Horizontal Single Stage Centrifugal Pump

The D.DG.DGR series pumps are Horizontal Single Stage Centrifugal Pump units primarily intended for medium and low pressure boiler water supply, as well as other medium and low pressure clean water applications. By adopting a horizontal single stage layout, each pump provides a straightforward, compact structure that simplifies on-site installation and routine maintenance, while delivering steady, dependable performance across its working range.

Temperature limits are clearly defined for each model to match specific operating conditions: the D type is suitable for water temperatures not exceeding 80 °C, making it a practical choice for general water supply and lower-temperature boiler feed; the DG type handles water up to 110 °C, fitting many mid-temperature boiler circuits; and the DGR type is rated for water temperatures up to 160 °C, covering higher-temperature hot water circulation and boiler feed where greater thermal resistance is required. The allowable pH range of the pumped liquid is 6–8, which helps protect pump internals against aggressive acidity or alkalinity in normal clean water services.

This Horizontal Single Stage Centrifugal Pump series is well suited to a variety of applications, including building water supply, heating system circulation, industrial boosting, and medium or low pressure boiler feed systems. With its simple single-impeller construction, the pump keeps initial costs and maintenance workloads low, while the thermally graded model lineup lets users select the right temperature class for their system. The result is a durable, easy-to-service Horizontal Single Stage Centrifugal Pump that provides reliable water transfer over long operating periods with minimal complication.
