More about this product
Ebara EVMS-K10 6F5 Q1BEG E/2.2 TT Overview
The EVMS-K10 6F5 TT is the three-phase, round flange version of the 6-stage model in the EVMS-K10 range, Ebara’s 10 m³/h nominal-flow vertical multistage pump supplied complete with inverter control. The E-SPD+ unit is mounted on the motor terminal box, and the pressure transducer comes electrically connected. The inverter starts, stops and modulates motor speed to hold the set pressure, giving steadier supply, lower energy use and longer service life than fixed-speed operation.
Hydraulic parts are EN 1.4301 (AISI 304) stainless steel, with a tungsten carbide shaft sleeve bearing and a Q1BEG cartridge mechanical seal. A 2.2 kW IE3 two-pole motor drives it, and the DN40 round flange inlet and outlet sit in-line at the base, bolting straight to standard flanged pipework and valves. With around 65 m of head at shut-off, it suits house and low-rise building boosting, farms, commercial supply, irrigation and washing systems.

Performance
Approximate duty points at 50 Hz (full speed), read from the Ebara EVMS(.)-K10 6/2.2 curve (ISO 9906:2012 Grade 3B). The inverter reduces speed to hold the set pressure at lower demand.

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.
