Key features of the pitot tube pump
The pitot tube pump is different than a centrifugal pump. It offers a number of benefits like being very flexible and reliable. It also does not require much maintenance and is seize-proof as well. This kind of high pressure pump has just one stage pump which is made up of two main parts: rotating case and a stationary pitot tube. Also, this kind of high pressure pump has a single wearing rubber part which happens to be the mechanical seal that is affected only by suction pressure. In case of a seal leakage because of seal failure the leakage vents to the atmosphere.
The pitot tube pump is very flexible because the head is changed by speed change. It also has an operating range that is very wide and when the pitot tube is changed, it leads to large flow changes. It also delivers low minimum flow that is smooth as well as free of any pulsations.
The pitot tube pumps is also very reliable. It is a simple control equipment that does not require any relief valve and nor does it require by-pass pressure unloaders or pulsation dampeners. The design of this high pressure pump is very simple and it works with just two basic working parts which are a rotor and pitot tube. The bearings are isolated from pumped fluid and the pump is also resistant to system transients.
This high pressure pitot tube pump is a pump that requires minimal maintenance. Since this pump is designed to have low number of parts and it works well at low speeds, it does not cause any wear and tear or damage. The arrangement of all the parts in the pump also plays a part in ensuring low maintenance.
The pitot tube pump is different than a centrifugal pump in that it won’t seize in case the pump runs dry or when there is loss of suction. Finally, its simple and effective design also makes the pitot tube pump a very useful piece of equipment.
