Thousands of Grundfos Hydro MPC boosters are alreadyproviding consumers with constant water pressure. Eachbooster is a fullyintegrated turnkey unit based on theextremely reliable, high-efficiency CR pump and theControl MPC multi-pump controller. The system ensurescomplete and instant control and unbeatable efficiency,while keeping leakage loss down.

proportional pressurecontrol a uniqueway to save moneyLower leakage losses
Proportional pressure control
ensures constant tap pressure at
the consumer as opposed to a
constant pump discharge pressure.
Automatic setpoint reduction
typically reduces leakage by 5-20%
sometimes by as much as 50%.

50%, you reduce leakage loss by at
least 30%.

A big pump has a big water hammer
effect; this is a factor of the pumpsinertia. Smaller pumps reduce the risk ofwater hammer. The purchase price and
operating costs are also lower.
Sudden momentum changes thatcause water hammer can be avoidedby a gradual ramp-up, likewise withramping down. This is a standard
pre-programmed function in theGrundfos Control MPC.
Proportional pressure controlautomatically regulates the set-point to minimise water loss andenergy consumption. This is uniqueto Grundfos Control MPC.

new cost-effectivedesign principles
Lower capital investment
Compared to traditional set-ups,
the design principle described here
reduces initial capital investment.
When converting existing systems,
payback time is typically within 1-3
years.

Cut energy consumptionby 50%
Many system designers claim that
as much as 50% of the pump energy
consumption can be saved.
This claim is substantiated by the
many pump audits Grundfos has
performed around the world.
A Grundfos Pump Audit is an exceptionaland well-proven tool that enables the
water supplier to prioritise investmentsin energy reduction.
A pump audit is a step-by-step process to identify potential energy-saving investments.Payback times are most commonly 6-24 months.

Made for each other
The hydraulics, motors and elec-
tronics on Grundfos systems are
specifically developed for pump
operation. Motors are optimised
to the pumps duty range, typical
pump functionalities are built into
pump controllers, and communica-
tion interfaces are pre-programmed
for data exchange to and from central
SCADA systems.
