2,Axial suction centrifugal pump
Min inlet pressure
Min inlet pressure depends on NPSH +0.5m safety margin + gasified pressure. It should be re-calculated the inlet pressure if one of the following happens.
*The liquid is more warm.
*The flow exceeds the nominate value.
*Suction distnace is very long or inlet pipe is very long.
*System pressure is too little.
*Inlet pressure is low.
*Clean, thin, non-corrosive, non-flammable or non-explosive liquid without grain or fiber.
*Water supply system
*Heat, air condition system
*Booster, constant pressure water supply
*Industry cooling, heater circulation system
*Firefighting, splitting system
*Industry transferring, drainage system
*Non-self-priming, single stage, single suction, horizontal, axial suction and radical discharge, pump body is fixed by base.
*Use bering cradle, which can orientate bearing, prevent from radical vibration, improve the rigidity of rotary part.
*Compacted shaft, use deep grove grease lubricated roller bearing.
*Connect pump and motro with semi-flexible coupling.
*Use standard wearable mechanical seal.
*TEFC motor, size complies to IEC standard, installation type B3.
*The dimensions is conform to ISO 2858
*Flow: Max 520m3/h
*Head: Max 160m
*Liquid temperature: -15°C - 110°C
*Working pressure: Max 16bar
*Inlet and Outlet diameter: Inlet diameter: DN50-DN200; Outlet diameter: DN32-DN150
*Curves tolerance is according to ISO9906, Annex A;
*All curves are based on the measured value of constant motor speed 2900rpm, 2950rpm, 1450rpm or 1480rpm.
*The measurements were made with airless water at temperature of 20°C. The curves apply to a kinematic vis-cosity of 1 mm2/s (1 cst)
*Back-pull-out design, without having to disurb pump body and pipelines when servicing.
*All the models only use 4 kinds of pump shafts and bearing cover, make parts exchangeable.
*Impeller is optimum design, inlet is enlarged, no whirlpool, deduct the water pump NPSH efficiently, which makes pump work stable with little noise.
*Casing and casing cover use wearing neck ring structure, which makes pump easy to maintain, makes parts work longer. The replaceable seal ring, makes pump work efficiently in a long time.
