Slurry Feed Pump

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.

The Slurry Feed Pump is a centrifugal unit specifically engineered to deliver constant pressure and flow to downstream separation equipment such as hydrocyclones, filter presses, and centrifuges. Its construction features abrasion-resistant wet-end parts made from high-chrome alloy or wear-resistant rubber, designed to withstand the high erosion caused by solid-laden fluids. The hydraulic design focuses on maintaining a stable discharge pressure to ensure separation efficiency, utilizing robust shaft sealing systems like mechanical seals or expellers to prevent leakage under fluctuating feed conditions.

Frequently Asked Questions (FAQ)

Q1: What are the drive arrangement options for this pump?
A: We offer various drive configurations to suit installation space and speed requirements, including Direct Connection (DC), V-Belt Drives (CRz, ZV, CV), and Gearbox Reducer drives.

Q2: How do I select the correct pump model for hydrocyclone feeding?
A: Selection requires specific operating data, including the required slurry flow rate, total dynamic head (pressure), specific gravity of the slurry, and the particle size distribution. We match these parameters to the pump performance curve to ensure optimal efficiency.

Q3: Are the wear parts interchangeable with other standard brands?
A: Yes, the impellers, volute liners, and throat bushes of our standard series are dimensionally compatible with most major international slurry pump standards, facilitating easy maintenance and part replacement.
