Multistage centrifugal surface pump ESPA TECNO 25 4M

The multistage surface pump ESPA TECNO 25 4M is a reliable single-phase model designed for residential, agricultural and industrial water supply systems that require stable pressure, economical operation and low noise levels. It is intended for pumping clean water from wells, tanks, lakes, boreholes and other sources free of mechanical impurities. The pump performs equally well in autonomous water systems and in pressure-boosting stations.

One of the key advantages of the TECNO 25 4M is its self-priming capability: with an unfilled suction pipe it can lift water from 2 meters, and with a fully primed suction line – up to 9 meters. This makes the unit versatile and suitable for locations with different water-intake depths.

The hydraulic section uses a multistage centrifugal design with closed impellers, ensuring a smooth and stable water flow. The mechanical shaft seal prevents leaks and extends the lifespan of the hydraulic unit. The forced air-cooling system of the motor improves thermal performance and prevents overheating, even during prolonged operation under load.

ESPA TECNO 25 4M is widely used for potable water supply, feeding household appliances, irrigation and automatic watering, filling swimming pools and tanks, supplying small washing systems, as well as for general domestic and utility needs. The pump features low noise levels, stable operation, compatibility with frequency converters and minimal maintenance requirements.
