Calpeda Easymat 3MXH1603-EMT-24 is a Calpeda Easymat triple-pump variable-speed booster set with Calpeda MXH 1603 horizontal multi-stage pumps, part number U83004800000. Each pump gives up to 417 l/min (25 m³/h) and up to 36 m (3.5 bar) at full speed.
Easymat is Calpeda's variable-speed controller: its frequency inverter holds a constant pressure as the flow demand changes, so the pumps only use the energy the system needs. Calpeda lists these sets as 230 V single-phase in, 230 V three-phase out to the motors.

What is a water booster pump?
A water booster pump increases the pressure of an existing water supply to give stronger flow at taps, showers and appliances. It can be a small inline pump fitted to the incoming mains, or a larger pump and tank set that draws from a break tank to feed the whole house. Boosters do not create water – they raise the pressure of the water already coming in.
What is the difference between an inline booster and a tank-and-pump booster?
An inline booster connects straight onto the incoming mains and is limited to 12 litres per minute under UK water regulations – examples include the Salamander HomeBoost and WaterBoost WB-Compact. A tank-and-pump booster, such as the Grundfos Home Booster or DAB Esybox with Esytank, draws from a break tank and can deliver much higher flow rates for larger homes with multiple bathrooms.
What is a variable speed booster pump?
A variable speed booster uses an inverter to adjust pump speed in real time to match demand. It maintains constant pressure as outlets open and close, runs more quietly than a fixed-speed pump and typically saves up to 50 per cent of the energy a fixed-speed equivalent would use. The DAB Esybox, DAB Esybox Mini 3 and Grundfos Scala2 are common variable speed examples.
What does a water booster pump do?
A water booster pump raises water pressure to help supply taps, showers and other outlets when the existing system cannot meet demand.
Can a booster pump connect directly to the water mains?
Not every booster can. Direct connection depends on the product design and applicable water regulations; some systems require a break tank.
How do I size a water booster pump?
Assess simultaneous flow demand, required outlet pressure, available inlet conditions and the pressure losses in the pipework.
What types of Calpeda pumps can I explore?
Calpeda produces pumps for water supply, pressure boosting, drainage and circulation. Choose a model according to the required flow, head and liquid.
Are Calpeda pumps suitable for commercial installations?
Yes. Calpeda offers pump ranges for domestic, commercial and industrial duties; suitability depends on the individual model and duty point.
How do I choose a replacement Calpeda pump?
Check the existing pump model, supply voltage, connection dimensions, flow rate and required head before selecting a replacement.
