API 610 Standard Pump

API610 BB2 pump China

Instruction

SOY series process pump is single stage double suction and between bearings, radial split and centerline supporting (the code BB4 in API), designing according to APl,the pump is applied in pumping the medium under the high temperature and pressure, or inflammable, explosive and toxic fluid.

 Performance

Flow                  Q : 95～1740m3/h

Head                 H : 38～280m

Temperature     T : -80～+450°C

 Applications

Petrochemical industry               Power station

Coalindustry                               Chemical industry

 Features

Pump casing: the double-volute structure reduces the radial thrust, the fluid that entering into impeller will be distributed evenly and symmetry. The suction and drain on casing, without dismantling the pipeline to replace the wear parts and rotor parts

Pump cover : the symmetry double pump cover structure, it is easily for maintains, The cooling chamber which could decrease the working temperature in seal chamber, which guarantees seal long running and reliability.

Impeller: the double suction impeller would automatic balance the axial force of rotor, which decrease the NPSHr.

Shaft: the rigidity Shaft designing could guarantee the pump running steadily under the working speed. The heavy-duty shaft is designed for adopting the suitable bearing span, which supplies the reliability and anti-turn safety, it is easily assembly when using the taper extended shaft.

The bearing: the equipped diagonal contacting ball bearing that would guarantee the load capacity in heavy duty. There are air cooling(t<120 °C), wind cooling (t=120°C-260°C) and water cooling (t=260°C-450 °C), which will decrease the bearing working temperature to improve the bearing life.

The seal and auxiliary system: completely according to the API682 with flushing pipeline and cooling system.

 Overview

Series SBR is a horizontal between bearings radially-split double-volute single-, two- or three-stage centrifugal pump. Two hydraulic powers of high efficiency and anti-cavitation can be selected for the impeller depending on the operation condition so that it can be used for a broader range of operation conditions.

Series HR pumps comply with the design requirements in API 61010th and API 610 11th. The product was designed by reference with the design and hydraulic performance of the most excellent similar products at home and abroad and by use of the advanced hydraulic power and strength analysis software. The strict international quality control system was applied in the process control of product to ensure that the overall performance of the product reaches the China-leading and world-advanced level.

 Application range
