Features

1.Very high safety of operation. Mechanical actuate diaphragm. Changeable eccentric drive

2.Power off seal,no leakage,with security delivery device,simple maintance

3.It can transport high-viscosity mediums, corrosive liquid and dangerous chemical goods.

4.The flow can be controlled via adjusting the length of stroke or the motor frequency.

5.The diaghragm is made from multilayer complex structure to promote the life span, the first layer is Teflon anti-acid diaphragm, the second is EPDM stretch rubber, the third is 3.00 mm thick SUS304 that supporting the iron corn. The fourth is also the EPDM stretch rubber to cover all of the body.

Purpose

Widely used in petroleum, chemical industry, electric power, metallurgy, mining, shipbuilding,light industry, agriculture, national defense department and etc.

Q: If the suction pump does not have enough suction range, you need to add a vacuum pump to increase the suction stroke. How do you install the suction pipe of the vacuum pump? Water pump impeller is not closed, it is normal that the vacuum pump is unable to pump suction pipe to a vacuum, is it because the water pump outlet pipe connected to the role of the check valve? But the water pump, outlet pipe, check valve sealing performance can achieve the function of non leakage?: Vacuum suction principle of self suction pump:Assuming that the pump connected with the water inlet of a sealed container, the container has plenty of water, since the start of a water pump, water is thrown out of the water impeller pump body, water inlet seal vessel due to the extraction of water to form a vacuum cavity, this assumption will be connected to vacuum cavity and exposed to atmospheric conditions of water, water at atmospheric pressure under the effect of entry into the vacuum chamber".

Q: What does "anti pump" mean in pump operation?: Function: anti pump effect when used for pumping concrete pumping occurs overpressure, the pumping pressure is above 25MPA, the concrete conveying pipe out of ash, can be understood as the precursor of pipe blockage, at this time should immediately use the anti pump, the concrete from the conveying pipe in the suction into the hopper, thus preventing plugging happen

Q: What is cavitation, centrifugal pump cavitation phenomenon how to solve?: Centrifugal pump cavitation phenomenon how to solve?:Measures to improve cavitation resistance of centrifugal pumps(1) improve the design of the suction port of the centrifugal pump to the impeller. Increase flow area; the radius of curvature increases the impeller cover inlet section, reduce the flow accelerated sharply with pressure; reduce the thickness of the blade, and the blade inlet rounded, close to the streamline, can also reduce the acceleration and pressure flow around the blade head portion of the impeller and the blade inlet part; improve surface finish in order to reduce the resistance loss; the blade inlet edge extends to the impeller inlet, the liquid flow in advance to accept work pressure, improve.

Q: Water pump outlet valve sequence: To reduce the impact of vibration, noise and vibration on the valve, the soft connection is best at the pump outlet.The check valve is sometimes checked, so it is placed in front of the outlet valve so that the water can be checked out. I think the order should be: pump outlet, soft connection, check valve, gate valve (butterfly valve)

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's the difference between non negative pressure and variable frequency water pump?: Re pressure to a given pressure pressure zone water supply, than frequency conversion water pump energy savingFrom a health perspective, a water tank variable frequency water pump, water tank and the atmosphere, easy occurrence of water pollution two, no negative pressure equipment without negative pressure tank and pump and valve fittings etc., no water tank, the whole process of water supply of water is completed in a closed system, with air contact to avoid two pollution problems water supply.From the management point of view, no negative pressure is fully automatic intelligent operation, reduce management costs, no water tank, reducing the trouble of tank cleaning. No negative pressure is the upgrading of variable frequency water pump products

Q: Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?: Pigment pressure is less than 0.4mpa,About 0.3. Go up.As the pump diaphragm is in the middle of a connecting rod, equivalent to the cylinder cavity, the pressure will be reduced; and because of the loss of pigment tube pressure will be reduced.

Q: What are the problems that should be paid attention to when using vacuum pumps?: (1) check the vacuum pump line and the joint site regularly to see if there is any looseness. Turn the vacuum pump by hand and see if the vacuum pump is flexible.(2) add lubricating oil to the bearing body, observe the oil level at the center line of the oil mark, and the lubricant shall be replaced or supplemented in time.(3) plug screw vacuum pump of the water screw, filling water (or lead paste). (4) turn off the gate valve of the water outlet pipe and the outlet pressure gauge and the vacuum gauge. (5) point motor, and see if motor steering is correct.(6) start the motor. When the vacuum pump is in normal operation, open the outlet pressure gauge and the inlet vacuum pump. As soon as the proper pressure is shown, the gate valve is gradually opened, and the motor load is checked.

Q: How many square cables does the submersible pump for 7.5KW need?: According to current I=13A, it is estimated that the cable is less than 10 square meters, so the cable cross section can be calculated at the ampacity of 5A per square meter. The square section of the cable is =13/5=2.6 square. According to the specifications series, optional 2.5 square aluminum cables. When the cable is longer, it is safer to choose 4 square aluminum cables.

Q: What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?: A single-stage pump is a pump with only one impeller. 2, a multistage pump is a pump with two or more impellers. The multistage pump can increase the pressure and lift the head higher. Level 1 means a booster impeller.
