Mechanical booster pump ( zr 250 - The 4200 series) Working principle and method of use

zr 250 - 4200 series

ZAS series mechanical booster pump based on the principle of roots, mechanical booster pump is pressure range is 0. 01 to 10 low, not exposed to the same as the backing pump in the concentration of corrosive medium technology, therefore reliability of mbar need large pumping speed of the application of the most popular type. Generally need to supporting the front stage pump use, the former can pump drainage to the start-up pressure booster pump. Mechanical booster pump operation pressure is relatively low, not exposed in the first stage pump the same concentration of corrosive medium technology, a reliable xining is very high.

mechanical booster pump characteristic and the superiority

1. Applicable to pressure range of 0. To 50 mbar / 0 01. 0075-37. 5 Tor.

2。 Need large pumping speed applications

operation pressure is relatively low.

3。 A high reliability. ZRS series belong to high quality, no oil pump structure.

( 1) Low noise, no vibration.

( 2) Durable, corrosion resistant.

( 3) Technique, technology has advanced shaft seal chamber without oil pollution.

4。 Effective shaft seal, oil will not be entering the pump cavity, and a lack of internal and external bypass line and these may corrode valve parts, so will need for maintenance to a minimum.

5。 To optimize the design of the shaft seal, in order to ensure lubricant not migrated to the pump cavity, make the pump in the environment of high clean for degree requirements play the performance of the pump. In addition, you can prevent the tolerance is very strictly convex Angle of rotor and dust particles collected in the end.

6。 Dynamic balance of rotor and precision grinding gear, smooth operation, mute of pump to meet the demand of the advanced technology and equipment manufacturers. Mechanical pump application

vacuum packing, low density wind tunnel, the application of mechanical booster water pump, vacuum packaging, drying and degassing, vacuum metallurgy, vacuum distillation, film coating, low density wind tunnel, the space simulation, vacuum impregnation, freeze drying.

mechanical booster pump hydraulic transmission technology

ZAS series pump has a unique patented hydraulic transmission device, it will be the motor connected to the pump body, the hydraulic transmission device has the following advantages.

1。 Shorten the extraction time was 50%

2. No pressure sensor, the by-pass pipe or valve

3. Reduce the investment and operation cost

4. After the match before the pump, can be in continuous operation under all pressure

1. Extraction time shorten 50%

hydraulic transmission technology makes can pump and backing pump start at the same time, and prevent the startup motor overload. ZAS series pump, therefore, helps to reduce the extraction time of system

2. Automatic overload protection

hydraulic transmission device can automatically adjust the rotational speed of the water pump, thus preventing motor overload, overheating, pump can also be run under high pressure.

3。 Cost savings

choose to use ZRS series mechanical booster pump, can achieve installation and operational cost savings. Because do not need to be equipped with valve, by-pass pipe and pressure switch, and compared to the conventional drive pump can also be equipped with the required smaller backing pump, so it can save investment cost.
