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:How to maintain and repair the booster pump of pipeline pump?
I. installationAssembly and disassembly1. scrub all the spare parts to be cleaned.2. mechanical seals are installed on the main shaft of the motor, and a small amount of clean turbine oil or 20 oil is added to the surface of the mechanical seal.
Q:How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?
Water ring vacuum pump is divided into many types, different sizes, different types, so water is different. As for how much water the no fixed amount, but to ensure that the water temperature is in 25 degrees, not more than 35 degrees can be.
Q:How do vacuum pumps and pumps work together?
The role of the check valve:"[the water pump impeller is not closed" refers to the pump suction pump before the water without water inlet pipe and water outlet pipe gas should be connected] is a connector, a connector, still can make the level surface, in order to prevent the water flow along the pipe, until it reaches the level of the flush, then increased check valve.
Q:What are the internal losses in centrifugal pumps? How did they come about?
Volume loss: loss due to leakage;3. mechanical loss
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 is the principle of a turbopump?
Turbine [turbine] is a machine that converts the energy contained in a fluid medium into mechanical work, also called a turbine. Turbine is the transliteration of English turbine, derived from the Latin word "turbo", meaning "rotating object".
Q:What happens when a centrifugal pump is selected?
Centrifugal pumps are too big to measure.There is a reason why the centrifugal pump does not measure up:The pump inlet pipe blockage, leakage.The pump inlet pressure is too low.
Q:What kind of motor does the hydraulic pump need?
Calculation of actual oil pump power:First count the flow: Q=dn L / minD displacement / revN RPM / minThen calculate the actual power: N=QP/ (60K) kwQ flow L / minP MPa MPaK total efficiency (usually 0.85)I do not know what the landlord said, 2.5L is the displacement or flow at the end, the concept must not be confused
Q:Types and differences of pumps
Classification and working principle of pump by structureClassification of pumpsInvolved pump standard product types are also very much, a centrifugal pump, metering pump, screw pump, reciprocating pump, hydraulic pump, submersible pump, oil pump, water pump, pressure test pump, vortex pump, cryogenic pump, vacuum pump, roots pump, molecular pump, gear pump, mud pump, corrosion-resistant pump deep well pump, water pump, mixed flow pump, axial flow pump, boiler feedwater pump, liquid pump, injection pump, chemical pump, pump plugging and no leakage pump, plastic pump, fire pump and so on, there are many. Its name is divided according to some conventional classification methods such as pump vane pump volume, pump etc., some are divided by purpose such as sewage pump, pump and other health, some names are more random as diffusion pump, liquid nitrogen pump. As long as the production of this product, with standard requirements, through a certain application and approval procedures may produce a new The standard, but sometimes the content also has a repeated cross, quite. The domestic and foreign standards, the domestic standard is more than the number of foreign standards. In general, such as centrifugal pumps are widely used, the production history of the pump more standard (total standard centrifugal pump up to more than 100). As new standard pump leakage pump this rapid development is relatively small. This paper introduces the structure and working principle of the pump according to the classification of the
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.
