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: Troubleshooting of diaphragm pump: The troubleshooting guide for diaphragm pumps, when encountered in one or more of the following situations, this information can be used as a guide to help you develop maintenance measures.As shown below, some of the abnormal operating conditions described in this guide are: A) fast circulation / low flow B) no cycle / slow cycle / irregular cycle C) leakage D) noise E) component rupture

Q: How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?: For example: water storage is relatively small, it needs to reduce the temperature of the heat exchanger. If the tank is relatively large, it does not need cooling water circulation pump again when the temperature is very low, there is no need to heat exchanger. So you need to ask how much water this is not OK.In a soda separator problem:

Q: What are the characteristics of a pipe shield pump?: According to the transmission of liquid temperature, pressure, viscosity and particle level have different requirements, the pump can be divided into the following types: first, the basic type (standard type) transport medium temperature does not exceed 120 degrees, the head of not more than 100m, the pump other types are variations on the basic type and improved.

Q: What does "anti pump" mean in pump operation?: The working process of the main oil cylinder pushing back and forth against the pump when the S valve (C valve or valve or gate valve skirt) reverse swing, so the piston suction concrete cylinder is in the ash conveying pipe is exactly opposite is the pump suction pump (hopper is concrete and push into the hopper, the desizing)

Q: What are the starting and stopping procedures for centrifugal pumps?: Before using the centrifugal pump, the operation instructions of the centrifugal pump shall be read carefully and the specific operation procedures shall be understood so as to make proper use of the centrifugal pump products. The first step is the operation of centrifugal pump inlet valve of centrifugal pump centrifugal pump for all open cavity filled with liquid, close the outlet valve, start the motor, the motor speed is normal, can gradually open the outlet valve, to adjust to the desired condition. Pay attention to self suction centrifugal pump starts to open the exhaust valve, outlet valve should be opened quickly in the normal operation of the motor, to prevent air inlet pipe off caused by cavitation phenomenon produces centrifugal pump, centrifugal pump vibration phenomenon leads to noise of the smoke is not on the water.

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?: Installation method of hydraulic pump(1) according to the technological requirements and the cavitation conditions of the pump, the installation height check and the civil engineering of the foundation are carried out.(2) prepare a series of flat washers and wedge gaskets of different thickness before installation.(3) according to the characteristics of the pump conveying medium, determine the material of the gasket at the connection and process the gasket.

Q: Rules for operation of centrifugal pumps: Working principle and process flowWorking principle: when the drive motor with high-speed rotating impeller, full of fluid in the pump body under the action of centrifugal force, was thrown from the impeller center to the outer edge of the impeller, in this process, the fluid energy, improve the pressure can, at the same time also increases the energy flow rate increase. The liquid from entering the pump impeller shell, the liquid flow gradually widened, the liquid velocity decreased gradually, which will be part of the kinetic energy into pressure energy, which further improves the static pressure of liquid, and liquid with high pressure in pressure pipeline. When the liquid from the leaves out when the impeller center creates pressure and low pressure than the out plane is big, under pressure drive, liquid is continuously from the center of the impeller suction, with the pressure of continuous discharge.

Q: Why does the centrifugal pump start and close first when the outlet valve is closed?: The operation rules of centrifugal pump strictly required to close the outlet valve before the shutdown, boot and then slowly open the outlet valve, regulating pipeline pressure and current range. The reason is: the centrifugal pump in the startup process in order to avoid large starting current caused by electrical faults, such as circuit breaker tripping,

Q: Suction stroke and lift of water pump: For example: there is a kind of water pump, the model is called "BSP" series, the volume is not large, but the nominal suction process can be 4 meters, it can not add water to 4 meters, it is considered to be relatively high in the micro pumpIn micro pumps, not all pumps have self-priming capacity ("suction stroke")Some centrifugal pumps there is no self-priming ability to use must first do add water. Although some micro pump with self absorption capacity, but "suction" are often the subject of "and the water inlet pipe in all air, can smoke the vertical height of water gap, even only half not so. The pump selection, the absorption process is a relatively important parameter.

Q: How accurate is the metering pump?: In addition, when the oil supply is too large or the pipeline pressure rises unexpectedly, the volume of the liquid in the hydraulic chamber can be changed, thereby affecting the stability of the flow and reducing the metering accuracy of the pump. In order to solve the problem of how to stabilize the measurement accuracy of metering pump metering pump flow, how stable, the three valve device. The so-called actual refers to the combination of three functions including compensation, discharge and safety protection device or device supporting the hydraulic chamber, according to its action principle is different, is divided into automatic compensation and forced compensation two three valve device.
