centrifugal pump dab KVE 3-6-10
centrifugal pump dab KVE 3-6-10Vertical multistage centrifugal pumps of this series are designed for water supply and pressure boosting systems. The presence of the MCE/P inverter provides high operational flexibility, allowing the pump to automatically adapt to different system requirements and maintain a constant pressure in it. These pumps are recommended for use in pressure boosting stations, drip and sprinkler irrigation systems, high-pressure washers.

DESIGN FEATURES
Casing of the pressure and suction chambers – cast iron with anti-corrosion coating. Impellers, diffusers and diffuser covers – technopolymer. Hydraulic housing, hydraulic shaft and wear rings – stainless steel steel. The bearing of the centering diffuser is made of bronze and is lubricated by the pumped liquid. Mechanical seal – graphite/ceramic. The engine and hydraulic shafts are connected by a rigid coupling. The pumps are equipped with an air-cooled asynchronous electric motor. The delivery set includes threaded counter flanges.
