Enhanced Operation of Apex Filter Press Pumps with VFD Technology for Precision Control
Apex Filter Press Pumps from UAE Pump and Dredge are engineered to accommodate a wide range of filter press sizes. They are equipped with cutting-edge Variable Frequency Drive (VFD) technology. This system allows variable speed operation, starting with high flow rates and low pressure, to support early-stage filter cake formation. This crucial step helps prevent the premature clogging of filter cloths by avoiding the immediate buildup of a dense solids layer.
As the filter press fills, the VFD controller works in sync with the pump to automatically and progressively increase feed pressure. The pressure ramp-up is customizable, depending on the slurry composition and solids concentration, ensuring optimal filtration results.
Typically, the filtration cycle starts at a low pressure of 25 PSI and increases gradually up to a shut-off point near 100 PSI, based on the specific requirements of the filter press. Once the target pressure is reached, the pump automatically shuts off to prevent over-pressurization.
This automated pressure regulation enhances both filtration efficiency and filter cloth lifespan by reducing clogging and maintaining consistent filtration quality. The Apex VFD system integrates smoothly with both new and existing filter press setups, offering flexibility and high-performance filtration for a wide range of industrial applications in the UAE.
Reliable Pumping in Challenging UAE Conditions
In tough environments like those across the UAE, pumps often struggle with cavitation caused by uneven pressure distribution from vanes rotating through fluids. This typically occurs at the point of lowest static pressure, commonly at the vane outlet. The Apex Disk Pump from UAE Pump and Dredge is built to overcome these issues with disk impellers that inherently require a low Net Positive Suction Head (NPSHR).
To further reduce cavitation risk, the Apex impeller is fitted with a built-in axial flow inducer that enhances its low NPSH capabilities, making it highly effective in demanding applications such as desalination plants, wastewater treatment, and industrial slurry management.
The pump is designed to produce a consistent, tangential pressure field across the entire system. This ensures that only positive pressure gradients exist, minimizing the risk of pressure-induced damage and maintaining high operating efficiency. This feature is especially valuable in harsh UAE environments where steady performance and durability are critical.
Optimized Performance for Highly Viscous Liquids
Pumping highly viscous fluids presents major challenges for traditional vaned impellers—lowering pump efficiency, reducing flow capacity, and increasing the required NPSH. Fluids with viscosities around 500 SSU can drastically impair performance in conventional pumping systems.
In contrast, the Apex Disk Pump from UAE Pump and Dredge is engineered to handle viscous fluids with exceptional reliability. The pump’s design features precise disk spacing that accommodates a wide viscosity range, from low-viscosity water-like liquids to ultra-thick substances up to 400,000 SSU.
The flow characteristics of the pump naturally adapt to the viscosity of the fluid. For thinner liquids, the flow remains marginally turbulent, while thicker fluids transition to laminar flow, ensuring stable and efficient performance regardless of fluid density.
This ability to handle a broad viscosity spectrum without compromising efficiency makes the Apex Disk Pump a trusted solution across diverse industries in the UAE, including food processing, oil and gas, wastewater, and heavy manufacturing.

Superior Durability Against Abrasive Liquids
Abrasive liquids with suspended particles can quickly erode internal pump components. The Apex rotating disk pump from UAE Pump and Dredge combats this by utilizing a flow path between two parallel disks, forming a stable boundary layer near the disk walls. This reduces sharp directional changes and rapid accelerations, preserving the protective layer and significantly enhancing resistance to abrasion. The result is long-lasting performance and high reliability when handling abrasive slurries in tough UAE operating conditions.
