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:1978 Ranchero 500. Pumps leaking like crazy. I have a belt to remove, which i assume is the serpentine belt? Its tight as can be on the pulleys. I have no clue how to remove this and any other advice on this do-it-yourself project would be much appreciated. Thanks
You can loosen alternator, or power steering pump, or jump belt off of idler pulley if it has one. But I doubt that it is a serpentine belt, just a v-belt.
Q:Who knows? Is the motor with a pump a squirrel cage induction motor?
The motor with water pump is usually squirrel cage asynchronous motorThe squirrel cage asynchronous motor structure and single-phase asynchronous three-phase asynchronous motor of three-phase asynchronous motor motor is similar with a three-phase winding embedded in the stator slot (a single chain, single-layer concentric and cross layer structure of three kinds). The stator winding access three-phase AC power, rotating magnetic field winding current and induced current in the rotor conductor, the interaction of rotor current and air gap induction in rotating magnetic field, and electromagnetic counter (asynchronous transfer cabinet), the motor rotation.Three-phase asynchronous motor. It consists of two parts, stator and rotor. The air gap is between the stator and rotor. Rotor winding is used to generate induction potential, squirrel cage asynchronous motor, Jingjiang Ming art spring factory and produce electromagnetic torque, it is divided into squirrel cage and winding type two. Squirrel cage rotor winding is their winding short circuit, a conductor on the rotor in each slot discharge (material is copper or aluminum), than in the long core conductor, two ends of the iron core with two end ring conductor, the formation of short circuit winding. If the core is removed, the remaining windings are like squirrel cage, so it is called squirrel cage winding.Advantages and disadvantages of squirrel cage asynchronous motorsThe squirrel cage induction motor has the advantages of simple structure, easy manufacture, low cost and convenient operation and maintenance. It is widely used in industry and agriculture as the prime mover of electric drive.Its disadvantage is the poor speed performance and small starting torque, so some other types of motors are used in some situations which require smooth speed regulation and large starting torque.
Q:What's the difference between a cold water pump and a hot water pump?
Water seal and sealing quality is different?
Q:I have a 1997 mercedes 320e and it is leaking very bad. I need a temporary fix for the water pump, so that I can take it to the repair shop that is 10 min. away.
i don think you can do nething that will fix it temp...i would load your raidator up with coolant and put the heat on max to take the heat away from the engine put ur hazzards on and drive no more than 20mph...or have some 1 tie a thing tow rope arounf the front of the frame and have them pull you
Q:I am about to replace the timing belt in a 3.4L Toyota V6 at approximately 85,000 miles. The motor has had the Toyota red coolant, which lubricates a water pump very well. Should I, Or should I not replace a Toyota Water Pump also, at this mileage (85,000)? Could the original water pump last until 170,000? Thank you
i think different 2- do no longer bypass to the Toyota stealership. they're heavily overpriced. The timing belt service (-which could incorporate changing timing belt, crankseal, cam seal, waterpump andcontinual belts) could be extra useful like $600-750. The pan gasket- in case you fairly choose it comprehensive- would choose to correctly worth you (worst case challenge) $a hundred and fifty. All this would properly be comprehensive at any autonomous restoration shop for fantastically decrease than the stealership. learn around nonetheless because of the fact some independents can value you a lot as plenty because of the fact the stealership. additionally, there are shops available with super costs that do shoddy paintings- yet from my adventure, many of the plenty much less severe priced shops seem in elementary terms as reliable because of the fact the stealership.
Q:Where is the water pump located on a 1993 mitsubishi eclipse with a 1.8 motor
it is belt driven pulley near the center of engine, unless mitsu made that one timing belt driven in which case you can't see it with-out dissassembling front part of engine.
Q:I will be replacing my timing belt soon. The dealer is suggesting that I also replace the water pump. Is that really necessary? When do water pumps normally go out?
Look at it this way. It is not just the dealer making this recommendation, it's every good mechanic out there plus Gates belt company who has no stake in it, they recommend replacing water pump and the car manufacturer says the same. No one is trying to rip you off but they are trying to save you money. In answer to your question about when do water pumps normally go out, the answer is right after you change just the timing belt and everything is buttoned back up. Trust me, it happened to a friend who tried to save money.
Q:I need a new timing belt and I'm getting that done soon, but my mechanic says that water pumps are usually replaced along with the timing belt at the same time. Does it really need replaced?
i have a nissan pickup and i changed the timing set at 88k miles and opted not to change the water pump. bad move, since my water pump was driven from my timing chain. the new timing set put more stress on my water pump than the old slacked one did, and about 6000 miles later the seal on the inner water pump shaft started leaking and filled my oil with water. it took about a week for the mechanic to diagnose the problem and cost me 550 dollars in labor and parts. should've changed the water pump when i changed the timing set. could've saved 300 dollars in the long run. now if you have a belt driven water pump, like that in a chevy truck then it should be fine.
Q:Horizontal pumps, vertical pumps, which kind of expensive?
Not expensive, depending on the specific model, in fact, the vertical pump is not much
