Key features

1.Radially split, between-bearing two-stage casing design Horizontal radially split barrel casing, double impeller in series layout. Split plane perpendicular to shaft centerline; casing owns outstand

2.Series twin-impeller hydraulic layout Two single-suction impellers mounted back-to-back, most axial force self-balanced inherently; only tiny residual axial load borne by thrust bearing.

3.High-rigidity robust rotor assembly Long rigid shaft with precision dynamic balance, compact bearing span to limit shaft deflection under high differential pressure. Standard replaceable shaft sleev

4.Full API610 standardized construction Seal chamber conforms to API682 / ISO21049, compatible with single / double mechanical seal + auxiliary flush plans. Optional oil bath, forced feed oil lubricat

5.Flexible material & medium compatibility Available in cast iron, carbon steel, stainless steel, duplex stainless steel. Suitable for clean / slightly corrosive low-viscosity process fluid, hot boile

Easy maintenance: Axially split casing, pull-out rotor without disconnecting piping or motor, short overhaul time.

Stable operation: Back-to-back impellers self-balance most axial thrust, low vibration, longer seal & bearing life.

High pressure capability: Multi-stage design delivers ultra-high head, eliminates complicated pump serial installation.

Excellent suction performance: Optional double-suction first impeller reduces NPSHR for poor inlet pressure conditions.

Wide applicability: Wide flow/head range, flexible material options for oil, petrochemical, power and corrosive media.

Its stated product range covers multistage, centrifugal, split-case, anti-corrosive, mining-water, oil, single-stage, seawater, chemical, and sewage pumps. The supplier reports ISO9001:2015 and ISO14001:2015 certification, four production lines, 21–30 quality-control staff, and annual output across several pump categories. Reported production includes 2,000 multistage, 1,200 split-case, 3,000 end-suction centrifugal, 1,000 long-shaft, and 4,000 submersible pump sets annually. It serves domestic and export markets and states one-month peak and off-peak lead times. Evidence supports manufacturing scale, product breadth, and formal management certifications. However, the provided information does not sufficiently establish after-sales service systems, financial credibility, customization processes, or named customer...

Supplier typeThe supplier is described as a limited company and factory in China, engaged in pump design, research, production, installation, and sales. It is specifically presented as a manufacturer of industrial and water pumps, with its head office and operations located in Hunan.

CertificationsThe supplier explicitly reports holding ISO9001:2015 and ISO14001:2015 certificates, along with other unspecified certifications. This provides direct evidence of certified quality-management and environmental-management systems.

R&D capabilityThe supplier explicitly describes pump design and research and development activities, including water-pump R&D, and reports seven years of total R&D-engineer experience. Its stated portfolio includes 26 product series and 2,160 specifications, supporting product-development breadth, although no patents, testing facilities, or recent innovation results are provided.

Production capacityThe supplier reports four production lines, 21–30 quality-control staff, and annual production across multiple pump categories, including 2,000 multistage, 1,200 split-case, 3,000 end-suction centrifugal, 1,000 long-shaft, and 4,000 submersible pump sets. The stated one-month lead time in both peak and off-peak seasons further supports operational capacity, although employee counts differ between company descriptions and should be confirmed.

Product Q&A

Q:Which mechanical seal plans available for BB1?

Standard API Plan11/21; optional Plan23/32/53A/B/C for high temp, volatile hydrocarbon & vacuum suction working condition.

Q:What is BB1 max flow capacity?

Standard BB1 single-stage axially split pump: normal range 20 ~15,000 m3/h, customized large-size model up to 40,000 m3/h; double suction impeller version covers ultra-high flow for pipeline & circulating water service

Q:What is BB1 maximum head?

A: Standard single-stage BB1 max head 150~200 m; 2-stage BB1 design can reach up to 350 m, max casing design pressure up to 34 bar (3.4 MPa).

Q:Working temperature range of BB1 pump?
