VMA END SUCTION BARE SHAFT CENTRIFUGAL PUMP

The VMA bare shaft centrifugal pump is engineered with a larger inlet than outlet, allowing for sufficient water intake that reduces turbulence and minimizes the Net Positive Suction Head Required (NPSHr). This design enhances hydraulic stability, lowers noise levels, and reduces the risk of cavitation, ensuring smooth and reliable operation.

Developed using advanced hydraulic simulation technology, the VMA series delivers a stable and efficient performance curve. The optimized internal flow path minimizes energy losses, providing consistent efficiency and dependable operation even under varying system loads.

A key advantage of the VMA bare shaft design is its power flexibility. The pump can be coupled with either an electric motor or a diesel engine, depending on the operational requirements, site conditions, or emergency backup needs. This adaptability makes it suitable for a wide range of installations and applications.The bare shaft configuration simplifies integration into different pumping systems. It allows for customized assembly with user-preferred drive components, ensuring maximum compatibility and tailored performance.
