
pressure transmitters and single or three phase control panel. The system must be installed with
pressure vessels. These are preinstalled, sized membrane vessels.
