Chemical Pump BB1

Description

This series of pumps is primarily used in industries and fields such as refineries, petrochemical plants, cryogenic engineering, coal chemical plants, power plants, environmental protection projects, sewage treatment, and cement plants. They are suitable for conveying media such as circulating water and wastewater in chemical processes.

Compared to other pumps of the same type, SDP’s horizontal split-case pumps feature extended service life, high efficiency, rational design, low operating costs, and convenient installation and maintenance. They are ideal pumps for fire protection, air conditioning, chemical processing, water treatment, and other industries.

Pump Housing The pump housing is designed for pressures of 1.6MPa and 2.0MPa. To meet global user requirements, corresponding inlet and outlet flanges can be selected according to standards such as ANSI, PN, and JIS. Both inlet and outlet flanges are located on the lower housing, enabling rotor removal without disassembling the system piping for convenient maintenance. Some pump bodies feature a dual-channel design to reduce radial forces, thereby extending the service life of mechanical seals and bearings.

The impeller’s hydraulic design employs advanced CFD technology, thereby enhancing the pump’s smooth operation.

The thicker uranium shaft diameter and shorter bearing spacing reduce shaft deflection, thereby extending the service life of the mechanical seal and bearings.

Bushings For all pumps, bushings can be made from a variety of different materials to prevent shaft corrosion and wear. Bushings are replaceable.

Wear rings are employed between the pump casing and impeller, featuring replaceable wear rings to prevent wear on both components. This design facilitates easy replacement, minimizes maintenance costs, and ensures consistent operating clearances with high efficiency.

The packing body design can utilize either packing or mechanical seals, allowing for seal replacement without removing the pump cover.

The unique bearing housing design allows for either grease or oil lubrication, with a design life exceeding 100,000 hours. It can also accommodate double-row thrust bearings and sealed bearings.
