Ebara 1 GPE Variable Speed Booster Set
Ebara 1 GPE Matrix 5-7T/1.5 ESPM – 230v – 2002470105
- Established 1975
- Trusted by thousands of customers
The Ebara 1GPE MATRIX 5-7T/1.5 ESPM is a compact single-pump variable speed booster set. A seven-stage Matrix 5 horizontal multistage pump in AISI 304 stainless steel, with a 1.5 kW IE3 motor, carries a motor-mounted E-SPD+ inverter, pressure transmitter, five-way check valve, membrane vessel and pressure gauge, so it arrives ready to connect.
The drive holds a constant set pressure as demand changes, from 1.8 m³/h up to about 5.4 m³/h, the end of Ebara’s application range for this set. It runs from a 230 V single-phase supply and connects through a G1¼ suction and a G1 discharge.

Ebara 1GPE MATRIX 5-7T/1.5 ESPM Overview
The 1GPE MATRIX 5-7T/1.5 ESPM is the seven-stage, 1.5 kW model in Ebara’s one-pump Matrix 5 GPE booster range. It is a single seven-stage Matrix 5 horizontal multistage pump with its 1.5 kW IE3 motor, a motor-mounted E-SPD+ inverter and pressure transmitter, and a five-way check valve on the discharge that carries the membrane vessel and pressure gauge. Everything is built onto the pump, so it installs much like a single pump.
The E-SPD+ changes pump speed to hold a constant set pressure, speeding up as taps open and slowing as demand falls. That gives steadier pressure, lower energy use and less wear than a fixed-speed pump with a pressure switch. The set delivers from 1.8 m³/h up to about 5.4 m³/h within Ebara’s application range, with around 80.5 m of head at shut-off. It suits houses, flats, small commercial buildings and irrigation where demand varies through the day and only a single-phase supply is available.

Performance
Duty points at 50 Hz (full speed), from the Ebara 1GPE MATRIX 5-7T/1.5 ESPM curve (ISO 9906:2012 Grade 3B). The 0 and 1.8 m³/h figures are Ebara’s stated values; the others are read from the curve. The table stops at about 5.4 m³/h, where Ebara’s application range for this set ends, at the point where the pump’s shaft power reaches its 1.5 kW motor rating. The drive 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.
