The FYH type long shaft submersible pump belongs to a single-stage single suction vertical pump. It is a new, energy-saving and environmentally friendly product independently designed and developed according to market demand, used for conveying neutral or corrosive clean liquids. Especially suitable for industries such as sewage treatment, cement plants, power plants, and petrochemicals.

-ISO2858 Axial Suction Centrifugal Pumps (16 bar Class) - Markings, Rated Performance Points, and Dimensions
-GB5656-94 Technical specifications for single-stage single suction chemical centrifugal pumps
-GB/T3214-91 Test method for water pump flow rate
-GB/T3216-2005 Rotary Power Pump, Hydraulic
The FYH submersible pump mainly follows the markings and rated performance points in the ISO2858 standard.

Washing method
Introducing clean liquid to flush the sliding bearings ensures the safe transportation of the pump. There are two ways to choose for different media.
Self flushing
When the pumped medium is a clean medium, use this method for flushing. A pipeline is introduced from the pump outlet flange to allow the flushing liquid to flow towards each sliding bearing, lubricating the sliding bearings and taking away the heat generated by the friction pair, thus playing a cooling role.
External flushing
When the pumped medium contains smaller particles, this method is used for flushing. Connect a pipeline from the outside, introduce clean flushing solution to rinse each sliding bearing, lubricate the sliding bearings, take away the heat generated by the friction pair, and play a cooling role. Meanwhile, prevent solid particles from entering the friction pair.

Widely used in chemical, petroleum, power, metallurgy, synthetic fiber, medicine, food, papermaking, sewage treatment and other sectors for transportation, it can also transport corrosive liquids containing suspended particles.
