📘 Product Overview
The D series horizontal multistage centrifugal pump is engineered with multiple single-stage pumps connected in series. By utilizing impeller rotation to generate centrifugal force, it achieves high output water pressure and significant vacuum levels once concentration requirements are met.
This mechanical vacuum pump operates based on the volume change within the pump cavity for air suction, compression, and exhaust. A key advantage of the horizontal single-suction design is the ability to adjust the number of stages to match specific practical working pressures. These pumps are highly efficient, reliable, and durable, offering quiet performance and low-maintenance operation across a wide range of industrial applications.
