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 distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?: The unit of displacement is the milliliter. How many milliliters does the pump rotate per circle? The displacement is the pump, the individual,The unit of flow is generally a liter, a figure added to the displacement of the pump over a period of time,

Q:The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?: Difference：The installation position is different: one can discharge water, one is on the ground.The work principle is different: the principle of submersible pump is similar to the electric fan, centrifugal pump through centrifugal force to make the water throw out. According to the principle of centrifugal force design,

Q:What is the distance between the pump and the wall?: What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.

Q:Significance of water pump model ISO50-160: 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 parameters include flow, suction, lift, shaft power, water power, efficiency and so on;

Q:How is the pump level of submersible sewage pump determined?: Generally as:The bottom elevation of sump sump plus 300 is the water level of pump stopThe top 300 of the sump top elevation is the pump water level

Q:If the calculation of the required pump flow is 45, lift 110, and the actual pump flow 100, head 125, what will happen in operation? Can I use it properly?: First of all, the performance curve of the centrifugal pump is similar to the track of the train, and the train can not run away from the track.Secondly, the performance curves of centrifugal pump mainly include flow head curve, efficiency flow curve, power flow curve. When the pump is ready, the curve is fixed. In practical application, after determining the flow rate, the corresponding lift head, efficiency and power (relative to density) are determined. General requirements for centrifugal pump operating in the vicinity at the highest point of efficiency, the efficiency of the flow curve is similar to parabola, so if the actual operation condition deviated from the rated point, whether large or small, will cause the decline in pump efficiency (generally rated value is less than 15%), increased operating costs.

Q:Pump operator's responsibility 10Sharing the rules, responsibilities, etc..: 7., master the knowledge of concrete mix ratio, strictly forbid to add water to the pump at will.8., concrete mixing and workability, gravel diameter is too large, effectively refuse to pump.9. when the delivery pump fails, it can analyze the cause and quickly eliminate the trouble.10. pump complete, you must clean the pump body and pressure pipe residual.11. complete other temporary work assigned by the leader.

Q:What are the differences between the sewage pump and the clean water pump?: 2. in order to prevent the wound, water pump impeller design is more simple but not ring pump, equipped with tips, cloth and other debris can be crushed after the pump, and the impeller water pump is relatively complex, but the efficiency will be significantly higher than the former.Why can't the sewage water pump and impeller: because features of key design, resulting in water pump for sewage situation is likely to occur, blocking, winding, wear and corrosion occurs, resulting in damage to pump or scrapped, so water pump can not be used for sewage.

Q:How to maintain and repair the booster pump of pipeline pump?: Installation and use1. use rubber washer and bolt to connect the pump flange at both ends and the pipe flange. In order to use and maintenance convenience, in the pump inlet and outlet pipelines should be installed with a regulating valve.2. open the inlet control valve, so that water into the pump, in order to keep the cavity filled with liquid (otherwise it will damage the seal), close the outlet valve.3. turn on the power and make sure the correct turn.4. make sure the pump starts and runs after turning.5. adjust the opening of the outlet valve so that the pump runs near the design point, depending on the rated flow and lift of the pump. [for this reason, it is better to place a pressure gauge near the outlet flange). Note: this pump is strictly prohibited to run without water, so as not to damage the seal.

Q:What are the conditions required for hydraulic pumps to complete oil absorption and compression?: There must be one or more sealing volumes, and the volume of work is variable;
