Our standard single-stage API 610 BB2 type pumps are center line-mounted, radially split, and feature a double-suction design with bearings located between the suction and discharge ends.
These pumps and their motors are flexibly coupled and mounted on a shared base plate.
The radial casing pull-out design allows for the removal of the rotor assembly without the need to disturb the driver, coupling hubs, or casing nozzle connections
High-pressure reciprocating pumps are usually used in small and medium flow and high pressure conditions, and can replace high-speed pumps and multi-stage pumps to a certain extent.
The high-pressure reciprocating pumps developed by our company have been successfully applied in fertilizer plant methyl ammonia pumps, liquid ammonia pumps, dimethyl pumps, BDO plant BYD high-pressure feed pumps, hydrogenation plant high-pressure water injection pumps and other fields, with a maximum flow rate of 100m3/h and a maximum discharge pressure of 50MPa.
Huasheng Pumps and Valves has obtained "multiple invention patents" around the research on the structure of reciprocating pumps and diaphragm pumps. The company's new products such as chemical hydrogenation water injection high-pressure reciprocating pumps, BDO plant BYD feed pumps, water-coal slurry, and high-pressure diaphragm pumps have completely replaced imports and filled the domestic gap.
The BB5 type pumps are double casing, radially split multistage between bearing pumps conforming to API 610 requirements.
These pumps are suitable for wide applications in high pressure fluid handling in oil refineries and petrochemical industry.
The discharge pressures are designed up to class 2500 and suitable for suction pressures up to 79 bar (g).
Our BB5 multi-stage, double-casing, centrifugal pumps are engineered for reliable 20-year operation, well proven with over 1,000 units installed worldwide.
They’re highly efficient with an optimized hydraulic design that provides low net positive suction head (NPSH)—close to the maximum theoretical threshold.
