How to select correctly Bơm trục đứng đa tầng cánh

01

Xác định lưu lượng & cột áp

Cột áp cao (cao tầng, RO, boiler) cần số tầng cánh phù hợp; lưu lượng quyết định cỡ bơm.

02

Chọn vật liệu

Inox 304 cho nước sạch; inox 316 cho ăn mòn nhẹ và yêu cầu vệ sinh cao.

03

Chọn dòng & thương hiệu

DRL cho áp 35–40 bar; XR(L) inox 316 cho cột áp tới ~350 m. Kỹ sư TKT tư vấn theo CO-CQ.

Handles viscous, particle-laden, shear-sensitive fluids — including ATEX explosive atmospheres.

Selection guide

Diaphragm pump selection theo bộ ba

No single diaphragm pump configuration fits all fluids. Select by the trio: fluid × wetted materials (body + diaphragm/ball) × port size & flow rate. Hai bảng dưới ánh xạ nhanh yêu cầu thực tế sang cấu hình phù hợp.

Selection guide

Khi nào chọn bơm trục đứng đa tầng

Bơm trục đứng đa tầng cánh đạt cột áp cao mà vẫn gọn mặt bằng (in-line). Phù hợp cấp nước cao tầng, RO/lọc màng và boiler feed. Thân inox 316.

⚠️ Đa tầng đứng cho cột áp cao & mặt bằng hẹp; lưu lượng lớn cột áp thấp nên dùng hỗn lưu/trục ngang. Khi ghép biến tần + tủ thành hệ thì là hệ tăng áp. Hướng dẫn chung — kỹ sư TKT tư vấn →

Questions frequently asked

A vertical multistage centrifugal pump has a vertical shaft with multiple impeller stages in series to achieve high head while saving floor space. Stainless steel casing is suitable for clean water and mildly corrosive fluids.

Depends on the number of stages and model; the XR(L) Inox 316 series achieves head up to ~350 m. Exact figures vary by model — contact TKT engineers.

Inox 304 for clean water; Inox 316 for mildly corrosive fluids and hygiene requirements. Selection depends on fluid type and environment.

The vertical multistage pump is the pump unit itself; when combined with a variable frequency drive, control panel, and pressure vessel into a system, it is called a pressure booster system. See also the Booster Pump page.
