Product Description:

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:how does a water pump work?
Water pump works by suction and lifting up the water to a desired level. The mechanism of pump to increase the hydraulic height/level of fluid. Example : The pump will pump and lift water from a 25 feet deep well and carry it up to fill a water tank placed on a 30 feet high structure.
Q:Pump head is too high what's the impact?
After the determination of the pump type, such as the actual pump lift is too high, it will not only result in lower efficiency of the pump, and will seriously affect the actual flow of the pump to Q decline. On the contrary, if the pump head selected too high, but the actual operation of the lift is too low, is also affecting the pump efficiency and decrease caused by actual operation when the flow is too large, it is likely to increase the pump power beyond the rated current of the motor and the heating.
Q:Water pump in crested geckos cage?
Cresteds can drown, so is this one of those water fountain dishes? Make sure it's safe. If it is just a filter sound it may not hurt them, but I would be more afraid of them getting inside of something. Cresteds only need humidity hikes once or twice a day, if it is too wet and humid all the time, they develop respiratory illness.
Q:How to change the frequency of a water pump with a pump?
The water pump with frequency conversion is set correctly and will not burn the motor. If there is a problem, the frequency converter will automatically stop running. The frequency converter can change the positive and negative (frequency changer without this function, change the phase sequence)
Q:bmw 2745i water pump?
Usually car manufacturers estimate that most car parts (like a water pump) would last the warranty period and this means 40k to 50k miles. Original water pumps from dealers which are installed during car repairs are usually warrantied for 2 years. Of course this can be voided by driver abuse such as overheating the car or low coolant level.
Q:water pump problem,heats up only when i drive?
The short answer to your question: It is unlikely that a water pump will go bad without leaking, but weirder things have happened. Your thinking is right overheating only when you drive is an indication of limited flow, either caused by a restriction (radiator, hose, thermostat), an air bubble, or a bad pump. Are you sure that the air is bled out of your system? If you have an air pocket in your engine or at the pump, you will get reduced flow. I think that the 4.7 Durango has a radiator cap, if so, with the engine cold, take the cap off, fill it, and start the engine. If you get bubbles every time you rev the engine, then you may have a bad head gasket, this would introduce bubbles in the system... Make sure that the lower radiator hose is not collapsing. Most of these hoses have a stiff spring inside to keep them from collapsing when the water pump is running. Otherwise, my guess would be that your pump is bad, or you have more restrictions in your system. Good luck.
Q:Do you need to replace the water pump on your car when replacing the water pump gasket?
some vehicles have diverse designs. The water pump on my ninety six Century would have been finished in a rely of minutes. the place as some are plenty deeper in the engine. frequently, to alter a water pump like that's rather plenty one greater step than changing the timing belt. for this reason it quite is mostly a great theory to do them the two at as quickly as.
Q:how does a water feature pump work?
Hi. Most pumps work by squeezing the water through a nozzle. A water feature pump is usually hidden from view but still works the same way as any other pump. A motor turns the device that pushed the water.
Q:Water pump 99 ranger?
A water pump for your truck costs $63 at Autozone. I can't imagine where you got those prices at. Take the belt off and turn all the pulleys by hand. You should be able to tell which one is bad. Water pumps don't have bearings. The shaft just rides in a bronze race.
Q:water pump leak headache?
never rule out a freeze plug. it could also be a cracked block. it could be in your interest to pressurize the system and trace the leak back to the source. the pump could be fine.
