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: Why should the pump be closed when the centrifugal pump is started?: Therefore to close the outlet valve, the pump during starting output water, the minimum pump power, when the pump reaches the rated speed, slowly open the outlet valve, gradually increase the flow of water, the motor current is gradually increased to the rated current.

Q: What are the reasons for sealing damage of centrifugal pumps?: The reasons for sealing damage of centrifugal pumps are as follows: six, the specific contents and handling methods are as follows:First, the centrifugal pump water quality is poor, containing particles.As a result of poor water quality, containing small particles and medium hydrochloride content is high, forming abrasive wear, centrifugal pump seal plane or pull the surface, resulting in groove, ring groove and so on.Treatment method: improve water pressure or medium, replace machine seal.

Q: If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?: Submersible pump even if it really leakage, it will not cause the fish electric shock. The so-called leakage is the submersible pump wire or shell broken, live parts and water contact, the most extreme test is a fire line directly into the fish tank

Q: Double floor sewage pump circuit diagram of a small problem: Question 3 when the water level is low, when the 1KA is connected, the pump will run depending on where your SS selector switch is located. Its left and right position, running pump and standby pump definition is different, left position is 1#, running 2# standby, right position is 2# running, 1# standby. Only inIn case the high level switch 2KA is connected, the standby pump may work at the same time.

Q: What's the difference between non negative pressure and variable frequency water pump?: When peak water is used, the fluctuation of water pressure will be the same for customers! Because the key to the fluctuation of hydraulic pressure is the flow rate of the pump and the lift of the pump. As long as the flow of the selected pump is large enough, the tank is large enough, the lift head is suitable, and the pressure fluctuation is relatively small. And the selection of non negative pressure and frequency conversion pump group is not directly related. If the municipal tap water pressure and water sufficient (large enough diameter), the use of non negative pressure is better. If the municipal tap water pressure and water shortage, you can only use the frequency converter pump + water tank, no negative pressure can not be used.

Q: What is the difference between centrifugal pump and positive displacement pump?: The centrifugal pump is usually driven by an impeller, and the head has a functional relationship with the flow rate. Positive displacement pump is gear or piston drive, each stroke output flow is constant, and the head does not matter, the pressure head can be infinite.

Q: Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?: Four) release bolus dosage method can use automatic release and manual release two ways, the key is to alarm after the infusion must be stopped(five) any kind of pill dose release are not restricted to replace the pill. The total dose limit for in pipe blockage after pill agglomeration process will remove blocking accident, this time will be the rapid infusion of pill dose concentration into the patient's blood, if the total dose pill does not get test and limit, rapid infusion of this accident it may have unimaginable consequences.(six) supplies open type infusion pump overflow on the domestic market for pill characteristic parameters of consumables simply without testing and limitation. Therefore, the risk of accidental pill has become one of the residual risk of open type infusion pump supplies the most deadly.

Q: How can I buy a pump?: Selection principle of pump:1, so that the selected pump type and performance parameters meet the unit flow, lift, pressure, temperature and other requirements, the most important thing is to determine the voltage, the maximum lift, and when the head high reached much traffic.

Q: What is an industrial water pump?: Industrial water pump, water pump for industrial production.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.

Q: Why can't the centrifugal pump pump the vacuum?: Working principle (taking centrifugal pump as an example):Prerequisites, processes, and requirements for the overall system structure.
