Product Description
1.Multistage Pump Introduction:
1.Multi-stage Pump Introduction:
QD, QDG series Centrifugal Multistage High Pressure Water Pump
Description: QD, QDG series multistage centrifugal 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.
Pump Application
Suitalbe for mine, city Water Supply and Sewerage Engineering
Transfer watery liquid medium, without solid particle, temperature under 80°C
Suitable for boiler water feed or deliver medium similar with hot water, without solid particle, temperature below 105°C
Suitable for stain steel, mine, sewage transferring process.
Transfer mine water with solid partical content under 1.5% or similar sewage, temperature under 80°C
Suitable for transferring Corrosive liquid without solid partical, temperature between -20°C~105°C
Suitable for transferring Oil and petroleum products without solid partical, temperature between -20°C~150°C, viscosity under 120cSt
Applications List
For this series horizontal multistage centrifugal pump, both ends of it are supported, the casing portion is in a sectional form. it is connected to and actuated by a motor via a resilient clutch and the rotating direction of it. viewing from the actuating end. is clockwise. Refer to Fig. I for the structure of it.
Stator portion
Consists of suck-in section. middle-section, spitting section, guide vane, packing etc., which are linked together with a take-up bolt. with both suck-in and spitting mouths vertically upward.
Rotor portion
Consists of a shaft, impeller, balancing disk, muff etc. Parts.
Bearing portion
The whole rotor is supported by the roller bearings or
sliding bearings on both ends of the shaft and the bearings are lubricated with grease or 20# engin oil.
Cooling and seal of pump
The joint-part between suction section, intermediate
section and discharge section with be coated with molybdenum disulfide lubricating grease as seal. Rotor and fixed parts will be sealed by seal ring, guide-vane jacket and packing. The packing tensile degree of shaft seal should be proper and seep should be feasible dip by dip Unload run should be forbid. The seal ring and guide vane jacket should be replaced if they are too worn to be used any more and even do harm to pump work. There is spare shaft sleeve near shaft seal to protect shaft of pump.
