Disc Centrifugal Slurry Pumps
Enhanced Apex Filter Press Pumps with VFD Technology
Apex Filter Press Pumps are designed to support various filter press sizes, featuring advanced Variable Frequency Drive (VFD) technology for superior operational control. This technology enables variable speed operation, starting with high flow rates and low pressure, to facilitate the initial formation of the filter cake. This phase is crucial for preventing early clogging of the filter cloth by avoiding the development of a dense, impermeable solids layer too soon.
As the filter press filling cycle continues, the VFD controller works alongside the pump to automatically and gradually increase the feed pressure. This controlled pressure ramp-up can be adjusted based on slurry characteristics and solids concentration, ensuring optimal filtration performance.
The filtration process typically begins at a low pressure of around 25 PSI, gradually increasing up to a shut-off pressure of approximately 100 PSI, depending on the specific needs of the filter press. Once the target pressure is achieved, the pump automatically shuts off, ensuring precise and efficient operation throughout the filtration cycle.
This automated pressure management not only boosts filtration efficiency but also prolongs the life of filter cloths by preventing clogging and maintaining consistent filtration quality. The flexibility of the Apex VFD system allows for smooth integration with both new and existing filter press installations, making it an adaptable and valuable solution for optimizing industrial filtration processes.

Unmatched Durability for Abrasive Liquid Handling
Conventional pumps often struggle with abrasive liquids, leading to reduced performance and frequent maintenance. The Apex rotating disk pump, however, is designed to resist this. Its innovative design guides fluid flow between two parallel disks, creating a stable, quiescent film close to the disk surfaces. This boundary layer minimizes abrupt directional changes and rapid accelerations, preserving the pump’s surfaces and dramatically enhancing its resistance to abrasion.
Thanks to this advanced design, the Apex rotating disk pump provides exceptional durability and reliability when handling abrasive slurries, delivering consistent and long-lasting performance even in the most challenging environments.

Low NPSH Requirement for Optimal Pump Performance
In challenging operational environments, such as those encountered in South Africa, pumps often face issues related to variable pressure distribution caused by vanes moving through fluids. This can lead to cavitation, particularly at points of lowest static pressure, usually near the vane outlet. The Apex Disk Pump addresses these challenges with disk impellers that feature inherently low Net Positive Suction Head Required (NPSHR) characteristics. Additionally, the pump is equipped with an integral axial flow inducer, further enhancing its ability to operate with a low NPSH, making it a reliable solution for demanding applications managed by Pump and Dredge Africa.
The Apex Disk Pump is engineered to create a uniformly tangential pressure field throughout the system, ensuring that the pressure gradient remains consistently positive. This uniform pressure distribution is crucial for sustaining pump efficiency and longevity, especially in harsh conditions typical of industrial operations in South Africa.
Enhanced Performance with Highly Viscous Liquids
Traditional vaned impellers often struggle with highly viscous fluids, leading to reduced efficiency, lower capacity, and increased NPSH requirements. Fluids with viscosities around 500 SSU can significantly hinder the performance of conventional pumps.
The Apex Disk Pump’s unique design, featuring optimized disk spacing, enables it to handle a wide range of fluid viscosities effectively. From water-like fluids to those as viscous as 400,000 SSU, this pump stands out for its versatility and adaptability across various industrial applications.
The pump’s design allows it to adjust its flow characteristics based on the fluid’s viscosity—maintaining marginal turbulence for thinner liquids and transitioning to laminar flow for more viscous substances. This adaptability enhances the pump’s efficiency and ensures consistent, dependable performance, making it the ideal choice for managing diverse fluid densities and viscosities in industrial settings.
