▼Product introduction

The ZJ type pump is a single-stage, single-suction centrifugal slurry pump. The pump body adopts an inner and outer double-layer metal structure, and the pump casing is a vertically split type. The outlet can be rotated to eight different positions at 45° intervals. This product is highly efficient, energy-saving, has a long service life, is lightweight, has a reasonable structure, reliable operation, and is easy to maintain. It is suitable for industries such as power, metallurgy, coal, and building materials.

▼Application environment

Suitable for industries such as power, metallurgy, coal, and building materials, it treats abrasive or corrosive slurries containing solid particles. The solid-liquid mixture concentration is 45% for mortar and 60% for mineral slurry.

▼Product features and advantages

Wear-resistant and durable: Utilizing wear-resistant materials such as high-chromium alloys, the flow-through components are robust and specifically designed for conveying abrasive slurries, resulting in a long service life.

High efficiency and energy saving: Excellent hydraulic model and rational structural design ensure efficient operation even under high-concentration conveying conditions, reducing energy consumption.

Reliable structure: Compact structure, diverse shaft seal types with good sealing performance, smooth operation, low vibration, long maintenance intervals, and high reliability.

Leak-free design: Especially for submersible pumps, which operate submerged in liquid, the problem of shaft seal leakage is fundamentally solved, ensuring safety and environmental protection.

▼Working principle

Purchase Recommendations: Determine the pump model and material (e.g., high-chromium alloy) based on the concentration, particle size, and corrosiveness of the slurry being pumped. The operating conditions determine whether to choose a horizontal or submersible pump. Always refer to the manufacturer's performance curves to match the flow rate and head.

Maintenance Recommendations: Regularly inspect vulnerable parts such as shaft seals and bearings. Pay attention to abnormal vibrations and noises; immediately stop the machine and investigate. Ensure spare parts are from reliable sources and that regular maintenance and replacement are performed by qualified personnel.

▼Shopping and maintenance suggestions

Key Selection Points: Choose the model based on your flow requirements, paying attention to the pump body material and motor protection rating (IP54 or higher recommended).

Common Faults: No water output may be due to insufficient pump priming, air leaks in the pipeline, or impeller blockage. For initial use, fill the pump with priming water.

Maintenance Schedule: Replenish bearings with grease every six months, inspect the mechanical seal annually, and drain any remaining water to prevent rust if the pump is to be out of service for an extended period.

▼Precautions for use

Pre-start checks: Ensure the pump and pipeline are properly sealed, and that the lubricating oil level in the bearing housing is normal. Avoid idling or dry running.

In-operation monitoring: Carefully observe the pressure, flow rate, and motor current to ensure operation within the rated range and prevent blockages and overloads.

Post-shutdown maintenance: Before stopping the pump, flush the pump chamber and pipeline with clean water to prevent solid particle accumulation. Regularly check the wear of vulnerable parts.
