DL/DLR Vertical Multi-stage Hot Water Centrifugal Pump

I. Overview

DL series pumps are vertical, single-stage, multi-stage, segmented centrifugal pumps for the transportation of clear water and liquids with physical and chemical properties similar to water below 80°C. The temperature of the DLR-type hot water pump conveying medium is below 150°C.

II. Characteristics:

The pump is installed vertically. It has the characteristics of compact structure, low noise and small footprint. It is mainly used in urban water supply and central heating systems, high-level water supply, and fire-fighting water pumps.

III. Pump model meaning:

Such as 65DL-5 65DLR-5

DL-vertical multi-stage segmented centrifugal pump, DLR-vertical multi-stage segmented hot water centrifugal pump. 5-impeller number
