Disc Centrifugal Slurry Pumps
Optimized Operation of Apex Filter Press Pumps with VFD Technology
Apex Filter Press Pumps, designed to suit various filter press sizes, utilize advanced Variable Frequency Drive (VFD) technology. The VFD enables variable speed operation, starting with high flow rates and low pressure, to initiate filter cake formation. This prevents premature clogging of the filter cloth by avoiding the early formation of a dense, impermeable coating of solids.
During the filter press filling cycle, the VFD controller works with the pump to automatically and progressively increase feed pressure. This gradual pressure increase, adjustable based on slurry characteristics and solids concentration, ensures optimal filtration efficiency. The process typically starts at a low pressure of 25 PSI and increases to a shut-off pressure of around 100 PSI, depending on the filter press specifications. Once the desired pressure is reached, the pump shuts off automatically.
This automated pressure adjustment enhances filtration efficiency and extends the lifespan of the filter cloths by preventing clogging and ensuring consistent filtration quality. The flexibility of the Apex VFD system allows integration with any existing or new filter press setup, making it a versatile solution for improving industrial filtration processes.
Enhanced Durability Against Abrasive Liquids
Abrasive liquids containing suspended particles can significantly wear down surfaces. In the Apex rotating disk pump, the fluid flows between two parallel disks, creating a boundary layer—a relatively stable, quiescent layer adjacent to the disk walls, primarily influenced by the Reynolds number. This design minimizes abrupt directional changes and rapid accelerations, preserving the boundary layer’s protective properties and enhancing the pump’s resistance to abrasion. This ensures outstanding durability and reliability when handling abrasive slurries.

Low NPSH Requirement
When a vane moves through a fluid within challenging environments like those in England, it produces a variable pressure distribution. This distribution manifests as a positive pressure on the advancing face of the vane—higher than the primary fluid pressure—and a negative pressure on the opposite side. The extent of this differential depends on the radial flow velocity and the disk velocity, a characteristic integral to vaned impellers. In such impellers, cavitation is most likely to occur at the point of lowest static pressure, typically at the vane outlet and particularly on the retreating side.
Disk impellers used in the Apex Disk Pump feature relatively low Net Positive Suction Head Required (NPSHR) characteristics. The Apex impeller is uniquely designed with an integral axial flow inducer that further enhances its low NPSH capabilities, making it a robust solution for demanding applications facilitated by Pump and Dredge Solutions in England.
The Apex Disk Pump is engineered to generate a tangentially uniform pressure field across the entire system, ensuring that the only pressure gradient present is positive. This uniformity is crucial for maintaining the pump’s efficiency and longevity, especially in regions like England, where operational conditions can be severe.
Optimized Performance with Viscous Liquids
Handling viscous liquids often challenges traditional vaned impellers, negatively impacting efficiency, capacity, and NPSH requirements. Viscous fluids, particularly those around 500 SSU, can significantly decrease the performance of these impellers.
In contrast, the Apex Disk Pump excels in managing highly viscous fluids without these drawbacks. This pump utilizes an innovative design where proper disk spacing is critical to accommodating fluids of varying viscosities. This unique feature allows the Apex Disk Pump to efficiently handle fluids with viscosities ranging from as low as water to as high as 400,000 SSU.
Moreover, the design of the Apex Disk Pump ensures that the flow characteristics adapt to the fluid viscosity—remaining marginally turbulent for thinner liquids and transitioning to laminar flow for more viscous substances. This adaptability enhances the pump’s efficiency and ensures consistent performance across a broad spectrum of fluid densities and viscosities.
