Product Q&A

Q:What working medium is this multistage boiler feed pump applicable for?

Mainly deaerated hot boiler feed water; also applicable for clean hot condensate water, low-corrosion hot medium below 150celsius degree Not for medium with solid particles or strong corrosive liquid.

Q:What is the standard design temperature & pressure range?

Normal medium temp: <160 celsius degree; discharge pressure covers 1.6MPa ~16MPa, customizable stages for ultra-high pressure industrial boiler.

Q:Can pump material be customized for special water quality?

Yes. Standard: cast steel casing + 416SS impeller; upgrade option: SS321 / Duplex 2205 for feed water with trace chloride or slight corrosion.

Q:Is the pump compliant with Russian GOST & Kazakhstan EAC standards?

Pump design meets API610 BB4, corresponding GOST electrical & fire safety norms (SP 12.13130), supporting EAC certification for CIS market delivery.

Q:How to handle frequent boiler load flow variation?

Equip with frequency conversion motor or bypass regulating pipeline; pump hydraulic design reserves surplus flow margin for variable boiler working condition.
