First, the product overview TSWA pump horizontal, single suction, multi-stage, multi-stage segmental centrifugal pump. For the transport of water or other physical and chemical properties similar to water. It is also possible to change the material of the pump overcurrent unit, the form of the seal, and the addition of a cooling system for conveying hot water, oil, corrosive or abrasive-containing media. TSWA multistage centrifugal pump structure of the product implementation JB / T1051-93 "multistage centrifugal pump type and basic parameters" standard. Second, the product features 1, running balance, low noise: the use of low-speed motor, so that the series pump has a balanced operation, low noise and so on. 2, shaft seal: the choice of using soft packing seal or mechanical seal, safe and reliable seal, simple structure, cheap, easy maintenance. 3, the whole machine long life: Shaft full seal structure, to ensure that no contact with the media, no corrosion, long service life. Third, the working conditions Flow range: 5 ~ 200m3 / h Head: 10 ~ 300m Speed: 1450r / min Medium temperature: -15 ℃ ~ +80 ℃ Ambient temperature: ≤ +40 ℃ System maximum working pressure: ≤3.0MPa
