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:Harm of air pump and pump
Centrifugal pump situationEmpty pump is divided into two kinds, if there is no liquid, then it will cause the mechanical seal of the pump to overheat, wear and even die
Q:What is the Rhodes pump?
Best answerRoots vacuum pump (referred to as: Roots pump) refers to the pump is equipped with two opposite direction of synchronous rotation of the leaf rotor, rotor, rotor and pump housing between the walls of a small gap and no contact with a variable capacity vacuum pump.Roots vacuum pumps have been tested for long time in the fields of petroleum, chemical, plastic, pesticide, steam turbine rotor dynamic balance and aerospace simulation, so it should be popularized and applied in china. It is also widely used in petroleum, chemical, metallurgical, textile and other industries. Vacuum pump fittings are used for noise control of vacuum pumps, vacuum pump silencers.
Q:What is the pumping property of concrete?
Pumpable concrete slump is generally greater than 160mm, the mortar content is too low, the maximum aggregate size of not more than 1/3 of the diameter of the pump pipe, sending process segregation, plugging in the pump.
Q:Why adjust the centrifugal pump outlet valve can adjust the flow?
This method can be used to regulate flow. The advantage is that it is simple and easy to use and the disadvantage is that the throttle consumes energy
Q:What is the name of the day pump and ground pump? Specific introduction
People often say "day pump" actually refers to the boom pump, it also has many other name, such as pump, boom pump, concrete pump, concrete pump truck, these words are "day pump".Ground pump, in fact, refers to the pump drag pump. Therefore, to understand the difference between day pump and ground pump is to understand the difference between the boom pump and the tow pump
Q:What are the ways of hydraulic pumps?
Check valves, such as single piston pumps, three piston pumps, etc.;The port of the valve arrangement, such as the radial piston pump.
Q:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
Have to know the ratio, pneumatic pump, if high pressure, you can have 2:1,3:1
Q:Pump unloading in hydraulic transmission,
Unloading water, from the literal interpretation is along the pump, leakage of water seal through the head, the water with certain pressure (even with relief effect seal). The water as the working quality is asked to be recycled, now the design of some use it as a water seal, and others by direct recovery, but eventually recovered.
Q:What are the main performance parameters of the pump?
The amount of liquid supplied by a pump in unit time. Volume flow Q, unit m3 / s. There is mass flow G, unit is kg / s.
Q:What is the pump, how to classify, mainly used in where?
Classification of pumpsAccording to the principle of division:1. displacement pumpDepending on the movement of the work parts, the volume of the work increases periodically and reduces the suction and discharge of the liquid, and the pressure of the liquid increases directly by the extrusion of the working partsAccording to the different movement of moving parts, it can be divided into two types: reciprocating pump and rotary pumpAccording to the structure of the moving parts are different: piston pump and piston pump; there are gear pumps, screw pumps, vane pumps and water ring pump
