Brief Description of pump vacuum pump
SHZ-D(III) table type anti-corrosion circulating water vacuum pump is on basis of multiple purpose circulating water vacuum pump, considered from the small laboratory area, referred to Japanese table model pump, and make improvements of one-time molding shell and reduced volume. SHZ-D(III) table type anti-corrosion circulating water vacuum pump has features of small volume, light weight, beautiful appearance, double-meter and double-end air exhausting, four-meter and four-end, it’s a multiple purpose vacuum pump whose both sides are the same, which is not only convenient for teacher to demonstrate, but also for students to turn on/off from any side.
SHZ-D(III) table type anti-corrosion circulating water vacuum pump’s engine body has double tapping, can be single used or parallel used with two vacuum meter. Main engine is made from stainless steel movement and anti-corrosion movement. It embraces advantages of anti-corrosion, no pollution, low noise and convenient to move, can also add vacuum control valve according to client needs. SHZ-D(III) table type anti-corrosion circulating water vacuum pump enables 4 students to conduct chemical experiments at the same time, and shrank experiment space.
Pump body is equipped with water as working liquid. When impeller is in clockwise rotation, water is threw by impeller to all around, because of centrifugal function, water forms a sealing circular ring which is similar with pump chamber shape in equal thickness. Bottom side surface of water ring just touch with impeller hub, upper side surface of water ring just on top with vane (actually vane has certain immersion depth in water ring). At this time, impeller hub has formed a crescent moon shape space between water ring, and this space is divided into several small chambers by impeller. If take bottom impeller as starting point, when impeller rotating in the first 180 degree, area of small chamber will increase, and connecting to admission port on end face, by this time gas is absorbed, when finishing gas absorbing, small chamber will isolated with the admission port; when impeller go on rotating, small chamber increased and gas is compressed; when small chamber is connected to exhaust port, gas was discharged from pump.
Product features of SHZ-D(III) table type anti-corrosion circulating water vacuum pump:
1. Equipped with circulating device, vacuum degree is stable, appearance is beauty, small and exquisite.
2. This product has double tapping, can be single used or parallel used with two vacuum meters.
3. Main engines is made from stainless steel material, box is made form engineering plastics. Anti-corrosion, no pollution, low noise and convenient to move.

Q: If the water temperature is too high for long-time working, will it have an effect on pump? Is it danger?
A: Water temperature too high will cause a large amount of vaporization in pump, which will reduce the efficiency of vacuum pump. Therefore, water temperature must be controlled, but in general, if environment temperature is below than pump’s working environment requirement, and has no water shortage, it will be OK.
Q: What’s the reason for vacuum pump’s displacement and vacuum degree is too low?
A: Please check if sealing part has air leakage. If there has no problem, please check the pump. See whether electric machine has inversion rotation, whether all valves have been opened, etc.
Q: What’s the reason for declining of vacuum degree?
Maybe there has air leakage in plunger or other places.
