SZ SERIES SINGLE-STAGE WATER-RING VACUUM PUMPS
1. Working principle
The impeller is eccentricity installed on the pump body. It rotates to make eccentricity water ring with impeller. The water is fully filling into body and impeller, continually cycling and reciprocating to change water volume between impeller. With air inlet and outlet co-function, it finishes air-sucking, compressing and exhausting.
2. Feature & Application
SZ Vacuum pump for extruder
SZ Vacuum pump is used to draw air bubble and wet air in melting material and all of low molecule matter such as solvent, mixture, reactant and residue etc. The purpose is to get the best pipe quality:
Smooth surface.
Strengthen elasticity.
Improve isolation performance.
Reduce air release in following process.
It is quite an important process to remove air efficiently in material plasticizing. It's to remove air bubble and wet air from melting plastics conveniently in extruding process. It's better remove air from the single-screw extruder. And it's necessary for double-screw extruder.
SZ Vacuum pump for profile extrusion
SZ Vacuum pump which widely used in plastic forming process, improves not only but also working environment. It keeps operator safe.
It exhausts air in extruding process. It ensures accurate alignment between profile section and mould.
SZ Vacuum pump for forming machine
SZ Vacuum pump acts an important role to ensure profile dimension precision.
Soft profile material is gradually cool down and becomes rigid. In each process, different vacuum degree can ensure profile stick closely on inner surface of mould properly. At the same time it ensures the dimension precision after forming.
SZ vacuum pump can keep a stable vacuum degree during running. It draws leaking air too. SZ-3A model can also draw the cooling water being absorbed.
With above advantages SZ vacuum pump is widely used in plastic forming. It's wisdom to choose SZ vacuum pump.
3. Notes
1).SZ-3A Vacuum pump is one kind super-silent pump which based on model SZ-3. It is newly developed by selecting design parameter specially and adopting advanced structure according to customer requirement in plastic industry area. It is little flow loss, low noise, weak shaking and big storage of motor power. Therefore it can run in safe for long time when there's water at inlet.
2).It's special motor for SZ series vacuum pump, not normal Y type motor in the market. Please make special order to our company if you want to change your motor.

5. FAQ
1 Can your pumps mount Eff.1 motors
Currently, only on request though this will shortly be a CNBM standard.
2 Are your pumps protected against dry running?
No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.
- Q: We just replaced the motor on our water pump that burnt out but we are still getting no water pressure. My father in law did a lot of test stuff on it he thinks it's the foot valve. Well I've been trying to call every where get quotes but NOT 1 of the places I called is answering their phone for some reason. So how much dose it usually run to have someone come fix your foot valve so I have an idea to tell my husband?
- A very good foot valve will cost about $20 then it will be the cost of a service call, here we charge about $70 but depending on where you live, how deep the valve is and where its located the price maybe different, and the cost maybe more on a weekend too. Giving quotes for this is not really profitable for service companies, so if you are not prepared to do it yourself then you will have to pay the service call rate. A good reputable company will arrive at your home and give you an approximation on what it will cost, but remember once you call them there you will probably have to pay the service call rate, if you are running tight on money call around and ask the rates but remember that this is a weekend and most companies will be running a small crew and might take time to answer your call. The other option is since you have changed the pump yourself why not just change the foot valve your self? Have you primed the pump after replacement? To replace the valve the pipe that runs to the bottom of your well must be pulled up and the valve is on the bottom of it, its a simple matter of removing the old one and replacing with new the big job is usally the pulling up of the pipe.
- Q: i want to make this for a physics project for school. i found a video on how to make it, but i dont understand the physics behind. i have to make a model and a poster explaining the physics. i dont understand what to put on the poster so could someone help me with which physics principles this project would go with?
- It isn't practical to give a detailed description here. This is a positive displacement pump. The pump chamber is sealed so that as the piston is moved up the volume within the chamber increases. Water is pushed into this chamber by the outside air pressure. If the pump is located too far above the water source then the air pressure is not sufficient and you will produce a vacuum inside but the water still will not flow. When the pump is pushed down the water flows out. Now the one way valves are critical. We don't want the water to flow back the way it came and we don't want the water that we have already pumped to flow back into the pump. So a one way valve on the inlet will permit water to flow into the pump but not out of it. And a one way valve on the outlet will permit water to flow OUT of the pump but not into it. So with each stroke you a) reduce the pressure in the pump. b) water is forced from the inlet, past its one way valve and then into the pump. c) the pump is pushed down increasing the pressure in the pump. d) water flows out of the pump through the other one way valve and on to the output.
- Q: TDH what units are present in the pump parameters?
