API 610 OH & BB Pump
API 610 OH pump for Chemical
API 610 BB3 & BB5 pump for Chemical
API OH Pump
API 610/ISO13709 Type OH Single-Stage End Suction Pump, is designed in accordance with ASME requirements to provide a high degree of dependability
It is Horizontal, centerline mounted, centrifugal pumps for Heavy duty applications A closed impeller and dual volute casing, and the use a tangential discharge to Maximize reliability and hydraulic efficiency.
The shell supports are specifically designed to ensure proper alignment of the shaft across all operating conditions. This feature, coupled with high-strength shaft design, means minimal shaft deflection, which results in creased life for the rotor, bearings, seals, and wear ring.

API 610 BB3 & BB5 pump for Chemical
Product type-description:
BB (Between Bearings ) Type petrochemical process pump is a two-end supporting centrifugal pump of horizontal type ,multi-stage, first stage double suction or single suction, longitudinally split.It is designed according to API610 standard,BB3 or BB5 type.Its impellers are arranged symmetrically to balance axial force,which reduces the failure rate of balance mechanism. Its inlet and outlet are on the bottom, so this pump can be disassembled without moving pipes in the course of maintenance and repair.
BB3 Type
Parameters:
Standard:API610
Capacity:20~2500 m3/h
Head: 70~1200m
Pressure:15MPa
Temperature:-40~200ºC
Applications:
Coal chemical industry,
Pipeline transportation,
Chemical fertilizer production,
Turbine, water treatment and all kinds of power plants.
Key Features:
this series of pumps is suitable for conveying neutral or corrosive, clean or particle-containing liquid.
Key Benefits:
No leakage
No external lubrication
Compact design
Introduction:
1.Conical shaft end is convenient for assembly and disassembly.Site seal replacement,normal maintenance etc are also convenient.
2.API682 standard seal chamber,and different seal forms can be configured according to operating conditions and user requirements.
3.All wear-ring, interstage bush and throttle clearance use non-occlusal pairing materials that have high hardness .Higher hardness can be achieved through surface treatment,thus wear media such as solid particles are conveyed.
4.Impeller heating assembly,and interference fit.The entire rotor has good rigidity and small deflection,which ensure running clearance and stable operation.Symmetrical impeller arrangement;self-balancing axial force.
5.Split type pump body is convenient for assembly.Double volute makes self-balancing axial force.Pump casing has good intensity and rigidity through exact calculation,which enhance the reliability and stability of operation.
6.Pump inlet and outlet are at the bottom of pump body.It only needs to open upper cover of pump body in the course of maintenance and repair.There’s no need to move the pipeline, thus reduce maintenance time and improve maintenance efficiency.
7.Many kinds of bearing forms for different powers. The housing reserves various kinds of instrument interfaces for users to choose. Dust-proof structure is designed to prevent oil leaking and dust entering the box.
Applications:
All kinds of clean or flammable,
Explosive, toxic liquid such as oil, refined oil, liquefied petroleum gas, light hydrocarbon, Boiler feed water, etc.
Parameters:
Flow Range：3～1000m³/h
Head：～3000m
Pressure:
Design Pressure 15.0MPa（Conventional Design）
High Pressure Design 35.0MPa
Temperature：-80℃～450℃
Key Features:
