Technical Data
Flow rate: up to 90 m³/h
Head: up to 1,900 m
Product Series: CWH
Design
SIHIcombitube CWH is a single stage, pitot tube pump. The liquid enters the pump via the suction line, passes the mechanical seal (the mechanical seal is under suction pressure only) and enters the rotor where it is accelerated up to the rotor speed. Owing to the rotational speed of the liquid, it has kinetic energy. A stationary wing shaped pitot tube is placed inside the rotor and has a circular opening near the inside wall of the rotor. The liquid enters the pitot tube at high velocity due to the centrifugal force created by the rotor casing and the kinetic energy of the liquid is converted into pressure as the liquid passes along the diffuser section of the pitot tube. This results in a continuous, high pressure flow of liquid from the pump discharge. |

Application
SIHIcombitube has been developed for low flow, high head applications. The pitot tube design produces a stable, pulsation free flow. The ability of the pump to operate with minimum flow makes the pump suitable for a wide range of applications within its performance envelope.
SIHIcombitube is used in a wide range of industries including chemical and petro-chemical, plastic and rubber processing, paper mills, steel mills, sugar refining, cereal and food processing and automotive. Within these, SIHIcombitube is used for cleaning, descaling, reactor feed, boiler feed, transport and process duties, system pressurisation and spray systems. |
