Schurco Slurry® Z Series pumps are designed to handle very large particles for gravel and dredging operations.
Schurco Slurry® range of dredge and gravel pumps is designed specifically for continuous pumping of extremely aggressive slurries, with a wide particle size distribution. Its capability of handling large particles at consistently high efficiencies results in low cost of ownership. The large volume internal profile of the casing reduces associated velocities, further increasing component life.
The unique segmented clamp ring on larger size units and solid on smaller pumps facilitates casing rotation to any angle, reducing the need for costly high wearing bends. Minimal maintenance is required.
Impeller front and back shroud expulsion vanes reduce gland pressure and intrusion of high concentrations of solids in the gland area. Efficiency is maintained by minimizing suction side recirculation. Specially designed and shaped impeller vanes allow the handling of extraordinarily large particles. The unique casing design and sealing vanes prevent abrasive solids intrusion at the sealing faces.
Casing The large, robust casing has been designed to reduce internal velocities, resulting in minimum efficiency loss and improved casing wear life. The casing is made up of three components to reduce maintenance time and costs associated with a one-piece design.
Schurco Slurry offers multiple shaft sealing options to match the demands of each pumping application. Whether prioritizing simplicity, waterless operation, or leak-free performance, we provide sealing solutions that maximize reliability and minimize downtime.
Cartridge-style bearing housing allows for removal from pump and assembly in controlled environment
Oversized shaft diameters and reduced overhang in the wet-end contribute to long life and reliability in the field


A classic and reliable sealing method, the stuffing box uses packing rings compressed by a gland to restrict slurry leakage around the shaft. Still one of the most widely used slurry pump seals, it requires seal water supplied at a pressure higher than pump discharge pressure to function effectively.


The expeller seal is a dynamic, waterless sealing solution that uses centrifugal force to prevent slurry leakage while the pump is running. It’s an excellent choice for applications where external seal water is unavailable, undesirable, or difficult to maintain. By eliminating the need for gland sealing water, the expeller seal reduces operating costs and simplifies maintenance. A grease-packed static seal prevents leakage when the pump is idle. Ideal for moderate suction conditions, the expeller seal offers reliable performance in tough environments with minimal infrastructure.


Mechanical seals provide superior sealing performance in high-pressure, high-temperature, or environmentally sensitive slurry applications. They use precision-engineered rotating and stationary faces to form a tight seal around the shaft, minimizing leakage even under severe conditions. Schurco Slurry primarily utilizes cartridge-style mechanical seals, which are preassembled, self-contained units that simplify installation and improve reliability. Mechanical seals are ideal for corrosive or abrasive slurries, or in applications where leakage control is critical.
