centrifugal pump dab KVCE 30-50-80-120
centrifugal pump dab KVCE 30-50-80-120vertical 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 booster stations, drip and sprinkler irrigation systems, and high-pressure washers. They feature an innovative and reliable design.

DESIGN FEATURES
The hydraulic housing with connecting holes is made of technopolymer. The connecting holes are located in-line and equipped with metal threaded inserts. Impellers, diffusers and diffuser covers – technopolymer. Hydraulic housing, wear rings and mechanical seal flange – stainless steel AISI 304 steel. Mechanical seal – graphite/ceramics; motor shaft – stainless steel AISI 303 steel. The pumps are equipped with an air-cooled asynchronous electric motor. The motor shaft rotates on oversized bearings, ensuring low noise levels and long engine life. The design of the motor complies with CEI 2-3 and CEI 61-69 (EN 60335-2-41) standards.
