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%.

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.

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.
