Slurry Pump

Head: 9.1-66.99 M

Capacity: 4.5-3300 (m³/h)

Applications: Slurry pump is widely used in mining, metallurgy, power generation, chemical industry, dredging, and other industries. These pumps are used to transport various ore slurries (gold, iron, copper, lead, zinc, tungsten, tin, lithium, etc.); ash and coal slurries from thermal power plants; slag and steel slag from metallurgical plants; river sludge; sand and gravel aggregates, construction waste slurries, and seabed ore sand; corrosive chemical slurries; construction mortar; and other liquid-solid mixtures containing solid particles.

introduction of Slurry Pump

Slurry pumps are specialized industrial auxiliary equipment designed for conveying high-concentration slurries containing solid particles. It can efficiently handle a variety of high-concentration, high-temperature, and corrosive slurries. It is commonly used in applications such as slurry transportation, hydraulic ash removal, river dredging, and tailings treatment. Available in a variety of configurations: single-stage, multi-stage, horizontal, and vertical. It can adapt to a variety of extreme operating conditions. Variable frequency drive technology enables precise flow control. These slurry pumps can be connected to silos, crushers, filters, and other equipment to continuously transfer solid-liquid mixtures such as slurry and ash, replacing manual or inefficient conveying methods.

Powered by centrifugal force, the slurry pumps utilize a highly wear-resistant double-layer pump casing and composite sealing system. They are key equipment for efficiently conveying high-concentration, large-particle, and highly corrosive solid-liquid mixtures in industries such as mining, power generation, and environmental protection. It offers core advantages such as long life, low energy consumption, and adaptability to extreme operating conditions. Their modular design makes them the preferred feeding solution for slurry conveying operations under harsh conditions.

Slurry Pump Application Scenarios:

  • Mining and Mineral Processing: Transporting tailings, concentrate slurry, and high-concentration slurry in flotation processes.
  • Coal Washing and Processing: Treating coal slurry, heavy media suspensions, and coal washing waste.
  • Metallurgical Industry: Transferring highly corrosive slurries such as smelting slag and red mud.
  • Power Industry: Transporting limestone slurry from coal-fired power plant slag discharge and desulfurization systems.
  • Dredging Projects: Pumping mixtures of silt and water during river and port dredging.
  • Chemical Industry: Transporting mixed liquids containing crystalline particles or corrosive chemical media.
  • Environmental Treatment: Dewatering sludge from wastewater treatment plants and recovering industrial waste.

Features Of slurry pump

1. Metal Material: anti-wear, abrasion, and abrasion resistance.

2. High efficiency, long life, smooth operation.

3. Drive mode: directly connect the drive (DC), Fluid coupling drive (HC), and belt drive (CR, CL, ZV, CV).

4. Structure Features: The slurry pump body adopts a double-layer pump shell mechanism. The double-shell pump shell structure is vertical in the open type. The water outlet position can be 45° of an interval, rotating 8 different installations.

5. Outlet diameter optional: 350mm, 300mm, 250mm, 200mm, 150mm, 100mm, 80mm, 65mm, 50mm, 40mm.

Principle and structure of slurry pump

working principle

The motor drives the impeller at high speed. Centrifugal force propels the medium inside the impeller into the volute-shaped pump chamber, creating a negative pressure zone at the center of the impeller. External slurry, under atmospheric pressure, enters the impeller through the suction pipe. Simultaneously, the ejected medium decelerates and pressurizes within the volute, converting kinetic energy into static pressure energy before ultimately being discharged through the outlet pipe. The auxiliary impeller balances axial forces, and the shaft seal system prevents leakage. Frequency conversion speed regulation is used to achieve a continuous “suction-pressurization-delivery” cycle, with both flow rate and head controlled by the variable frequency drive.

    Adjustment: Axial clearance adjustment mechanism.

Why Choose JXSC slurry pump

  • High wear resistance: Flow components can be made of high-chromium alloys, wear-resistant rubber, etc., with wear resistance three times that of ordinary cast iron, suitable for corrosive media conditions, and with a longer service life.
  • Strong corrosion resistance: Special alloys or rubber-lined designs are available for acidic/alkaline slurries.
  • Anti-clogging: Adopting a wide-channel, large-clearance impeller design, it eliminates the problem of jamming and stalling, suitable for conveying large-particle slurries.
  • Energy-efficient and high-efficiency: Optimized hydraulic model, efficiency is 15-20% higher than ordinary pumps.
  • Easy maintenance: Modular structure, quick replacement of wear parts (such as impellers and wear plates).
  • High head capacity: A multi-stage series design can achieve a head of over 100 meters.
  • Stable operation: Heavy-duty bearings and a balancing system reduce vibration, suitable for 24/7 continuous operation.
  • Wide adaptability: Supports customized slurry pump outlet direction, power, and materials to match different working conditions.
