Project Description


Sproull® ZMJ  Slurry Pump is horizontal, cantilever, double casing, single-stage and single-suction centrifugal slurry pump. By internationally advanced solid-liquid two phase flow theory, our company newly designed this series of anti-abrasion and corrosion resistant slurry pump based on the principle of minimum hydraulic loss and abrasion. The fact that geometry of pump wet parts come in line with flowing state of pumped medium contributes to the reduction of local and whole coursehydraulic loss due to vortex and flow impact. Consequently, the abrasion of wet parts can be mitigated. The pump series have following benefits: complete range of specifications and performance, novel structure, high efficiency and energy conservation, low vibration, reliable operation, long service life, easy installation and maintenance etc.
Design, manufacture and quality of this series conform to Standard JB/T8096 Centrifugal slurry pumps.

Max Weight Concentration of Allowable Transferred Solid-liquid Mixture: Mortar(Slurry) and Coal Slurry≤45%、Pulp and Dense Medium≤60%.
Series: Two stages and multistage series connection, need toconfirm with technical department if more than two stages.
Materials: Hyper chrome alloy, Rubber, Polyurethane, Ceramic, Stainless steel etc.

Design features:

1. Adopting modern CAD design method, the hydraulic performance is excellent, the efficiency is high and the wear rate is low.
2. Wide Runner, good anti-clogging performance, excellent cavitation performance.
3. Axial inlet, radial outlet, outlet direction can be installed by rotating eight angles.
4. Adopt double pump shell structure design, split pump Shell for bearing pressure, lining for wear resistance.
5. Interchangeable metal lining and rubber lining, the impeller also has metal and rubber two materials.
6. The bearing assembly is designed with short cantilever and large shaft diameter to minimize deviation and vibration.
7. Various types of shaft seal: Packing Seal, Auxiliary Impeller Power Seal, mechanical seal and various special combination seal.
8. within the allowable pressure can be used in series.

Sproull® ZMJ  Slurry Pump is widely apply to mines, metallurgy, power, coal, chemical engineering, building materials and flue gas desulphurization peripheral system etc., and are used for delivering slurry with abrasive particles or corrosive slurry.

Mining & Mineral Processing
The slow running speeds of the Sproull Heavy Duty Slurry Pump, together with the comprehensive choice of abrasion resistant alloys and elastomers, provide unrivalled performance and service life for all abrasive mining and minerals processing applications.

Chemical Process
The interchangeability of alloy and elastomer components in the same pump casing, together with a wide range of mechanical seals, make the Sproull Heavy Duty Slurry Pump the most flexible choice for the chemical plant environment.

Sand & Gravel
Designed for easy and simple strip down and re-assembly, the Sproull Heavy Duty Slurry Pump minimises downtime, making it the ideal choice where installed stand by pumps are not available.

Sugar Processing
The premium reliability and service life of the Sproull Heavy Duty Slurry Pump is specified by many sugar plant engineers worldwide where uninterrupted pump operation during the sugar campaign is a critical requirement.

Flue Gas Desulphurisation
The new generation of specially formulated abrasion and corrosion resistant alloys, together with the very latest elastomer technology, positions Sproull Pumps firmly as a major supplier of pumps to the FGD industry.

Oil & Gas Exploration
Over a number of years we have developed the proven design of the Sproull Heavy Duty Slurry Pump ranges to suit the specific demands of offshore applications. We can now offer the most reliable top side solution to erosive wear.

Industrial Applications
Wherever abrasive solids are causing premature failure of pumps, the Sproull Heavy Duty Slurry Pump range has the right combination of performance, wear life and reliability to bring the customer the lowest cost of ownership.
