Specifications

1,Single-stage single-suction 
2,Axial suction centrifugal pump 
3,Back-pull-out design

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.

 

Typical application

*Clean, thin, non-corrosive, non-flammable or non-explosive liquid without grain or fiber.

*Water supply system

*Heat, air condition system

*Irrigating, farming

*Booster, constant pressure water supply

*Industry cooling, heater circulation system

*Firefighting, splitting system

*Industry transferring, drainage system

 

Construction

*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

 

Specificaton

*Flow: Max 520m3/h

*Power:Max 160Kw

*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

 

Curve conditions

*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)

 

Features

*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.


Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines? Why?
Reasonable, no valve, how to debug, overhaulGenerally installed on imports of valves of relatively large Cv value
Q:I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?
(4) before installation, make sure all pipes connected with the pump should be clean, and no solid foreign bodies which may cause damage to the pump shall be allowed.(5) apply the blind flange or other things to the suction, exhaust or open pump to ensure that no sundries enter the pump cavity during the installation.(6) check whether the pump random data is complete and complete; whether the pump surface has obvious damage. Only with complete data, no obvious damage to the pump, you can continue to install.(7) the installation of centrifugal pump with the coupling of the hand when turning slowly rotating coupling or pulley, observe the pump rotation are stable, flexible and adjustable, the rotor parts have no jamming, the pump has no debris crash, bearing the operation is normal, with elastic suitability.
Q:What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?
Displacement of a pump: the volume of the discharged liquid calculated by the change in the size of the sealing geometry for each revolution of the hydraulic pump
Q:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
Pigment pressure is less than 0.4mpa,About 0.3. Go up.As the pump diaphragm is in the middle of a connecting rod, equivalent to the cylinder cavity, the pressure will be reduced; and because of the loss of pigment tube pressure will be reduced.
Q:Does vacuum pump oil belong to dangerous goods?
Absolutely not. We often send oil by express or by freight. There are no problems at all. Don't be afraid, don't burn, explode
Q:Fire hydrant pump button, under what circumstances do not need to install?
General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.
Q:Metering pumps related matters
Rotate to stroke length 100% position. This allows the kit to rotate to the back of the drain hole and align the bottom of the pump. Adjust the hydraulic end and diaphragm to the proper position during the pump operation.The duration of the pulse may not be long enough for the reaction time. With respect to the standard pulse width 80msec, the flow monitor pulse width expansion can be activated, increasing the pulse width to 300msec. Activate the smart switch, remove the cover fixed circuit board, remove the jumper X-1. This activates the extended function and allows more time before the failure instructions.Metering pump installed from the exhaust pump head, the use of self suction liquid imbibition. Keep the suction line as short as possible.
Q:What is the pumping property of concrete?
Pumping capacity means that fresh concrete can be transported by concrete pump, and concrete construction can be carried out with high efficiency. 'pumping' is a qualitative statement
Q:What is a positive displacement pump? He Weizheng displacement?
Includes a pump housing (10), a pump chamber (24), the pump chamber has an entrance channel (21) and an outlet check valve (17) export control channel (28), a displacement member (13), the definition of the pump cavity in a direction of movement in (24) and in a stroke section in the pump cavity (S) in reciprocating motion
Q:What is a vacuum pump for?
In fact, the vacuum pump and high Swiss fan, high Swiss high-pressure blower, high Rui high-pressure pump principle is almost the same
