API Centrifugal Pumps – with Speed more than 15000 rpm and Spare Parts
Application:
Petrochemical industries, refineries, power plants
Product Introduction:
OH6 pumps are high-speed API pumps that can provide significant heads and high pressures that other types of OH cannot produce. The main reason is the high impeller speed of these pumps, between 12,000-35,000 rpm, created through the integrated booster gearbox in the pump structure. This gearbox allows the pump in Off design conditions (higher or lower than the rated state) by controlling the speed of the electric motor. One of the features of this type of pump compared to other centrifugal pumps is the possibility of using a single-stage pump instead of using multi-stage pumps or several pumps in a series. This makes it possible to reduce the cost of repairs and maintenance in addition to reducing the footprint of the equipment. Another feature of these pumps is the possibility of using them in situations where the positive height head of the sucker pump is very low. It is worth mentioning that about 1-2% are of this type among the electro pumps of a petrochemical complex. These pumps are mainly delivered to customers as skids.
This product is used for transferring, injecting, and storing all process fluids, including volatile, corrosive, toxic and flammable, acidic, slurry, etc., in different temperature ranges.
