1.Multi-stage Pump Introduction:
QD, QDG series Horizontal Boiler Feed Water Pump.High Pressure Multistage Pump
Description: QD, QDG series centrifugal multistage pumps and QDL series vertical multistage centrifugal pumps are multiple single stage impeller combined together makes head high.
They are used for pure water and liquids with concentration less than 1%, particles smaller than 0.1mm, or liquids similar to water in physico-chemical property. QD series pump's medium temperature can not exceed 80ºC, QDG series can not exceed 150ºC. Head: 76-1080m, flow rate: 3-600m3/h.
We can use different materials of HT200, QT500, ZG500 stainless steel etc by different medium.
1) Easy installation and move;
2) Pump body support by anchor assure the stable structure and maximum resistance off-center and distortion caused by line load;
3) No overload design, make sure performance operate stably;
4) Adopt national standard hydraulic model make sure high operation efficiency and good anti-cavitation performance;
5) Packing seal and mechanical seal are available.
