Product Description:

FEATURES:

Vertical Multistage grundfos water Pump is the latest model with the features of energy-saving and less space demand, easy to install and has stable performances.

 

1. With its 304 stainless steel shell and wear-resistant axle seal, there is no leakage and it can live long service life.

 

2. With hydraulic equilibrium to balance the axial force, the pump can run more smoothly, less noise, which can be easily installed in same level pipelines, enjoying better installation conditions than DL model.

 

3. With these features, GDL Pump can easily meet the needs and requirements for water supply and drain foe high building, deep well and firefighting equipments.

Q:Which nuclear submarines use the shaftless pump technology?
Shaftless pumping technology and Simulation of shark skin technology are all the next generation of submarine propulsion technology. At present, there is no submarine in the world.
Q:What is the pumping property of concrete?
Under a certain pump pressure, the farther or higher the concrete can deliver, the lower the probability of clogging, the better the concrete pumping performance.
Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
That is impossible. The suction height of the pump is caused by the centrifugal force of the vacuum. The water is sucked into the vacuum
Q:What does the impeller on the centrifugal pump mean by the first cutting?
There are 2 situations, first, for example, a XXXX-160 type pump head 32, flow 100, motor 15kW, according to the model we need to cut a become head 28, flow rate of 88, this time, in addition to cutting the impeller, the pump or the original pump motor, became 11kW this is, re designed a new model, namely XXXX-160A, but most structural components did not change. In the same way, we want to design a XXXX-160B that makes the head 24 and the flow rate 80, then we just need to cut the impeller again and match the smaller (7.5kW) motor (the motor bracket needs to be redesigned). In general, multiple cutting impellers are designed to expand and enrich the model. Second, the actual use, if you think the flow head is too large, but also can be cut to make it smaller to adapt to practical applications. But the 2 and 3 cuts you ask are the first.
Q:How many millimeters is the diameter of the water outlet of the four inch pump?
Here is a 4 inch inch, not rural, 1 inches =25.4 mm, 4 inches is approximately 100mm, with DN100 pipeline.
Q:What are the parts of a pump? How do you classify it?I just want to know
According to the working principle can be divided into: centrifugal type and volume type centrifugal pump. By the centrifugal force of the impeller will accelerate the refrigerant, through to stay, so as to achieve the purpose of boosting; volume by changing the refrigerant in the flow volume to boost purpose.According to the media and installation conditions, water pump: centrifugal pump used: the impeller pump shaft, a curved blade on the impeller impeller outlet. The central entrance water vertically along the tangential direction of axial flow pump: high speed, large flow, low lift, mixed flow pump and centrifugal pump structure similar to that of the blade outlet angle is different, wide flow channel, close to the performance of axial flow pump displacement pump: safety valve must be opened before the start (metering pump, screw pump)
Q:What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.
Submersible pumpThe submersible pump is composed of a control cabinet, submersible cables, water pipes, submersible pumps and submersible motors.Submersible pump main application and scope of applicationIncluding mine rescue, construction, drainage, agricultural irrigation and drainage, industrial water recycling, urban and rural residents cited water supply, and even rescue, disaster relief and so on.Classification of submersible pumpsAs far as media is concerned, submersible pumps can be broadly divided into three categories: clean water submersible pumps, sewage submersible pumps, sea water submersible pumps (corrosive).
Q:What are the main performance parameters of hydraulic pumps?
Main performance parameters of hydraulic pump:1. Hydraulic pump pressureHydraulic pump operating pressure is the pump (or motor) in actual work output (or input) oil pressure, determined by the external load.Rated pressure refers to the maximum pressure under continuous running in accordance with the test standards under normal working conditions. The size of the pump is limited by the service life, and the service life of the pump (or motor) will be shorter than the design life if it exceeds the rated pressure. When the work pressure is greater than the rated pressure, it is called overload.
Q:What is the lift of diaphragm pump?
Tell you: diaphragm pump head is liquid through the pump energy obtained is called lift it, and flow and pump speed, a liquid density is generally 1 kg is 10 meters lift, horizontal pipeline 10 meters 1 meters lift, a 90 degree bend is 1 meters.
Q:How high can the pneumatic diaphragm pump be?
Diaphragm capacity, high temperature, pneumatic diaphragm pump ability, high temperatureMany users do not know how high the temperature resistant diaphragm pump, diaphragm pump either electric diaphragm pump or pneumatic diaphragm pump products it cannot do without diaphragm attachments, diaphragm materials mainly fluorine rubber, rubber, rubber, polyether road three EPDM, PTFE several, if not considering the gas temperature resistant diaphragm made of stainless steel. The temperature to 600 degrees of diaphragm pump diaphragm pump, but must use the diaphragm, so the diaphragm pump can Naiduo high temperature depends entirely on the diaphragm was affected by temperature, following to share various diaphragm pump diaphragm material and different material temperature choice diaphragm pump product right:
