1. Broad impeller path created by single casing and clamp bands connection.
2. Unique design to make maintenance and wet parts replacement convenient.
3. Dig deep advantage, good dig deep effect within 30 meters.
4.Using a variety of speed and modifications to make pump running under best condition.
5.Excellent NPSH performance, long service life, high efficiency ,which can meet many poor transport conditions.
6. The discharge direction of pump can be oriented in any direction of 360°.
7. Driving type mainly have V belt drive, elastic coupling drive, gear reducer drive, hydraulic coupling drive, variable frequency driven etc.
8. Packing seal, Expeller seal and Mechanical seal are available as per different application.
It adopt international advanced technology, non-clogging design with big flow channel and 3-Vane high efficiency closed impeller. Large solid particles are allowed.
● Casing – single casing be made of high-chrome alloy, provide long wear time.
● Impeller – 3 vanes impeller, processing larger solids easily. The impeller and casing are threaded connection,no need nuts. High efficiency and high head designs are also available.
● Cover plate – wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.
● Bearing assembly – a large diameter shaft with short overhang minimizes deflection & contributes to long bearing life.
● One-piece frame – a very robust one-piece frame cradles the cartridge type bearing and shaft assembly. An external impeller adjustment mechanism is provided for easy adjustment of impeller clearance.
Bearing assembly advantage features:
1.A large diameter shaft with short overhang minimizes deflection and contributes to long bearing life.
2.Four through bolts are required to hold the cartridge type housing in the frame.
3.The removable cartridge-type bearing assembly facilitates easy on-site maintenance procedures.
4.Provided with hardened shaft sleeve to protect the shaft .
5.Grease purged piston rings to help seal contaminates out of bearing housing.