- Answer: TDH stands for single pole double suction horizontal chemical process pump, suitable for conveying clean or containing micro solid particles of ultra low temperature or high temperature liquid medium, is also particularly suitable for conveying strong corrosive medium. All facilities for horizontal installation are available.Mainly used:Petroleum smelting plant, petroleum conveying equipment and pump used in petroleum deep processing devicePump for coal chemical processPumps for water and desalination systemsPumps for fuel coal fired power generation equipmentSewage treatment and environmental protection pumpStructure characteristics:Pump in the horizontal opening, suction and discharge pipeline is located in the lower half of the pump body. The disassembly and replacement of the wearing parts and the replacement of the rotor parts can be performed without disassembly of the pipe.Double suction impeller, high efficiency, good cavitation performance, axial force is basically balanced.Rigid axle shaft and bearing, double end support, small deflection, small vibration, low noise, oil lubrication of rolling bearings with oil ring, constant level oiler automatic control level, and can get automatic compensation, radial thrust ball bearings back-to-back bear residual axial force.The sealing ring of the shell is provided with a stop and a step, and is arranged on the pump body and the pump cover, so that the assembly and disassembly are convenient.
- Q: I have a 2000 Dodge Stratus and recently had the coolant drained (not quot;flushedquot;, as the mechanic wanted to charge $125 extra for that). Prior to that time I never had a single coolant leak, but since then, I've had the coolant leak out slowly over about a 2 week period of normal stop go traffic. Now the mechanic is saying the water pump is leaking, and that's going to be another $600+ more to fix (over 5 hrs of labor), which I really don't have the money for right now.So two questions.. 1) what could've happened to cause the water pump to suddenly start leaking only after the coolant was drained, when it was fine before that? and 2) should I try using a quot;Radiator Stop Leakproduct? I know people say they can plug up the whole radiator, but if that were the case 100% of the time, you'd think these products would've been made illegal a long time ago.SO realistically what are the chances of it doing more harm than good? I still plan on getting the water pump replaced, it'll just have to be awhile.
- the pump will quickly wear out if its leaking, and on those stratus's the water pump is run on the timing belt, which makes it a long and expensive job to replace. I wouldn't use the stop leak, just carry around a few gallons of water and keep the coolant topped up. keep an eye on your temperature gauge while your driving.
- Q: my water pump went bad on my 1997 chevy cavalier, causing it to leak all the coolant it had in the system. i put water in it til i could get new water pump. changed out water pump. attempted getting air out of system. put more concentrated coolant in system than i did water. bad guessing on my part. ran car around block 5 times. it was fine. this morning on the way to work, it started overheating again. my thoughts : more air in system that's not coming out? thermostat REALLY went bad at same time as water pump???? overheating all because of a little too much coolant??? for some crazy reason, my system needs to be suddenly flushed? Your thoughts? one last thing, the car has always ran perfectly normal temp til water pump went bad.
- Check your radiator,check your radiator fan to see if it works! Sometimes they go bad or their sensor won't work anymore and the car is overheating the sensor doesn't pick that up and the fan won't start! That's make the car overheating!
- Q: For what reasons can water pump in car break? Thanks
- The 2.7 and it's water pump are simply a problem waiting to happen. Poor design.
- Q: I would like to use water from the lake to water my lawn. My lawn is about 100 feet up hill from lake. Just want something I can attach a garden hose to. what type of pump and horsepower do I need.
- Not less than 1.0 horse power pump is needed to lift water from 100 ft down. But, if you want some more power, you need not get more than 1.5 H.P. in any case.
- Q: I have a toyota supra 83 Mechanic said water pump is leaking into engine causing white smoke. He said that hell have to replace water pump nd all gaskets estimated about 500+$ is this accurate? Also water resevoir mysteriously loses water can it be a symptom?
- Sounds fair to me. if it's a 7mgte have him do the timing belt while he has it all apart.
- Q: For a basement water pump that controls the toilet, shower and sink--- does it always have to stay plugged in and running??? I heard it make a weird noise and shut it off immediately.. Any help appreciated!!!
- Most of the time when you use water a large amount the pump will come but should shut off after a reasonable amount of time. When the set pressure is achieved it will shut off. And when the pressure drops it will turn on and the pressure will drop when using water.
- Q: the car over heats and I hear the antifreeze boiling and it also leaks a small amount of antifreeze amechanic told me i need a thermostat and a new water pump just looking for second opinion.
- First check the water pump for leaks and wiggle the shaft to check for bearing wear. If either is present replace the pump along with the thermostat. If not only replace the thermostat. If the radiator is boiling over after a short drive, the thermostat needs replacing.
