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: How to adjust the flow of piston pump?: The oil pan with oil liquid through the suction port and the piston cylinder; from 180 degrees to 360 degrees, the piston cylinder volume decreases, so the oil liquid in the pan with oil discharged from the outlet of the liquid. The pump works continuously as long as the drive shaft rotates.

Q: Fire pump and shower pump flow head selection, high resolution.: 3, larger than 25000, the minimum water consumption of indoor fire hydrant is 20L/s4, the minimum water consumption is the flow of a fire hydrant.

Q: What does "anti pump" mean in pump operation?: Function: anti pump effect when used for pumping concrete pumping occurs overpressure, the pumping pressure is above 25MPA, the concrete conveying pipe out of ash, can be understood as the precursor of pipe blockage, at this time should immediately use the anti pump, the concrete from the conveying pipe in the suction into the hopper, thus preventing plugging happen

Q: How many kinds of pumps are available and the operating principles of various pumps?: The volume type pump, depending on the periodic change of sealing liquid containing space volume, the energy is periodically transmitted to the liquid, the liquid pressure increased to force the liquid discharge, according to the motion form of work elements can be divided into reciprocating pump and rotary pump. Other types of pumps transmit energy in other forms. As the jet pump work on high-speed jet of fluid will be required to transport fluid suction pump after mixing for momentum exchange in order to transfer energy; water hammer pump by water when braking in the flow of energy transfer is to rise to a certain height; the electromagnetic pump is energized to make the liquid metal in the electromagnetic forces generated in the flow and transport. In addition, the pump can also be classified according to the nature of the transmission fluid, driving methods, structure, use and so on.

Q: Why can the centrifugal pump hold down the pressure?: Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. Vertical centrifugal pump is referred to as submerged pump, molten salt pump and submerged pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work.

Q: What does "efficiency" mean in a water pump catalog?: General pump efficiency is 60% ~ 85%. high efficiency of the pump, indicating the same work, the pump consumes the lowest energy, and vice versa

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?: (8) check the suitability of the foundation and whether the size of the foundation corresponds to the size of the pump.(9) find the position of positive pump and motor, pump set and anchor bolt and the inlet and outlet flanges, to ensure that the flange torque of the pump conforms to the standard. Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition. It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.

Q: What is the working pressure of the hydraulic pump in the hydraulic transmission system?: Generally speaking, for the fixed size, not limited equipment, the pressure can be selected lower, walking machinery heavy equipment pressure should be selected higher.If the load is selected, the working pressure is as follows:Load <5kN, working pressure <0.8~1MPa;Load 5~10kN, working pressure 1.5~2MPa;Load 10~20kN, working pressure 2.5~3MPa;Load 20~30kN, working pressure 3~4MPa;Load 30~50kN, working pressure 4~5MPa;Load 50kN, working pressure =5MPa;For example, the system work pressure of various machines is as follows:Grinder 0.8~2MPaModular machine tool 3~5MPaLongmen planer 2~8MPaBroaching machine 8~10MPa agricultural machinery, small construction machinery, construction machinery, hydraulic drilling machine 10~18MPa hydraulic machine, large and medium-sized excavators, heavy machinery, lifting transportation machinery 20~32MPa.

Q: How many square cables does the submersible pump for 7.5KW need?: 7.5KW's submersible pump requires 2.5 square aluminum cables.Calculate the current value of submersible pump first:

Q: What is the cause of the damage of pump bearings?: First of all, know your pump model, and what is the bad bearing, in order to accurately judge for you. Because in addition to some common reasons, the structure of different pumps, bearing damage caused by the reasons are different. Otherwise it is fraught with itching shoes.
