Import Dg Series High Pressure Boiler Water Pumps — Buy in Bulk from Supplier in China

The DG series High Pressure Boiler Water Pumps are centrifugal pumps engineered for continuous operation in industrial boiler systems requiring pressures up to 16 bar. These units feature multi-stage impellers constructed from cast iron or stainless steel, with mechanical seals rated for high-temperature water service. The design complies with ISO 5199 and ANSI B73.1 standards for pump construction, ensuring compatibility with standard piping and mounting interfaces.

Typical flow rates range from 5 to 50 cubic meters per hour, with suction and discharge ports sized from DN50 to DN150. The pumps operate at speeds between 1450 and 2900 rpm, depending on motor configuration. Bearings are grease-lubricated and housed in sealed housings to prevent contamination, while the casing is designed to withstand thermal shock from sudden temperature changes during boiler startup. Standard coatings include epoxy paint for external surfaces, with optional stainless steel wetted parts for corrosive water conditions.

These pumps are commonly purchased by power plant operators, chemical processing facilities, and district heating contractors in Asia and Eastern Europe. Buyers typically require units with variable frequency drives for load matching and remote monitoring interfaces. Trade terms are usually FOB Dalian or CIF destination port, with minimum order quantities starting at one unit for sample evaluation and bulk orders negotiable upon technical confirmation. Packaging includes wooden crates with moisture barriers and lifting lugs for safe handling.
