The hydraulic slurry pump is a heavy-duty centrifugal unit designed specifically for the transport of abrasive, high-density slurries containing suspended solid particles. Structurally, it features a double-casing design where the inner wet-end parts are cast from wear-resistant high-chromium alloys or corrosion-resistant rubber, depending on the chemical properties of the fluid. The hydraulic mechanism utilizes a specialized impeller geometry that manages solid-liquid two-phase flow, ensuring the passage of coarse particles without clogging the volute liner. Shaft sealing options include packing seals, expeller seals, and mechanical seals, which are selected to maintain internal pressure and prevent leakage during high-load operations.

Industrial Applications

Hydraulic slurry pump systems are integrated into processing circuits within the mining, metallurgy, coal, and power generation industries. Primary applications involve the transport of mill discharge, cyclone feed, and copper mine tailings, as well as ash removal in thermal power plants and sludge disposal in wastewater treatment facilities. The equipment is compatible with various heavy media, including dredging sand from riverbeds and transferring corrosive slurries in chemical desalination projects, operating effectively in environments requiring the movement of high-concentration abrasive mixtures.

Frequently Asked Questions (FAQ)

Q1: What shaft sealing configurations are available for this pump?
A: We provide three standard sealing methods: gland packing seals for general applications, expeller (centrifugal) seals for preventing leakage without flush water, and mechanical seals for zero-leakage requirements in chemical or high-pressure environments.

Q2: Can the wet-end parts be interchanged between metal and rubber?
A: Yes, for many of our standard series, the wet-end components (impeller, volute liner, throat bush) are dimensionally interchangeable. This allows the pump to be converted from high-chrome alloy to rubber liners if the operating conditions change from abrasive to corrosive.

Q3: What parameters are required to select the correct pump model?
A: To determine the appropriate hydraulic slurry pump, we require the flow rate (capacity), total dynamic head, slurry specific gravity (density), particle size distribution, and the pH value of the liquid.
