Starch powder conveying is a linchpin of food processing, pharmaceuticals, and industrial production—demanding equipment that marries precision, efficiency, and reliability. Modern powder diaphragm pumps already outperform traditional methods by enabling dust-free closed-loop transfer, reducing energy waste, and protecting material integrity. But for one starch processor, their existing pumps fell short of these promises—until BSK stepped in.
The Cost of Outdated Equipment
For years, the customer relied on another brand’s powder pumps, but persistent issues chipped away at productivity. Excessive air consumption inflated energy bills, as the pumps wasted compressed air through poorly designed valves. Their bulky build made repositioning impossible, clashing with the facility’s need for flexible workflows.
Most damaging were frequent blockages. Starch’s fine particles clumped in narrow flow paths, halting production for hours of manual cleaning. Compounding this, the old pumps’ overcomplicated air motors—with dozens of small parts—turned routine maintenance into a labor-intensive hassle. These problems weren’t just nuisances: they led to raw material waste, missed deadlines, and soaring operational costs.
BSK: Amplifying Powder Pumps’ Core Strengths
Powder diaphragm pumps suit starch handling with core strengths: spark-free air-driven operation safe for dust-prone areas, closed-loop transfer to prevent contamination, and gentle fluidization to preserve starch quality. BSK boosts these with targeted innovations:
Anti-Clogging Performance
BSK’s one-key reset clears starch clogs: minor ones in seconds, no disassembly. Optimized airflow keeps powder semi-fluid, handling starch up to 1200kg/m³—far above standard pumps’ 800kg/m³ limit.
Efficiency & Simplicity
BSK’s streamlined air motor slashes air use 30% vs. older models, reducing energy costs. Its modular design uses just 3 Y-shaped ring sets as wear parts, cutting maintenance over 60%. Lightweight but durable, they mount on mobile carts for easy repositioning to match production needs.
The Outcome: A Complete Fleet Upgrade
After testing BSK, the customer saw immediate results: blockages dropped from weekly to monthly, air costs fell by 25%, and maintenance tasks that took hours now take minutes. Impressed by how BSK turns industry advantages into tangible gains, they replaced all old pumps with BSK models. Today, their starch conveying runs continuously—with less waste, lower costs, and fewer disruptions.

Frequently Asked Questions
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.
Can BSK pumps handle food-grade and sanitary applications?
Yes. BSK sanitary AODD pumps feature a 316L body with electropolished finish (Ra ≤ 0.8 μm), tri-clamp connections for CIP, FDA-compliant diaphragms, and no dead legs for complete drainage. They are used in dairy, beverages, sauces, edible oils and chocolate transfer.
Are BSK pumps suitable for explosive / ATEX environments?
Yes. AODD pumps are powered by compressed air with no electricity, making them inherently safe for ATEX Zone 1/2 (gas) and Zone 21/22 (dust). For ATEX compliance use a conductive grounded metallic body or PTFE diaphragms with conductive additive for plastic bodies, and route the air exhaust to a safe area.
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).
