Deep well electric pump ESPA ES4 3 21 O4I M 1.5 kW
ESPA ES4 3 21 O4I M (1.5 kW) is a reinforced high-head modification designed for intensive water extraction from deep wells and sources operating under demanding conditions. The floating impellers prevent jamming and increase the pump’s durability when handling water with small mechanical impurities.
Dual protection — a built-in check valve and a NEMA-standard adapter — ensures minimal vibration, stable operation and a safe, secure motor connection. This makes the pump an ideal choice for systems with frequent starts and high water consumption.
The model delivers high performance and is widely used in advanced autonomous water-supply systems, agricultural complexes, greenhouses and industrial installations.
Advantages of ES4 3 21 O4I M:
▪️ high power — 1.5 kW;
▪️ excellent head and stable water delivery;
