In environmental protection, chemical processing, and mining, sheet frame filter presses are critical for solid-liquid separation—such as sludge dewatering and corrosive chemical slurry filtration. For smooth operation, their supporting pneumatic diaphragm pump must be durable, high-pressure resistant (to push thick slurries), leak-free (to avoid waste and safety risks), and reliable enough to prevent unexpected system shutdowns.
Most filter presses operate outdoors, so pumps also need to withstand rain, humidity, and corrosive slurries. One industrial filtration system manufacturer struggled to find a pump meeting these demands—until switching to BSK pneumatic diaphragm pumps.
Customer Requirements: No Compromise on Reliability
The manufacturer builds industrial filtration equipment, including sheet frame filter presses. Their non-negotiable pump needs were:
- No system shutdowns (presses run continuously; failures cause costly downtime).
- High-pressure resistance (to push thick, particle-rich slurries without performance loss).
- Zero leaks and a robust air valve (leaks waste materials and risk safety; poor valves disrupt flow).
- Outdoor corrosion resistance (to handle rain, dampness, and acidic/alkaline slurries).
Previously, the manufacturer used a well-known brand’s pumps. After long-term testing of BSK pumps—evaluating durability, pressure resistance, and corrosion performance—they found BSK met and even exceeded their standards. This led them to switch to BSK.
BSK’s Advantages: Built for Filter Press Needs
BSK pumps address key filter press challenges starting with corrosion resistance and strength. Unlike standard pumps that rust outdoors, BSK pumps have special anti-corrosion/oxidation treatment: a weatherproof pump body and corrosion-resistant wetted parts (e.g., diaphragms, flow channels), eliminating frequent replacements.
To avoid shutdowns, BSK’s air valve delivers steady pressure for consistent slurry flow under high pressure, with minimal jams or failures. Leaks are prevented by precision diaphragm seals.
Application Results: Stable, Downtime-Free Operation
Since switching to BSK, the manufacturer’s presses have run smoothly—no unexpected shutdowns from pump issues, nearly zero leaks. The anti-corrosion design holds up outdoors and against corrosive slurries, requiring minimal maintenance. This reduced costs and boosted confidence in their filtration systems.

Frequently Asked Questions
Why choose an AODD pump instead of a centrifugal pump?
AODD pumps excel with high-viscosity fluids (up to 10,000 cP), abrasive slurries and shear-sensitive liquids. They run dry without damage, are self-priming, handle solids up to 6mm, and are safe for explosive environments with no electricity. Centrifugal pumps suit very high flow (>1000 L/min) or high pressure (>10 bar).
What industries use AODD pumps?
AODD pumps are used in chemical processing, food & beverage (dairy, wine, CIP), painting & coating, ceramics & mining (slurries, glazes), pharmaceuticals, oil & gas, water treatment, electronics, automotive, and pulp & paper. Their ability to handle abrasives, solvents and shear-sensitive fluids makes them ideal across these sectors.
What pump body materials are available?
BSK offers five body materials: Aluminum alloy (general purpose, oils), Stainless steel 316 (corrosive chemicals, food, pharma), Cast iron (low-cost industrial, wastewater), Polypropylene/PP (acids, alkalis, lightweight), and PVDF (strong acids, solvents, high-purity).
When should I choose PTFE vs Santoprene diaphragms?
Choose PTFE for strong acids, aggressive solvents, high-purity or temperatures above 80°C (shorter flex life, higher cost). Choose Santoprene for mildly corrosive/neutral fluids, longer diaphragm life (2-3x vs PTFE), food-grade use and cost efficiency.
