Specifications

1.Submersion depth 5m
2.Head up to 35m
3.Flow rate up to 1800L/min
4.Passage of suspended solid up to 35mm

Range of Performance

Flow rate up to 1800L/min(108m3/h)
Head up to 35m


Application and Installation
They are recommended for draining dirty water and sewage in the domestic and civil sectors. Being equipped with a single-channel impeller, they are allowed to pump liquids containing suspended solid bodies with dimensions up to 35 mm and short fibres. They are ideal for pumping drainage water, sewage or waste water for a single dwelling, and for clearing surface or nuisance water. These pumps are outstanding in their reliability in fixed installations with automatic operation.

Q:What are the main performance parameters of the pump?
The main performance parameters of the pump are:The energy obtained by pumping a unit weight of liquid through a pump. In H, the unit is m.
Q:Roots pump and dry pumpRecently, the work involved in the vacuum pump, do not understand this, is a ads602 vacuum pump
The front stage pump to a certain pressure to start the roots pump, roots pump has advantages of is at the entrance of low pressure gas pumping speed is high, popular point is in high vacuum pumping speed is still relatively large. With the former pump can achieve different limit the vacuum is different.
Q:Does the control cabinet of the fire control pump need to be related to the fire control room?
The relationship is simple, the fire pump is pressurized water supply device, the control cabinet is the power supply for the fire pump, the regulator tank is to stabilize the pressure of the network management, reduce the pump frequently start device.
Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?
Rated flow refers to the flow under the rated speed and rated pressure input to the motor.Due to leakage loss, the actual flow of the input motor must be greater than its theoretical flow. Actual flow of motor (i.e. inlet flow) leakage flow = theoretical flow of the motor.
Q:What is the difference between centrifugal pump and self suction pump? Which is better?
In order to prevent the filling liquid into the pump shell because of gravity flow in the low groove, in the pump suction pipe at the entrance of a non-return valve (valve); if the location of the pump below the liquid level in the tank, then start without irrigation pump.Self-priming pump is a self-priming centrifugal pump, centrifugal pump is a kind of.Specific choice of a pump, depending on your specific parameters and conditions of use.
Q:What are the problems that should be paid attention to when using vacuum pumps?
What are the problems that should be paid attention to when using vacuum pumps?
Q:How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
For example, once you sprinkle water from the tank to the ground, one shot of water is 1000 milliliters, which is equivalent to displacement, once (pump turn) 1000 ml.,
Q:The function of centrifugal pump
4, bearings are set on the pump shaft supporting the pump shaft components, there are two kinds of rolling bearings and sliding bearings. Rolling bearings use butter as a lubricant, refueling should be appropriate, generally 2/3 ~ 3/4 of the volume is too much, will heat, too little, there is noise and fever! The plain bearings are made of transparent oil as a lubricant and fill up to the oil level. Too much oil will leak out along the pump shaft and float *, too little, the bearings will overheat and burn out, causing accidents! In the pump running process, bearing temperature is highest in 85 degrees, generally run at about 60 degrees, if higher, will find the reason (whether there is impurities, whether the oil is black, whether water) and timely processing!
Q:Is the centrifugal pump large or small?
Centrifugal pump, the smaller the better the cavitation.1, centrifugal pump cavitation less, anti cavitation performance is better, the pump cavitation is called the necessary cavitation margin or pump inlet dynamic pressure drop, the smaller the better. Generally speaking, the pump cavitation is the need for cavitation, the pump inlet pipe said effective cavitation margin, that is, the device cavitation margin. For a given pump, at a given speed and flow rate required NPSH is called pump necessary NPSH, also called NPSH, is required to achieve the performance parameters of the pump cavitation, the internal flow and the centrifugal pump is composed of pump head itself, its physical meaning is that liquid drop in pump inlet pressure part degree, is to guarantee the pump cavitation does not occur, with surplus energy exceeds the vaporization pressure head at the inlet of the pump unit weight of liquid. The cavitation must be independent of the device parameters. It is only related to the parameters of the inlet of the pump. These parameters are determined by the geometric parameters at a given speed and flow.
Q:The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?
Difference:The installation position is different: one can discharge water, one is on the ground.The work principle is different: the principle of submersible pump is similar to the electric fan, centrifugal pump through centrifugal force to make the water throw out. According to the principle of centrifugal force design,
