Description
I. Product Features
- Adoption of modern CAM design methods, good hydraulic performance, high efficiency and low wear rate.
- The combination of packing seal and mechanical seal for auxiliary impeller to avoid the leakage of slurry.
- Wide flow channel, good anti-blocking properties, superior cavitation performance.
- Reliable design ensures the overall mean time between failures (MTBF) is greatly improved.
- The adoption of thin oil lubrication, metric bearings, a reasonable set of lubrication and cooling systems, to ensure the bearing running at low temperature.
- The wetted parts made of high-chromium alloy are with good wear-resisting and corrosion-resistant performance.
- The multi-level series can be used within the allowable pressure range, the maximum allowable working pressure is 3.6Mpa.
- ZGB series slurry pump mainly uses direct drive, and its flow rate and the pump head is adjusted by cutting impeller diameter.
- The pump has fewer specifications and models, it is more convenient to select.
- Reasonable structure, high efficiency, reliable operation and easy maintenance.
II. Application
It is applicable for delivering high-lift slurry with certain corrosion in the field of electric power, metallurgy, mining, coal, building materials, chemical and so on.
Seal type: the shaft seal of ZGB series slurry pump has two forms: the combination of auxiliary seal and packing seal, and mechanical seal.
- Auxiliary impeller with dynamic and packing seal: auxiliary impeller is sealed by the pressure between the impeller and the tandem auxiliary impeller, and packing or lip seal seal ring is as shut-down seal. The first-stage pump of single or multi-stage pump can adopt the sealing form, when the pump inlet pressure is not greater than 10% of the outlet pressure. It has advantages of running withoutshaft seal water, not dilute pulp, good sealing effect, etc. However, it increases the power consumption (generally about 5% of the shaft power). Packing seal is a common shaft seal form for a variety of working conditions. PTFE packing, graphite packing and other special materials can be matched. It is applicable for corrosive or high temperature conditions, which has advantages of simple structure, easy maintenance, etc.
- Mechanical seal: The world's leading sealing technology, good sealing effect. Cartridge construction makes installation and replacement more convenient, different structure adapts to different working condition. Auxiliary friction materials adopt high hardness alloys and ceramic materials, the design and coordination of mechanical seal and sealing box meet the flow state of medium, which results strong abrasion resistance and shock resistance. Then, it can satisfy customers in a variety of harsh conditions.
