SFL series pumps are equipped with impellers and guide vanes made from stainless steel plates through advanced stamping, welding and forming technology, with beautiful appearance and reliable performance, other main components and parts are made from stainless steel.

This series centrifugal pump has most complete varieties, most wide flow and lift range in the domestic and foreign similar products.

Low Noise Multistage Centrifugal Pump Blackone:

  1. Reliable performance: each kind of product can reach design index and run in high efficiency. Welcome users to make own demands in performance parameters.

  2. High efficiency and energy saving: special structure, reasonable runner design and matching gap, the smooth flow part ensures low frication, low resistance, low loss and high efficiency.

  3. Small volume and light weight: the impeller and guide vane etc. main components are stamped and formed by stainless steel plate, reducing volume and weight.

  4. Low noise: select and use special location structure, processing technology and noise reducing measures to greatly reduce noise.

  5. Convenient installation and maintenance: the inlet and outlet are on the same axial line, which is convenient for direct connection and disassembly of the whole pump and water supply pipeline.

  6. Clean environment: it is equipped with exhaust valve and water injecting valve with rubber pipe joint, which ensures the cleanness of environment.

  7. Beautiful design: the products is fused into the shape, proportion and color etc. aesthetic design, and adopts special outer sleeve processing technology and high standard quality 3.

  8. Water purification function: the electronic physical purification equipment is adopted to achieve sterilization and scale prevention automatically during pump running, which not only purify water, but also ensure the completeness of other water supply equipments and expand their lifespan.

Q:What are the categories of pumps?
First, select the pump to meet the requirements of the headThe so-called head refers to the required lift, and not lift the water height, clear this point, the choice of water pumps is particularly important. Pump lift is about 1.15 to 1.20 times the height of lifting water. If the vertical height of a water source to the water is 20 meters, the required lift is about 23~24 meters. When selecting a pump, the pump head should be close to the required head, and the general deviation is not more than 20%. In this case, the efficiency of the pump is the highest, and it is more energy efficient, and the use will be more economical. If the lift on the nameplate is much smaller than the required lift, the pump can not meet the needs of users, even if the water can be pumped, the water is also very poor. But in turn, the high lift pump for low head, there will be heavy traffic, resulting in motor overload, if long time operation, the motor temperature, the winding insulation layer will gradually aging, and even burning motor.Two, select the appropriate flow pumpWater pump flow, that is, the amount of water is generally not too large election, otherwise it will increase the cost of water pumps. Should be selected as needed, such as the use of the user's family self-priming pump, the flow should be chosen as small as possible; if users use the submersible pump irrigation, you can properly select a larger flow.
Q:What's the submersible pump?
Submersible pump is a pump directly on the water inside the pump, eliminating the water inlet pipe, eliminating the trouble of ordinary water, is very convenient, just a pool, pool, bucket, water tank water level is shallow to be able to work, meet your requirements of pumping drainage. Not afraid of water, because it is placed in the water itself to cool themselves, you can use for a long time. The amount of water pumped and the height of the water now basically meets the needs of a small amount of individual and a large number of factories. This is the submersible pump, the water pump in the water. You can see.
Q:How to remotely control submersible pumps?
Yes, the pump remote control has been done by many manufacturers, and the program is very mature, Tangshan is one of them, you can consult yourself.
Q:What is the function of a submersible pump?
Submersible pump motor and pump is directly connected with the water pump body into the water to work, it is suitable for the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects: mainly used for irrigation and plateau in the drinking water, but also for the city, factories, railways, mining and construction site the use of water supply and drainage.Characteristics of submersible pumps for well1 、 motor, water pump, submerged operation, safe and reliable.2, the well pipe and pump water pipe without special requirements (i.e.: steel tube wells, tube wells, Doi ash can be used).3, installation, use and maintenance of convenient, simple, small footprint, do not need to build pumping stations.The structure is simple, and the raw materials are saved.4, submersible pump conditions are appropriate, properly managed, and has a direct relationship with the service life.
Q:Why should the water pump be opened in time after the pump is started?
There are many kinds of water pumps in power plants! Single-stage centrifugal pumps generally do not open in time, with the valve opening current increased! Multi stage centrifugal pump should be opened in time, otherwise it will lead to fever due to compression of liquid! With the valve opening, the current will increase! Single stage axial flow pump usually open the valve open, with the valve opening, current changes little or fall!
Q:Is the pump lift horizontal or vertical?
A vertical, vertical lift is one meter (see environment), usually 5~10 times the horizontal distance
Q:What is called soft start of water pump?
Soft start is a form of electronic control, mainly through the soft drive to achieve. Principle: the former contactor is directly started as contactor, first pull in, and the device is started by soft driving. Soft start device start smoothly, starting current is small, control system life is long. Soft start is now in widespread use. But the use of high-power equipment is less, the general current is less than 120A.
Q:How should the water pump breaker be selected?
If it is a single-phase motor, rated current is 75A; three is about 30A; the contactor should be 1.1-1.5 times the rated current of the motor protection type selection of circuit breaker, circuit breaker: RMM1-100/33002 or 50A motor comprehensive protector, the price is not expensive.The circuit breaker (English Name: circuit-breaker circuit, breaker) refers to the closing, carrying and breaking current conditions and normal circuit switch device, load and breaking current loop abnormal conditions within the stipulated time. The circuit breaker is divided into high voltage circuit breaker and low voltage circuit breaker according to its range of use. The demarcation line of high and low voltage is fuzzy. Generally, more than 3kV is called high-voltage equipment.The circuit breaker can be used to distribute electricity, not frequently start asynchronous motors, the protection of the power line and a motor, can automatically cut off the circuit when they occur serious overload or short circuit and under voltage fault combination, its function is equivalent to the fuse switch and less thermal relay etc.. Moreover, after breaking the fault current, there is no need to change the components. At present, it has been widely used.Distribution is an extremely important link in the generation, transportation and use of electricity. Distribution systems include transformers and various high and low voltage electrical equipment. Low-voltage circuit breakers are a wide range of electrical equipment.
Q:What is the difference between a fire pump and a living water pump?
1, fire pump is actually divided into many kinds, such as car, fire hydrant system, spray system, etc., life pump is also, the distinction between them is sometimes difficult to tell the exact. Simply put, the fire pump in its design must meet the corresponding fire requirements, such as pressure, speed, work adaptability, etc., specific requirements can be found in "national standard GB 6245-2006, fire pump Fire, pumps""2, the same function of fire water pump, its price is relatively stable. I personally feel that we must find more manufacturers to understand the reasons for the price difference, and then make a choice.
Q:The problem of single phase pumps
The capacitor is broken. Change it.
