Product Introduction
▼ The Vertical Multi-stage Series Pump is a high-efficiency centrifugal pump designed for water boosting and liquid transfer. Its compact vertical structure saves installation space while delivering stable high pressure for building water supply, water treatment, industrial circulation and municipal water boost applications.
▼ With flow rates from 1 to 50 m³/h and heads from 20 to 200 m, the pump can be configured according to project-specific hydraulic requirements. Stainless steel and cast iron wetted parts are available to handle clean water or slightly corrosive media for different working conditions and local project standards.
▼ Each pump is performance tested before shipment, and technical documentation, dimensional drawings and selection support can be provided for project evaluation.

Product Advantages
The pump adopts optimized hydraulic design and stainless steel multi-stage impellers, delivering stable high pressure output with high working efficiency. Its polished stainless steel flow components effectively resist rust and slight corrosion, guaranteeing clean medium and long service life for water supply and water treatment projects.
01
Compact vertical structure greatly reduces floor space requirement, which is ideal for limited-space equipment rooms. The inline connection design simplifies installation work, and the open structure makes daily inspection and component maintenance convenient without removing the whole pump unit.
02
It is equipped with high-quality mechanical seal and high-standard IP55 protected motor. The rotor assembly undergoes precise dynamic balance treatment to achieve low vibration and low noise during continuous 24-hour operation, suitable for commercial buildings, residential areas and industrial sites with strict noise requirements.
03
Wide performance range with flexible stage quantity adjustment, enabling customized flow and head to match diverse working conditions. Multiple material options, different voltage and frequency selections are available to satisfy various project standards and different liquid transfer demands.
04
Every pump unit passes strict full-performance test before delivery to verify flow, head and sealing performance. Complete technical drawings, parameter sheets and professional selection support are provided, helping customers finish project evaluation and system design smoothly.
