Overview

KBF series pumps are multi-stage centrifugal pumps of horizontal, double-casing, inner core segment, impeller in the same direction, first-stage single-suction or double-suction design. The design standard is API 610 11th and API code is BB5.

KBH series pumps are multi-stage centrifugal pumps of horizontal, double-shell, axial core split, volute, symmetrical arrangement in impeller, first-stage single-suction or double-suction design. The design standard is API 610 11th and API code is BB5.

Application Range

KBF series pumps are mainly used in boiler feed water, refineries, thermal power plants, coal chemical industry, urban water supply, water treatment, petrochemical and other industries. It is especially suitable for conveying liquids, flammable, explosive, toxic, high temperature and high pressure, such as liquefied petroleum gas, light hydrocarbons, boiler feed water, etc.

KBH series pumps are mainly used in oil exploitation, coal chemical industry, seawater desalination, power plants and so on. It can also be used in gray water pump, lean methanol pump, chemical fertilizer, lean liquid pump and rich liquid pump in coal chemical industry.

Structural Features

① The pressure parts of the pump body and pump cover are made by forging process, which makes the operation safer and more reliable.

② Both pump body and impeller are provided with a sealing ring. The clearance and hardness are in accordance with API 610 standard. The spare parts are easy to be replaced and have a long service life.

③ There are guide keys and positioning pins. When conveying high temperature medium, the pump expands and extends to the non-driven end, which does not affect the connection between pump and drive machine. The operation is safer and more reliable.

④ Self-lubricating sliding bearings and forced lubrication sliding bearing structures can be used depending on the shaft power and the speed.

⑤ The inner core adopts the integral extraction structure, which can realize the maintenance and inspection of the pump without moving the inlet and outlet pipelines.
