Advantage:

Comply with requirements of Standard EN 733 (DIN 24255)

High efficient and energy saving

Wide operation range

Compact structure

Wide application range

 

Back Pull-out Facility

All pumps incorporate the “back pull out” facility allowing the remove of the complete rotating element without disturbing the pipework. This features enables quick and simple maintenance to take place.

 

Interchangeability

Many of the components are interchangeable, this features resulting in a reduction in spares requirements, and an initial cost saving.

 

Excellent Bearing Housing Design

Incorporated with lifting eye to simplify removal of the rotating element during maintenance, “safe guards” are installed to prevent rotating shaft from human reach while in operation.

Main materials

Volute casing: Cast iron

Pump Cover: Cast Iron

Shaft: Carbon Steel or stainless steel

Impeller: Cast iron or Bronze or Stainless steel

Shaft seal: Gland packing seal or Mechanical Seal

Q:What are the categories of pumps?
Did you say the pump voltage is 220 or 380?
Q:What is LG water pump?
The LG in the LG pump should be a brand, without much practical significance.
Q:A direct type pump model with the coupling type, what is the difference?
This you can Baidu ah, otherwise it is not professional staff, it is estimated that will not be too clear
Q:What is the function of boiler feed pump, condensate pump, vacuum pump and low drain pump in operation?
The feed pump is a pump for supplying water to the boiler and maintaining the water level of the boiler. The condensate pump provides water to the deaerator after condensing the turbine and provides water for some condensate users. Vacuum pump is to maintain the vacuum of the pump, the pump is to lower the drain in a timely manner to the next level of low pump
Q:Why does the pump head decrease when the pump flow rate increases?
When the power increases to a certain extent, can not be increased, so when the flow increases, the head can only be reduced
Q:How much is the flow rate of fire hydrant and spray shared water pump?
Fire fire water is superimposed, at the minimum, the lowest 5L/S automatic spraying fire hydrant, light danger level 13.9L/S, the least is 18.9L/S, but the data is useless, the data are not spraying fire hydrant, concrete analysis of high-rise buildings like the dangerous level according to the calculation, the general design, the concrete building needs the high-rise building minimum 20L/S, automatic spraying dangerous level according to the general 30L/S, 50L/S need to flow
Q:How to identify the motor series of pumps
Look at the speed, see the modelFor example, the actual 1430r/min synchronous speed is 1500 rpm, the speed formula: speed = time (60 seconds) * frequency (50HZ) divided by the number of pole pairs one pole of 2 pole, which can be calculated 3000 83019 1500=2 on pole or 4 pole motor.See model is more straightforward: for example motor model is Y 132 M- 4Y, three-phase asynchronous motor, the three-phase asynchronous motor product name: YR for winding type asynchronous motor; YB explosion-proof induction motor; YQ high starting torque of asynchronous motor.  132, a high center (mm)M code, frame length4, the number of polesFrom the motor nameplate marked, you can see that the motor is 2, model FW12-2, speed 2840
Q:Ask the principle of fire truck and pump adapter
The water injected into the water pump is the water on the fire engine, and the fire engine is supplied by the city fire hydrant.
Q:What are the commonly used tools for repairing water pumps?
The most basic tools: a multimeter only about 20 yuan, 6 - 19 wrench a set of about 20 yuan, 200MM, 600MM adjustable wrench for each one of about 40 yuan, a cross, a screw knife is about 6 yuan, about 100 yuan a Lamar, claw hammer, hammer, rubber hammer, flat shovel each one about 40 yuan, a vise, pliers, diagonal pliers pliers, 8 words for each one of about 30 yuan, tweezers, knives, pressing line plate each one of about 15 yuan, 60W electric iron to about 25 yuan, a box, a soldering flux of about 15 yuan, or lamp the incandescent lamp, the crowbar can use local materials, needle, slide board with bamboo made with wood or self winding plate with the line of 80 yuan purchase mode. Insulating paint, asbestos pipe and tie band. Commonly used spare parts: enameled wire, water resistant lines, insulating paper, lead wires, various types of seals, bearings, impellers, lithium based grease, etc..
Q:Three phase water pump rated power 4000W, is three-phase working water pump, the voltage is 380V, how to find the three-phase pump current, and calculation of public
Three phase water pump motor rated power 4000W is the output shaft power, divided by the motor efficiency (general 85%) is the input power, which is often mistaken. The electric power is =4000/0.85=4706WRated current = electric power /1.732x, rated voltage x, power factor =4706/1.732x380x0.8=8.94A (assuming power factor 0.8).The above three answers are all wrong.
